Why Does My Dog Eat Poop?
It’s gross to us but common and usually normal in dogs. Coprophagia can be instinct, curiosity, boredom, or learned habit - and only sometimes points to a diet or health issue.
It’s more normal than you think
Eating poop, known as coprophagia, is surprisingly common, especially in puppies and some adult dogs. Mother dogs clean up after their litters by eating their puppies’ waste, and pups explore the world with their mouths, so a phase of poop-eating is a normal part of canine development. For most dogs it is an unpleasant habit rather than a sign that something is wrong.
Common reasons
Dogs may eat poop out of boredom or to get attention (even a horrified reaction is attention), out of hunger or because they find it tasty (cat poop and other animals’ droppings are a particular temptation), or out of stress and anxiety. Occasionally it can reflect a diet that leaves them feeling under-nourished, or a medical issue affecting absorption. Dogs left alone in a yard for long periods sometimes start the habit simply because there is little else to do.
When to check with your vet
While usually harmless, a sudden new interest in eating poop can occasionally signal a digestive or nutritional problem worth ruling out. It is also worth a vet check if your dog is losing weight, seems extra hungry, or the behaviour appears alongside other changes. Eating other animals’ faeces can also expose your dog to parasites, so keep up with worming.
How to stop it
The most effective approach is management: pick up after your dog promptly, keep the cat’s litter tray out of reach, and make walks and play more enriching so boredom is not a factor. Teach a solid “leave it” cue and reward your dog for coming away from droppings. Avoid punishment, which can make anxious dogs worse; calm redirection and a clean environment work far better.

It is normal, which is not the same as harmless
Eating faeces has a clinical name, coprophagia, and an unhelpful reputation. It is common enough in dogs to be considered within the range of ordinary canine behaviour, and it is very common indeed in puppies. Knowing that will not make it pleasant, but it should stop you concluding that something is deeply wrong with your dog, because usually there is not.
It is also not harmless, and the reason is not the behaviour itself but what travels with it - parasites and infectious organisms move between animals this way, which is the practical argument for addressing it rather than shrugging. The health question and the disgust question have the same answer, which is convenient.
Why puppies do it, and why most stop
Puppies investigate the world orally and indiscriminately, and a puppy who eats faeces is usually doing exploration rather than anything more meaningful. Bitches clean up after their litters, which normalises the behaviour in the nest, and puppies copy what they see. Most grow out of it without intervention as their exploration becomes more selective.
The two things that stop most puppies growing out of it are attention and opportunity. A puppy who is shouted at, chased across the garden or physically wrestled away from it has learned that this particular object produces an immediate and dramatic reaction from you, which for many puppies is a reward rather than a deterrent. And a puppy with unlimited unsupervised access to a garden that is not picked up simply gets more practice. The first thirty days with a new puppy covers the supervision habits that prevent most of this.
The adult dog who starts, or never stopped
An adult dog doing this consistently is worth a conversation, particularly if it is new. Some of the explanations are behavioural - boredom, anxiety, learned attention-seeking, or a dog who was punished for toileting indoors and is now disposing of the evidence, which is a genuinely well-documented consequence of house-training gone wrong.
Some are not behavioural. Conditions that affect how well a dog absorbs nutrients, or that dramatically increase appetite, can drive it, and so can being genuinely underfed. That distinction is not one you can make from home and it is not one to guess at. If your dog is eating well but losing weight, or is ravenous in a way he did not used to be, that combination alongside this behaviour is a reason to book an appointment rather than to buy a deterrent.
What actually works
Management first, because it is the only part that works immediately. Pick up promptly and consistently, in the garden and on walks. A dog cannot eat what is not there, and every occasion he does not get to practise is progress. This is unglamorous and it is most of the solution.
Then supervision. Go out with him rather than sending him out, so you are present at the moment it matters. Teach and pay generously for a reliable recall and a “leave” cue, practised somewhere boring long before you need it somewhere interesting. When he does approach, call him away and reward warmly - you are competing for his attention, and you need to be worth more than the alternative.
Then enrichment, because a dog with enough to do is a dog with less reason to invent occupations. Sniffing walks, puzzle feeding, training sessions, and enough exercise for his breed and age.
What to avoid
Do not punish it after the fact, or at all. Punishment reliably makes this behaviour worse, both by adding value through attention and by teaching some dogs to do it faster and out of sight. Do not chase him for it, which turns it into a game with a prize.
Be sceptical of additives sold to make faeces unpalatable. The evidence for them is thin, they do nothing about other animals’ faeces, and adding anything to your dog’s food is a conversation to have with your vet rather than a purchase to make on a hunch. The same caution applies to anything from your own cupboards - the first aid page explains why that rule holds without exception.
When it stops being a habit question
Phone your vet if this is new in an adult dog, if it comes with weight loss, a changed appetite, diarrhoea or vomiting, or if your dog is eating faeces from other species and you do not know what those animals have been exposed to. Routine parasite control is a discussion for your vet, who will set what is appropriate for your dog and where you live - it is not something to arrange from a search result.
Go in with detail: when it started, how often, whose faeces, indoors or out, supervised or not, and what his weight, appetite and stools have been doing. The two-minute preparation covers making the appointment count, and if he has eaten something and you are worried about what was in it, start instead at what to do when your dog has eaten something. Keeping the garden and the house clear of what he should not reach is the same groundwork as pet-proofing your home.
Most quirks are perfectly normal. If a behaviour changes suddenly or comes with other signs of illness, check with your vet. Full disclaimer.
