New Puppy: The First 30 Days, Day by Day

There is a moment, usually somewhere in the second evening, when the house has gone quiet and you are sitting on the kitchen floor at an hour you would not normally be awake, looking at a small animal who is looking back at you, and the thought arrives fully formed: I have no idea what I am doing.

Everybody has that moment. It is not a sign that you chose badly, and it is not a sign that something is wrong with your puppy. It is what happens when a life that had a settled shape acquires a small, sharp-toothed creature who does not know the shape yet and will not learn it by being told. The gap between the two is the first month, and the first month is mostly a matter of nerve.

This page is a companion for those thirty days. It is deliberately not a list of commands to teach or a scoresheet to fall behind on. It is the underlying structure - what your puppy is actually doing at each stage, why the obvious response is often the wrong one, and what the calm version of each week looks like. Read it once before your puppy arrives if you can. Then come back to whichever week you are in and read only that.

Two promises about what follows. First, nothing here is health advice: where a passage touches the edge of your puppy’s health, it routes you to your vet rather than pretending to answer. Second, nothing here is a deadline. Puppies are not on a schedule, they are on their own schedule, and the single most useful skill of the first month is noticing which one you are working to.

Brought home a kitten instead - or as well? Cats need a different first month to dogs: a single room rather than a whole house, a litter tray rather than a schedule, and a play sequence rather than a training plan. The feline companion to this page is New Kitten: The First 30 Days.

Before the puppy arrives, it is worth walking the house once with fresh eyes. Pet-Proof Your Home: The Room-by-Room Audit is the long version of the proofing work described below, room by room, with a printable checklist and a hazard map you can walk with.

One more thing to have on the shelf before you need it: puppies grow into dogs who go places, and the first car journey, first ferry or first flight goes far better when the carrier has been part of the furniture for weeks rather than arriving on the morning. Travelling With Your Pet: The Preparation System has the acclimatisation ladder, the countdown, and the honest conversation about whether a journey is right for a particular animal at all.

The month, drawn on one line

Before any of the detail, here is the arc. It is worth having in your head, because almost every bad decision in the first month comes from trying to be at a later point on this line than your puppy is.

THE FIRST 30 DAYS, AS ONE LINE

  DAY 0      DAYS 1-3      WEEK 1        WEEK 2        WEEK 3        WEEK 4
    |-----------|-------------|-------------|-------------|-------------|
  arrive     decompress    rhythm        widen        foundations    wobble
  quiet      no visitors   routine set   the world    lead + name    testing
  small      no outings    crate begun   alone-time   recall games   settle
  world      sleep         vet seen      begun        deeper         deeper

  The line only moves forward when your puppy has become BORED
  of where they currently are. Boredom is the signal to widen.
  Excitement is not. Fear is a signal to go back a step.

  Nobody has ever lost anything by going back a step.

That last line is the whole method. Everything else on this page is a worked example of it.

The one rule that makes the first month work

Here it is: lower the bar until your puppy can clear it, then raise it so slowly that they never notice. That is the entire technique. It applies to being left alone, to the crate, to meeting strangers, to traffic, to the vacuum cleaner, to being handled, to walking past a bin bag flapping in the wind.

The reason it works is that puppies do not learn what you intended to teach. They learn what actually happened to them. A puppy who is shut in a crate for an hour on the first night does not learn that the crate is a bedroom; they learn that the crate is where the panic happened. A puppy taken to a busy high street at eight weeks does not learn that towns are normal; they learn that towns are overwhelming and that you did not help. In both cases the intention was good and the lesson was the opposite.

The corollary is uncomfortable but freeing: going too slowly costs you almost nothing, and going too fast can cost you months. If you are ever unsure which way to err in the first thirty days, err downwards. You cannot ruin a puppy by being too boring.

The second half of the rule is about you. You will be tired, and tiredness makes people escalate. The moment you notice yourself getting louder, sharper, or more insistent, that is the moment to put the puppy somewhere safe and go and stand in another room. Nothing you teach in that state will be the thing you wanted to teach.

Before the door opens: proofing the rooms they will actually use

Puppy-proofing is usually described as a whole-house project, which is why most people never finish it. Do the opposite. Pick the two or three rooms your puppy will genuinely be in for the first month - almost always the kitchen, one living space and the route to the garden or door - and make those rooms boringly safe. Everywhere else can simply be shut.

Get down on the floor. Not metaphorically: physically kneel and look along the skirting boards at puppy eye height. You will find things you have walked past for years. The trailing charger cable. The gap behind the washing machine. The bin that opens if you lean on it. The bag of shopping that lives on the floor for ten minutes every week.

