The first eight weeks with a new puppy or kitten decide the next fifteen years — the habits, the health baseline, the trust. Here is the whole period as one calm plan, week by week, with the free tools on this site doing the remembering for you.
Before they arrive: pet-proof the food situation
Most first-week emergencies are eaten, not caught. Print the Toxic Foods Fridge Chart and stick it where everyone — including kids and visitors — will see it. Chocolate, grapes, xylitol gum and onions cause the classic disasters; when in doubt, the Food Safety Search answers “can they eat that?” in seconds.
Week 1: settle, do not socialize
The first days are about safety and calm, not visitors and dog parks. One quiet room, the same food they were weaned onto (switch later — gradually, over 7–10 days), and short, predictable routines. For rescues, our first-48-hours guide applies doubly.
Weeks 2–4: the vaccine clock is already running
Core vaccinations start at 6–8 weeks and run on a schedule that is easy to fumble. Enter your pet’s birth date into the Vaccination Schedule Generator and you get every window as real calendar dates — including anything already missed. Book the first vet visit in week one even if shots are not due yet: you want a baseline exam and a relationship before you ever need an emergency.
Weeks 4–6: socialization, gently
Between vaccine rounds, expose them to sounds, surfaces, handling and calm strangers — in your arms or your garden, not the dog park. This window shapes adult temperament more than any training class later will. Learn to read what they are telling you with the body language decoder.
Weeks 6–8: routines become rules
Feeding times, toilet spots, alone-time practice in tiny doses, and handling paws and ears weekly (future-you, trimming nails, will be grateful — here is the no-drama method). Keep treats under 10% of daily calories, and check every new “safe” human food against the chart first.
The one number to know before you need it
Save your vet’s number and your nearest emergency clinic in your phone tonight. If something ever goes wrong, our emergency hub is one tap away on every page of this site — the red button in the corner on mobile. You will probably never need it. That is the point of setting it up now.
Quick answers
When should a puppy or kitten get its first vaccines?
Core vaccinations start at 6–8 weeks, with boosters at 10–12 and 14–16 weeks, then a 1-year booster. Enter the birth date into our Vaccination Schedule Generator to get every window as real calendar dates.
What foods are most dangerous for pets?
Chocolate, grapes and raisins, xylitol (sugar-free gum), onions and garlic, alcohol and cooked bones top the list — and lilies are life-threatening for cats even in tiny amounts. Print the Toxic Foods Fridge Chart so everyone in the house knows.
When can my puppy meet other dogs?
Fully socializing at parks is safest about two weeks after the final puppy vaccination (usually around 16–18 weeks). Before then, socialize gently — carried in your arms, in your garden, with known healthy dogs.
How do I know if it is a real emergency?
Collapse, breathing trouble, seizures, a swollen hard belly, inability to urinate, or eating something toxic are always emergencies — go to a vet immediately. For everything else, our 2-minute Triage Helper gives a calm next step. When in doubt, call: vets prefer needless calls to late ones.
