Why Does My Puppy Eat Poop?

Understand stool eating, stop the immediate turn-and-grab routine, and know when health or infection risk needs your vet.

Short answer

Eating faeces is called coprophagia or coprophagy. Puppies may investigate or eat their own stool, another dog's stool, cat poop or wildlife droppings even when they are otherwise healthy. Opportunity and repetition are often important, but hunger, digestive problems or other medical issues can sometimes contribute. Do not assume a vitamin deficiency, and do not wait for a puppy to grow out of it while stool remains freely available.

  • Prevent access: accompany toilet trips and scan the yard or walking route.
  • Let your puppy finish toileting, then call them away and reward them.
  • Pick the stool up immediately while your puppy is with you, not racing you back to it.
  • Practise Leave It away from real faeces; do not use stool as a training test.
  • Do not chase, shout, punish accidents or force the mouth open.
  • Ask your vet about persistent stool eating, especially with unusual hunger, poor growth, weight loss, vomiting, diarrhoea or stool changes.

Unknown faeces can carry infection

Other dogs' and animals' faeces can expose a puppy to parasites or infectious organisms. Risk depends on the source, freshness, local disease and your puppy's health and vaccination status. Contact your vet if the source is known to be infected, your puppy is not fully vaccinated and ate unknown dog stool, or any illness follows.

Is it normal for puppies to eat poop?

It can occur in healthy puppies and dogs, but that does not mean every puppy does it or that persistent coprophagia should be ignored. Exploration and scavenging can explain some episodes. A puppy who repeatedly seeks out stool still needs prevention, and health or feeding questions may need assessment.

A 2018 UC Davis-led questionnaire study found frequent dog-stool eating in 16% of the dogs sampled, defining frequent as at least six observed episodes. That was an owner survey across dogs, not a puppy prevalence study, so it should not be turned into a claim about how many puppies do it. The study also found no relationship with age or diet (study).

Why mother dogs eat puppy poop

A mother dog normally consumes very young puppies' waste while cleaning the nest. Merck Veterinary Manual includes this as maternal behaviour. It helps explain why faeces eating exists in dogs, but it does not prove that an individual puppy learned it from their mother or has a nutritional need.

Why puppies eat poop

There is rarely one answer visible from the behaviour alone. Start with the most direct explanation—stool is accessible and eating it has been practised—then look at the context and health of the puppy rather than working through a speculative list.

  • Exploration or scavenging: puppies investigate many smells and tastes, including faeces.
  • Opportunity and habit: stool left in a yard, kennel or litter tray keeps the behaviour available and rewarding.
  • What happens next: shouting, chasing or wrestling over stool may add attention or make a puppy swallow faster.
  • Hunger or high appetite: an underfed puppy may seek food, but apparent ravenousness can also need a medical review.
  • Digestive or medical factors: parasites, poor absorption or another condition can alter appetite or stool.
  • Stress, confinement or insufficient activity: these can be associated in some dogs, but poop eating alone does not diagnose anxiety or boredom.

Which poop-eating pattern is this?

The pattern tells you what to manage first. It is not a diagnosis.

Does poop eating mean a nutritional deficiency?

Not usually. A deficiency or underfeeding is possible in a poorly balanced or inadequate diet, and disease can interfere with digestion or absorption, but most stool eating should not be treated as proof that a puppy lacks a particular vitamin or mineral. In the UC Davis-led survey, diet was not associated with dog-stool eating.

Feed a complete puppy diet in an amount appropriate for growth, using the food's guide and your vet's body-condition advice. Do not add vitamins, minerals, digestive enzymes or extra meals on guesswork. More expensive food is not an evidence-based coprophagia cure. The feeding and potty schedule covers meal frequency without prescribing portions.

What if your puppy is always hungry?

Check first that the measured daily amount still suits a growing puppy; needs change quickly. Do not simply keep increasing food. Ravenous appetite alongside poor growth, weight loss, frequent or abnormal stools, vomiting or low energy needs a veterinary check.

Parasites, digestion and medical causes

Most cases may be behavioural, but VCA's veterinary behaviour guidance recommends evaluating diet, stool frequency and consistency and checking for parasites. Conditions that reduce nutrient absorption or increase appetite can contribute. The point is not to diagnose a long list of adult diseases in a puppy; it is to notice when the stool eating sits inside a wider health pattern.

Parasites are two separate questions. They can sometimes contribute to poor growth, digestive signs or unusual appetite, and consuming contaminated faeces can also expose a puppy to parasites. One does not prove the other. Cornell notes that puppies are particularly susceptible to illness from coccidia and that contaminated faeces or environments can transmit it.

If your puppy eats their own poop immediately

1

Go out together

Use a lead if your puppy spins back to the stool before they can respond.

2

Let them finish

Do not interrupt normal elimination or loom over them while they are going.

3

Call away

As soon as they finish, use their name or recall and move a few steps from the stool.

4

Reward with you

Give several small treats for coming away and staying with you.

5

Pick up calmly

Keep the puppy with you or take them inside, then collect the stool immediately.

The goal is a predictable sequence—poop, move to the person, get rewarded—not a race between puppy and owner. VCA and the Oregon Veterinary Medical Association both recommend calling the dog over for a reward after elimination and cleaning up promptly.

Other dogs' and wildlife poop

Faeces from unknown dogs or wildlife should be treated differently from a puppy briefly eating their own fresh stool. Other animals may shed parasites, bacteria or viruses without looking ill. Not every exposure causes disease, and risk varies by organism and source, but prevention matters—especially for a young puppy.