The category that matters most is the one people forget, because it is not a hazard for an adult dog: a puppy puts everything in their mouth, and they do it fast. The window between noticing and swallowing is genuinely a second or two. Removal is the only reliable control.

Two numbers to have written down before the door opens, on paper, on the fridge, where anyone in the house can find them without unlocking a phone: your own vet, and whoever covers your vet out of hours. Our printable emergency pack exists for exactly that, and takes about five minutes to fill in on a calm afternoon.

And bookmark two things now, while nothing is happening: what to do when your dog eats something and the poison control directory. Not because you expect to need them, but because the hour you need them is the hour you will not be able to think of a search term.

Day 0: the journey home and the first few hours

Today your puppy loses everything they have ever known: their mother, their littermates, the smell of the only room they have lived in, and the rhythm of the days. Whatever else happens today, that is the thing that is happening. Almost every sensible decision on day 0 follows from taking it seriously.

The journey

Bring someone with you if you can, so one person drives and one person sits with the puppy. Bring a towel and something absorbent, and accept in advance that the car may not go well; car sickness and car fear are very common on this particular journey and mean nothing about your dog’s future. Keep the car quiet. Resist the urge to pass the puppy round like a christening.

Ask the breeder or the shelter for something that smells of the litter - a piece of bedding, an old jumper. It is not sentimental; scent is the sense your puppy trusts most, and one familiar smell in an entirely unfamiliar room does real work on the first night.

The first hour at home

Do less than you want to. Carry your puppy to the garden or the toilet area first, put them down, and stand there quietly until something happens or clearly is not going to. Then bring them into the one room you have decided is theirs, and let them explore it at their own pace while you sit on the floor and mostly ignore them.

Ignoring them is the gift. A puppy who is allowed to approach you, sniff you, wander off and come back is learning that you are a safe fixed point. A puppy who is picked up every time they move is learning that they have no control over anything, on the day when they have already lost control of everything.

No visitors today. Not the neighbours, not your sister, not the friend who has been waiting three weeks. This is the single most commonly ignored piece of advice about day 0 and the one most likely to produce a puppy who finds people overwhelming. The people can come next week and the puppy will be a better host.

Food on day 0

Feed exactly what they have been eating, in the form they have been eating it. Today is not the day to improve their diet. A puppy who refuses their first meal in a new house is extremely common and usually about stress rather than appetite - but a puppy who is not eating or drinking at all, or who seems flat rather than merely subdued, is a call to your vet, not a wait-and-see. Small animals have very little in reserve.

The change to whatever you intend to feed comes later and slowly, and there is a whole post on doing it without upsetting anyone: how to switch your pet’s food safely. Amounts are a conversation for your vet and the food itself; if you want a starting point to take to that conversation, the dog food calculator will give you one.

The first night, honestly

The first night is bad. Not always, but often enough that you should plan for it rather than hope. Your puppy has never slept alone in their life. Every night before this one has been spent in a warm heap of siblings. The crying is not manipulation and it is not a test of your resolve; it is a young animal doing the one thing that has always worked, which is calling for the pile.

You will find two camps online. One says never go to them or you will teach them that crying works. The other says let them sleep on your bed forever. Both are answering a different question from the one you have.

The practical answer that almost every experienced person converges on: sleep near your puppy for the first few nights. On the sofa, on a mattress on the kitchen floor, with the crate or pen beside your bed - whichever suits your house. Close enough that they can hear and smell you, so the panic never fully starts. You are not creating a habit you will be stuck with; you are removing the reason to panic, and a puppy who has never panicked at night is far easier to move away from later than one who has.

Then move outwards over the following nights, a little at a time, in the same lower-the-bar way as everything else. Bed beside you, then across the room, then the doorway, then the next room. If a step produces distress, go back one and stay there longer.

Days 1 to 3: the decompression window

The first three days have one job: let the puppy discover that this place is dull and safe. That is it. Not one thing needs to be taught. Nothing needs to be socialised. There is no outing worth making and no visitor worth having.

The reason is that a frightened or overloaded animal cannot learn anything you want them to learn. The brain that is busy tracking whether the world is safe has no capacity left over for names, houses, rules or people. Rush this window and you spend weeks undoing it. Respect it and week two arrives with a puppy who is already halfway to confident.

What decompression looks like in practice is almost aggressively boring. The same rooms. The same few people. Sleep, a lot of it, undisturbed. Short pottering sessions in the garden. Meals in the same place at roughly the same times. Nothing new brought into the house on purpose.

Two things you should start on day 1, though, because both are cheap now and expensive later:

• Toilet trips on a clock, not on a hunch. See the next section - this is the thing that decides how long house-training takes.
• Being alone for seconds at a time. Not hours. Seconds. Walking out of the room and back in before anyone has noticed. This is the seed of the alone-training section further down, and starting it in a week when nothing else is going on is a genuine gift to yourself.

One more thing worth saying out loud: some puppies are quiet for the first two or three days and then become an entirely different animal on day four, when the world stops being frightening and starts being interesting. That is not a change for the worse. That is the real puppy arriving. If your puppy has been suspiciously easy, week two may surprise you, and it is normal.

If you took on an older rescue rather than a young puppy, the same window applies and matters even more; our post on the first 48 hours with a rescue dog goes further into it.

House-training is a schedule, not a lesson

Almost everyone gets house-training wrong in the same way. They treat it as something the puppy must understand, and then they get frustrated when the puppy does not appear to understand it. It is not that kind of problem. House-training is a plumbing problem with a habit attached, and the only variable you actually control is how often the puppy is standing on the right surface at the moment the need arrives.

Very young puppies have very little storage and almost no warning. There is frequently no circling, no sniffing, no signal at all - the need arrives and is met in the same second. Waiting for a sign is therefore a losing strategy in the first weeks. You go out on a schedule instead, and the schedule is generous to the point of feeling silly.

A PUPPY DAY, DRAWN AS OPPORTUNITIES

  first thing on waking ....... OUT
  after every meal ............ OUT
  after every drink ........... OUT
  after every nap ............. OUT
  after every burst of play ... OUT
  after any excitement ........ OUT
  before settling anywhere .... OUT
  last thing at night ......... OUT
  once in the night ........... OUT  (silent, no play, straight back)
  and in between .............. OUT  (on the clock, not on a hunch)

  --------------------------------------------------------------
  Every OUT is a chance to be right in the place you want.
  An accident is a chance you missed, not a rule they broke.
  --------------------------------------------------------------

The three-part move that does the actual teaching

• Go out with them, every time. Not opening the door and waiting inside. You have to be there, or you do not know what happened and you cannot mark it.
• Stand still and be dull until they go. No playing, no talking, no walking about. You are furniture. If they get distracted, wait. Do not fill the silence.
• Make the moment they finish the best moment of the hour. Quiet, warm praise the instant they stop, and something they genuinely like. Then, if you want to play, play - so that going out is not always the end of the fun.

That is the whole mechanism. You are not teaching a rule. You are stacking up hundreds of occasions on which the right surface was followed by something good, until the right surface becomes the default preference. Habit, not comprehension.

About the hours-per-month rule of thumb

You will find a widely repeated formula that converts a puppy’s age into the number of hours they can wait. Treat it as trivia rather than a timetable. It varies enormously between individuals, it is meaningless when a puppy is excited or has just drunk, and its real effect on most households is to give people permission to wait when they should have gone out. Go out more often than any formula suggests. There is no cost to a needless trip.

When there is an accident

Say nothing. Not a sigh, not a groan, not a “no”. Clean it up when the puppy is not watching, and clean it properly - ordinary household cleaners can leave a smell that reads, to a dog, as a marked spot. An enzymatic cleaner made for the job is the thing that stops a repeat performance in the same corner. If you find yourself getting several accidents in the same place, that is information about your schedule and your cleaning, not about your puppy’s character.

And never, ever put a puppy’s face near it. That is the next section.

Why punishment breaks house-training specifically

This deserves its own section because the failure mode is so specific and so common, and because the damage looks exactly like success for a fortnight.

Here is what happens. A puppy has an accident. Somebody is cross - a shout, a scruff, a face pushed towards the mess. The puppy has no ability to connect your anger with an event that is now over; what they connect it with is the thing in front of them, which is you, and the puddle, in the same moment.

The conclusion the puppy draws is not “I should go outside”. It is “producing this in front of a human is dangerous”. So they stop producing it in front of you. They go behind the sofa. They go upstairs. They wait until you leave the room. And - this is the expensive part - when you take them into the garden and stand there, they will not go, because you are watching, and then they come inside and relieve themselves the moment your back is turned.

At that point you have a puppy who appears to be defying you, and who is in fact doing exactly what you taught them. Undoing it takes weeks of being conspicuously, boringly pleased about the whole business, and some dogs never fully lose the caution.

The same mechanism damages far more than house-training. A puppy told off for growling learns to skip the growl, not to stop being uncomfortable - and a dog with no growl left is a dog with no warning system. A puppy told off for chewing the wrong thing while you are in the room learns to chew it when you are not. Punishment does not remove behaviour. It moves it out of your sight, which is the worst possible place for it to be.

The crate is a bedroom, not a cupboard

A crate or a pen is one of the most useful things in a puppy household and one of the easiest to ruin in a single evening. Used well it is a place your dog chooses to go, which means you have a safe place to put them when the front door is open, when the children’s party is happening, when the plumber is in, or when they simply need to sleep and cannot stop themselves joining in.

Used badly - shut in before it means anything, left to cry, used as a punishment - it becomes a box the dog associates with being trapped, and you will never fully get that back.

The difference is entirely a matter of pace. Here is the pace, as a ladder. You only climb a rung when the rung below has become boring. Not tolerated. Boring.

THE CRATE LADDER
climb only when the step below has become BORING

  step 8 |  shut, you out of sight, longer, sometimes
  step 7 |  shut, you out of the room, briefly
  step 6 |  shut, you in the room, a good chew inside
  step 5 |  shut for a few seconds, opened BEFORE any complaint
  step 4 |  meals eaten inside, door open
  step 3 |  goes in, turns around, comes out, food follows
  step 2 |  food tossed in, puppy free to go in and out
  step 1 |  door fixed open, bed inside, nothing asked of anyone
  =======+=====================================================
         |  If a step produces distress, the step below was
         |  not boring yet. Go back down and stay longer.
         |  Going back down costs nothing. Pushing on costs
         |  you the crate.

Three rules that keep it a bedroom

• Never use it as a telling-off. Not once. The moment it becomes where you go when you are in trouble, it stops being where you go to rest.
• Open the door before they ask. Every time you let them out because they cried, you have taught crying. Every time you let them out during the quiet, you have taught quiet. In the early rungs this means being almost comically quick.
• Do not use it to hold a puppy past their capacity. A crate cannot solve a toilet-schedule problem. A puppy forced to soil their own bed loses the instinct that makes crates work at all, and that is genuinely hard to rebuild.

If a crate is not for you, a pen or a puppy-proofed room with a gate does the same job. The principle is the same either way: your puppy needs a place where nothing is asked of them, and you need somewhere to put them that is not a fight.

Week 1: building the shape of a day

Once decompression has done its work, week one is about rhythm. Puppies are enormously reassured by predictability, and a predictable day does more for a puppy’s confidence than any exercise you could do with them.

You are not building a rigid timetable. You are building a recognisable sequence, so that your puppy can tell what kind of moment they are in: this is a meal moment, this is an out moment, this is a play moment, this is a settle moment. Sequence matters more than clock times.

What is not on that list is instructive. No walks. No dog parks. No visitors in numbers. No formal training sessions. No trying to teach a recall in the garden while three people watch. Week one is foundations, and foundations are dull by design.

If you would like a milestone view of the same period that covers kittens as well, the puppy and kitten first-eight-weeks tracker runs alongside this page, and the shorter first eight weeks post is a quicker read for anyone else in the house who is not going to read all of this.

Sleep: the most underestimated thing about puppies

If you take one behavioural idea away from this page, take this one. A very large share of what people describe as bad puppy behaviour is a tired puppy who cannot stop.

Puppies sleep a great deal - far more of the day than they are awake - and unlike a human baby they do not reliably drop off when they have had enough. What they do instead is speed up. The bitey, frantic, running-in-circles, cannot-settle, grabbing-your-trouser-leg puppy at half past seven in the evening is not being difficult. They are past the point of being able to stop themselves, and the more you interact, the further past it they get.

The intervention is unglamorous and works startlingly well: when the wheels come off, put the puppy somewhere quiet and let them sleep. Crate, pen, quiet room, covered basket. Not as a punishment and with no drama - just a boring transfer to a place where nothing is happening. Most of them are asleep within minutes, and most people are astonished the first time.

The other half of this is protecting sleep when it is happening. A sleeping puppy should not be woken to be admired, photographed, moved, or shown to a visitor. If there are children in the house, the rule that a sleeping dog is invisible is worth establishing on day one and enforcing without exception, for the child’s sake as much as the dog’s.

Teeth: bite inhibition and why “no” is not the tool

Puppies bite. All of them, constantly, and harder than people expect. It is not aggression and it is not a warning sign about your dog’s temperament. Mouths are how puppies investigate the world, and play with the litter was mostly a matter of teeth.

What you are aiming for in the first month is not “stops biting”. It is bite inhibition: a dog who has learned, through hundreds of small experiences, that human skin is astonishingly fragile and that teeth on it end the fun. That learning is worth far more over a lifetime than obedience, because it is the thing that makes an adult dog’s startled reaction a bruise rather than a wound.

The mechanism

In the litter, when a puppy bit too hard, the other puppy squealed and stopped playing. The lesson was not delivered by authority; it was delivered by consequence, immediately, every single time. You are standing in for the littermate.

• Teeth touch skin, the game ends. Not a telling-off. A calm, complete withdrawal of attention: hands away, stand up, turn away, a few seconds of nothing, then carry on.
• Be boring about it. High-pitched yelping works for some puppies and winds others up considerably. If yelping makes yours more excited, drop it and just go quiet and still.
• Redirect before you correct. Have something legal within reach in every room. A puppy with a mouthful of appropriate chew is not a puppy with a mouthful of your wrist.
• Never play games that use hands as the toy. Wrestling and hand-slapping games are the most common cause of a six-month-old dog who grabs hands, and it is the same household who then ask why.
• Check the clock and check the sleep. See above. The worst biting of the day is nearly always the overtired biting.

There is a second wave of this at around the time the adult teeth start arriving, when the chewing becomes more determined and more constant. That is teething rather than misbehaviour. Chewing goes up, and the answer is more appropriate things to chew rather than more restriction. If anything about your puppy’s mouth looks sore, bleeding beyond the ordinary, or is putting them off eating, that is a vet question and not a training question.

Our post on how to stop puppy biting goes into the week-by-week version of this in more detail.

The socialisation window, and why its timing matters more than its list

This is the most important section on the page, and the one most likely to be done wrong with the best intentions.

Young puppies go through a period in which their brain is unusually willing to file new things under “normal”. During it, an unfamiliar object, sound, surface or person can be met, found uninteresting, and stored as part of the furniture of the world. After it, the same brain becomes appropriately cautious about the unfamiliar - which is good survival design and inconvenient for a dog who has to live in a human town.

The window is already open when your puppy comes home, and a substantial part of it belonged to whoever raised them. It narrows during the weeks you have them. That is why the first month matters so disproportionately: you are working inside a period that is closing, and it does not reopen.

THE SOCIALISATION WINDOW

  |###################|~~~~~~~~~~~~~~|--------------------->
  ^                   ^              ^
  wide open           narrowing      effectively closed
  (mostly before      (still very    (learning continues,
   you had them)       useful)        but slowly and at cost)

  |<--- breeder / shelter --->|<--- YOU, starting now --->|

  ---------------------------------------------------------
  What matters is not how many things you tick off.
  It is how many of them your puppy found BORING.
  One calm meeting beats ten overwhelming ones, and one
  frightening meeting can outweigh a fortnight of good ones.
  ---------------------------------------------------------

The part people get wrong

Socialisation is widely understood as exposure, so people produce exposure: the puppy is carried into town, passed between strangers, taken to a busy park, introduced to eleven dogs in an afternoon. The puppy is technically socialised and is in fact being flooded, and the lesson stored is not “the world is fine” but “the world is a lot and nobody helps”.

Socialisation is not exposure. It is exposure at an intensity the puppy can find boring. The measure of a successful outing is a puppy who noticed the thing, looked at it, and then looked away because it was not interesting. A puppy who is frozen, whose weight is back, who will not take food, who is trying to get behind your legs, is not being socialised. They are being frightened, and you should quietly increase the distance.

Doing it properly

• Distance is your volume control. Watch the bin lorry from the end of the street rather than the kerb. If the puppy is tense, go further away, not closer.
• One new thing at a time. A new place with new people and new dogs and a new surface is four new things, and they multiply rather than add.
• Let the puppy choose to approach. Never carry a puppy towards something they are unsure about, and never let a stranger loom over a puppy who has not offered to come.
• Quality over quantity, always. Three calm minutes on a bench watching the world is worth more than an hour of being handled by a queue of admirers.
• Finish before they are tired. Leave while it is still going well. The last minute is the one they remember.

The bit that needs your vet, not this page

When your puppy can safely be on the ground in public places is a veterinary question. It depends on their vaccination status, on what is circulating where you live, and on your vet’s judgement about your individual dog. It differs between countries. It is not something a web page can responsibly tell you, and we are not going to.

Ask your vet directly at the first visit: when can he be on the ground in public, and where is safe before then? Then plan around the answer they give you. In the meantime there is an enormous amount of socialisation available that does not involve public ground at all: your own garden, your own house, the boot of a parked car with the tailgate up, a friend’s garden, being carried, and the doorstep.

Week 2: widening the world without flooding it

By week two the house is understood, the sequence of the day is recognisable, and the puppy has become bored of your kitchen. That boredom is your cue.

Widening means one new element at a time, each returned to often enough that it stops being new. A visitor - one, who ignores the puppy on arrival and lets the puppy come to them. A different room. The front doorstep, sitting quietly, watching the street go past. A short car journey that ends somewhere pleasant rather than at the vet, so the car is not only associated with needles.

The temptation in week two is to declare the difficult part over and start behaving normally: the party, the pub garden, the family visit, all in one weekend. Resist it for one more week. You will get all of that, and you will get it with a dog who copes.

Settling deserves a word, because it is a skill and nobody teaches it. A dog who can lie down and do nothing in the presence of interesting things is a dog you can take anywhere. You build it by putting something long-lasting to chew on a particular mat, in the room where you are, while you deliberately do nothing interesting. Repeat until the mat itself makes them yawn. It is the least exciting training you will ever do and the one you will use most.

Alone-training: build it before you need it

Being left alone is not natural to dogs and it is not natural to puppies at all. It is a learned skill, and like every other skill on this page it is learned in pieces small enough to be boring.

The mistake almost everyone makes is to spend the first two weeks never leaving the puppy for a moment, out of kindness, and then to go back to work. From the puppy’s point of view, the world contained a person constantly and then it did not, with no intermediate stage. That is exactly the recipe for a dog who cannot be left, and it is much harder to fix than to prevent.

So start on day one, at a scale that feels absurd.

THE ALONE LADDER
each rung repeated until it is dull, then the next

  rung 7 |  out of the house, gradually longer, varied
  rung 6 |  out of the front door, back before any fuss
  rung 5 |  upstairs / other floor, doing something noisy
  rung 4 |  another room, door shut, a few minutes
  rung 3 |  another room, door shut, a few seconds
  rung 2 |  out of the room and back, immediately
  rung 1 |  behind a gate, in sight, while you make tea
  =======+===================================================
         |  RETURN BEFORE THE COMPLAINT, NOT AFTER IT.
         |  Coming back to a crying puppy teaches crying.
         |  Coming back to a quiet puppy teaches quiet.
         |  If you are not sure, the rung is too high.

What makes it work

• Leave undramatically and return undramatically. No long goodbyes, no ecstatic reunions. Departures and arrivals should be the dullest events of the day.
• Give them something to do as you go. A chew or a stuffed toy that outlasts your absence turns “the human left” into “the good thing started”.
• Vary the length. Ten short absences and one longer one, in no predictable order, rather than a steadily increasing count they can anticipate.
• Watch what they do in the first minute. If you can, record it. A puppy who settles in the first minute is fine; a puppy who is still pacing or vocalising is telling you the rung was too high.
• Do not use the crate to force it. Alone-training and crate-training are two ladders and you climb them separately before you ever combine them.

If you already see real distress when you leave - destruction focused on doorways, persistent howling, refusal to eat while alone, soiling in an otherwise clean dog - stop improvising and get help. Genuine separation distress is a welfare problem, not a discipline problem, and it responds far better to a qualified behaviourist working with your vet than to anything you will read in a forum. Ask your vet for a referral. It is a completely ordinary thing to ask for.

Week 3: lead, name and the beginnings of recall

By week three there is a household. The puppy knows where things are, sleeps in a predictable pattern, and has opinions. This is the point at which what you do starts to look faintly like training, although it should still look mostly like a game.

The lead

Lead work starts indoors, with no walk attached. Harness or collar on, something good happens, harness off. Then lead clipped on, something good happens, lead off. Then a few steps across the kitchen with the lead trailing, then a few steps with you holding it and going nowhere in particular.

The single most useful habit to establish is that a tight lead means the world stops. When the lead goes tight, you stand still. When it slackens, you move again. You do not pull back, you do not jerk, you simply become a very boring anchor. Done from the beginning, before there is any strength in the dog, it costs nothing. Established late, it takes months.

The name and the check-in

The name is not a command. It is a promise that looking at you is worth it. Say it once, and when the head turns, something good happens. Never say it twice. Never say it to interrupt something they are enjoying unless you are prepared to make the interruption worthwhile.

Alongside the name, reward the check-in: any moment your puppy looks up at you of their own accord, mark it and make it pay. A dog who habitually checks in with you is most of a recall already.

Recall, the version that survives adolescence

Recall is built indoors and in the garden, at short distances, with no distractions, long before it is ever needed. Two people, a few metres apart, calling the puppy back and forth, each of them making an enormous fuss. A puppy chasing you as you run backwards down the hall. Hiding behind a door and calling once.

• Only ever call once. A word repeated into empty air becomes background noise.
• Never call for something the puppy will dislike. If it is bath time, go and get them. Do not spend your recall word on it.
• Make coming back better than what they left. Not a pat. Something genuinely good, at least at this stage. You are buying reliability for later, and it is cheap now.
• Do not test it. Set it up so they succeed every time. Recall is one of the few things where a failure genuinely costs you ground.

Where the lead can go and what surfaces are safe in public is, again, a question for your vet rather than for us. And if the weather is warm, check whether the ground is too hot to walk on before you go anywhere - puppy pads are softer than adult ones and the tarmac test matters more, not less.

On the subject of how much exercise a growing dog should get: less than you think, and it depends on the dog. Growing joints do not benefit from long forced walks, and a puppy will happily run themselves past the point of sense. Our post on how much exercise dogs actually need covers the shape of it; the specific answer for your puppy belongs to your vet, especially with the larger and faster-growing breeds.

Week 4: the wobble

Somewhere around the fourth week, a good many households discover that things have gone backwards. The puppy who was house-trained has had three accidents. The puppy who came when called now looks at you and carries on. The puppy who was fine with the neighbour’s recycling bin now barks at it as though it has personally offended them.

This is so common that its absence is more remarkable than its presence. There are a few things going on at once, and none of them is a failure on your part.

• Confidence. A settled puppy explores more, tests more and pays less automatic attention. The compliance of week one was partly caution.
• Fear periods. Puppies go through phases in which previously boring things suddenly become alarming. It is a normal developmental stage, not a regression you caused. The response is to reduce pressure, increase distance, and let them look at the frightening thing from somewhere they feel safe. Never drag a puppy towards something they are frightened of “to show them it is fine”.
• Your own drift. By week four the toilet trips have quietly become less frequent, the schedule has loosened, and the puppy is being left in rooms alone unsupervised. Most week-four accident clusters are, on honest inspection, a schedule problem.
• Teething. Chewing intensifies and concentration drops.

The remedy is not more discipline. It is a temporary return to week one: tighten the schedule, shorten the alone-time, go back a rung on whichever ladder has wobbled, protect sleep harder, and wait. It passes. It usually passes within days of you going back a step.

Week four is also when the honeymoon ends emotionally for the humans, and it is worth saying plainly: a lot of people quietly wonder, around now, whether they have made a terrible mistake. That feeling is so common it has a name in rescue circles. It is not a verdict on you or on your dog. It almost always lifts. Talk to somebody who has done it before rather than sitting with it alone.

The vet visits: what they are for, not when they are

You will not find a vaccination schedule on this page. That is deliberate, and it is not squeamishness: the correct schedule depends on which diseases circulate where you live, on the products your vet uses, on your puppy’s age and history, and on national practice that differs considerably between countries. Your vet sets the schedule. Anything else you read, including from us, is at best a rough guess about somebody else’s country.

What we can usefully tell you is what the visits are for, so that you get more out of them.

Questions worth taking with you

• When can my puppy be on the ground in public places, and where is safe before then?
• What is your preventive healthcare plan for a puppy in this area?
• What are your out-of-hours arrangements, and what number do I actually ring at 3am?
• What should make me phone you rather than wait for the next appointment?
• What is a sensible feeding approach for this breed and this growth rate?
• When would you like to see us next, and what for?

If it helps to have a structure for tracking appointments, our vaccination schedule generator and the accompanying vaccination schedule explainer are organisers, not prescriptions - they hold the dates your vet gives you so you do not lose them, and the dates still come from your vet.

Money is worth planning for before it becomes urgent, because cost is the thing that most often delays a phone call that should not have been delayed. Our guide to what vet care involves financially is there so that a decision about a puppy is never a decision made in a panic.

What normal looks like, and what should make you pick up the phone

This is the section where we are most careful, because the honest answer to “is this normal?” is that a web page cannot see your puppy and your vet can.

Some things really are ordinary in the first month: a couple of days of reduced appetite around the move, sleeping enormously, hiccups, sneezing at dust, wild bursts of running followed by collapse, nipping, whining at night, chewing everything, and a puppy who is fine one minute and asleep the next.

But the thing that matters is not whether a sign appears on a list. It is change. You are the only person alive who knows what your puppy was like yesterday. A puppy who is different from their own normal - flatter, quieter, less interested, not doing the things they were doing this morning - is worth a phone call, whatever the list says.

The one that catches puppy owners out

Swallowing things. It is the single most common reason a first-month puppy ends up at a vet, and it happens in the two seconds you spent looking at your phone. A sock. A stone. A whole plastic wrapper. The corner of a rubber toy. Something out of the bin. Something off the pavement.

If it happens, do not wait to see what develops and do not try to make your puppy bring it back up - the reasons that goes wrong are worth reading on a calm day rather than a bad one. Phone, and have three facts ready: what it was, roughly how much, and when. Our dog ate something guide and the poison control directory are built for that hour. If there is a cat in the house too, the cat version is separate for good reasons.

Water is the other thing worth being loosely aware of, in both directions. A puppy who suddenly drinks far more than usual, or who stops drinking, is telling you something worth a phone call; the water intake calculator is a way of noticing a change rather than a target to hit.

Things people do in month one that make month two harder

None of these are catastrophes and none of them are moral failings. They are simply the well-intentioned moves that reliably cost people time later.

• Never leaving the puppy alone. Kindness now, real difficulty later. Start the alone ladder on day one.
• Inviting everyone round in the first week. Your friends will still exist in week three.
• Treating exhaustion as naughtiness. The evening monster is a tired puppy.
• Using hands as toys. It is funny at eight weeks and it is not at eight months.
• Repeating a cue that is not working. Each repetition teaches that the word is optional.
• Chasing the puppy who has stolen something. You have just invented the most exciting game in the world, and taught them that stolen goods produce a chase. Swap for something better instead, cheerfully, every time.
• Telling a puppy off for growling. You are removing the warning, not the feeling.
• Free access to the whole house. More space is not a kindness to an animal who cannot yet cope with it, and it multiplies both accidents and swallowed objects.
• Comparing your puppy to somebody else’s. Especially online. The dog in the video is not in week three.
• Skipping handling practice. The cheapest thing you will ever do, and the one you will most regret skipping at the first nail trim - our post on nail trimming without the drama explains why it is nearly all groundwork.
• Waiting to see, when something about your puppy has changed. Phone.

What to do this week

Pick where you are. Each panel is the short version of everything above, for that stage only.

The printable 30-day checklist

Tick as you go, or print the page and put it on the fridge. Nothing here is stored, saved or sent anywhere - the ticks live in your browser tab and vanish when you close it, which is exactly as much as a checklist needs to do. It is not a test, and nobody has ever completed one of these in order.

Day 30 and beyond

At the end of the first month you will not have a finished dog. You will have something better: a puppy who finds your house unremarkable, who has slept enough, who has not learned to be frightened of you, and who has a rough idea that good things happen near humans. Everything else is built on that.

What comes next is adolescence, and it is worth knowing in advance that it will look like everything falling apart. Recall stops working. The settle disappears. Things that were fine become terrifying, and then fine again. It is a phase, it is normal, and the households who come through it best are the ones who go back to basics rather than escalating.

The habits worth carrying past day 30, in order of how much they will save you:

• Keep leaving them alone. Even on the days you are home. Especially on the days you are home.
• Keep socialising for months. Calm exposure, at distances they find boring, does not stop being useful when the window narrows - it just gets slower.
• Keep the crate a bedroom.
• Keep paying for check-ins. Recall is maintained rather than achieved.
• Keep handling them. Every easy vet visit for the next fifteen years is being bought now.
• Keep protecting sleep. It stays true for adolescents.
• Keep phoning your vet about changes. The instinct that something is different is the most useful diagnostic instrument in the house.

And if you want a rough sense of how your puppy’s growth is going, the puppy weight predictor and the pet age calculator are amusements more than instruments - useful for planning a harness size or a car boot, not for judging health. Growth is a conversation for your vet.

Where this page sits

This is a prevention page. It belongs to the calm part of the site, the part you read on a Tuesday afternoon rather than at midnight. The rest of Paw Multiverse is mostly built for the other kind of hour, and it is worth knowing where those pages are before you need them.

Everything on this site is free, has no affiliate links, and is written by people who are not vets and say so. Our disclaimer spells out exactly what that means.