On walks, use a lead in contaminated areas, scan ahead and create distance. Practise Leave It with safe setup items, then reward passing stool without approaching it. If abundant faeces makes success unlikely, change route or use a stronger management layer rather than repeatedly testing the cue. The outdoor scavenging guide owns the broader walk plan.

Cat poop and the litter box

Cat stool can be attractive to dogs, and repeated litter-box access is primarily a setup problem. Put the tray somewhere the cat can reach comfortably but the puppy cannot, using the room layout or a suitable barrier. Keep the tray clean and supervise while changing the arrangement so the cat is not frightened away from it. If the puppy also chases, blocks or repeatedly pesters the cat, use the puppy-and-cat troubleshooting guide.

The puppy may swallow litter as well as stool. Call your vet if a large amount was eaten or if vomiting, abdominal pain, reduced appetite, straining or failure to pass stool follows. Do not rely on Leave It while leaving the litter tray freely accessible.

Yards and multi-dog homes

  • Clear existing stool before the puppy goes out. A weekly cleanup is not enough for a puppy actively seeking it.
  • Accompany every toilet trip for now. Free yard access keeps rehearsing the behaviour.
  • Use separate potty trips temporarily if the puppy races toward the other dog's stool.
  • Record which dog's stool is targeted. If it is consistently one dog, mention that to your vet; the other dog's digestion or health may also merit review.
  • Do not blame or punish either dog. Change timing and access instead.

Do not punish potty accidents

Never shout, rub a puppy's nose in stool or punish them after an accident. Punishment can teach a puppy that eliminating near people is unsafe and may add urgency, hiding or attention to the stool-eating sequence. It does not teach where to toilet. Clean calmly, tighten the schedule and reward outdoor elimination. The puppy potty schedule covers the reset.

Leave It, recall and Drop It

  • Recall or name response: most useful immediately after your puppy finishes toileting. Reward moving toward you.
  • Leave It: useful before the puppy reaches stool. Build it with controlled, harmless items first; real faeces is not a beginner exercise.
  • Drop It: may help once stool is already in the mouth, but prevention is more reliable than a mouth battle. Practise with toys, not faeces.
  • Physical removal: do not routinely prise the jaws open, chase or corner the puppy. That can provoke guarding or faster swallowing.

Can a basket muzzle help?

For persistent outdoor ingestion that cannot yet be managed with distance and a lead, a properly fitted basket muzzle may provide a safety layer. Cornell recommends a basket style that permits panting, drinking and treats, introduced gradually and positively. It should not be used unattended or as punishment.

Ask a vet or qualified reward-based professional to help choose and fit a muzzle for scavenging prevention; not every basket design blocks small material. Recheck fit often as a puppy grows. A tight fabric grooming muzzle is not appropriate for a walk.

Do pineapple, pumpkin or stool-eating supplements work?

Evidence is weak and inconsistent. In the UC Davis-led owner survey, none of 11 commercial food additives or tablets meaningfully changed dog-stool eating; reported success was 0–2%. Because it was a questionnaire rather than a controlled treatment trial, it cannot prove that no product ever helps, but it gives little reason to rely on one.

Pineapple, pumpkin, papaya, yogurt and meat tenderizer are repeatedly suggested online, but there is no good evidence that they reliably stop coprophagia. Do not add supplements or digestive enzymes without veterinary advice, and do not put hot sauce, pepper or bitter substances on stool: that still leaves the target available and relies on aversion instead of prevention. Access management and cause assessment matter more.

What to do after your puppy eats poop

  • Stay calm and stop further access. Do not punish after the event.
  • Identify the source if you can: own stool, known household animal, unknown dog, wildlife or cat litter; note when and roughly how much.
  • Ask your vet about a high-risk or unknown source, known infection, medication in the animal whose stool was eaten, or incomplete vaccination with unknown dog-faeces exposure.
  • Watch for illness: vomiting, diarrhoea, blood, abdominal pain, poor appetite, lethargy, dehydration or difficulty passing stool needs veterinary advice.
  • Use ordinary hygiene: wash hands after cleanup and avoid face licking immediately after stool ingestion (CDC).

Faecal contamination—not just swallowing a visible stool—can spread some infections. Canine parvovirus, for example, spreads through contact with contaminated stool or environments (AVMA). Follow your veterinarian's advice about local disease risk and safe places while vaccinations are being completed.

When to call your vet

Arrange a veterinary assessment when stool eating is frequent or persistent, begins suddenly, or occurs with:

  • Weight loss, poor growth or a body-condition change.
  • Constant or sharply increased hunger despite appropriate feeding.
  • Repeated vomiting, diarrhoea, mucus, blood, straining or other stool changes.
  • Abdominal pain, lethargy, dehydration or reduced appetite.
  • A known parasite or infectious-disease exposure.
  • Repeated illness after eating faeces.

Your vet may review the diet and growth curve and recommend a faecal test or other checks based on the whole picture. Do not deworm, supplement or change diets repeatedly without that guidance.

Will your puppy grow out of eating poop?

Some puppies stop as they mature; others continue. There is no reliable age or deadline, and the 2018 survey did not find dog-stool eating related to age. Preventing access now protects health and stops repeated practice whether or not maturity would eventually reduce interest.

If it happens in a crate or pen

A puppy repeatedly toileting and then eating stool while confined may be left longer than they can stay clean, have an unsuitable routine or space, be distressed, or have loose or unusually frequent stools. Do not solve it by making the crate too small or by punishing the puppy. Shorten the interval, arrange a toilet break and investigate health signs. Puppy pees or poops in the crate owns the confinement and elimination plan.

Common mistakes

  • Chasing the puppy around stool or turning cleanup into a race.
  • Punishing accidents or rubbing the puppy's nose in faeces.
  • Assuming a vitamin deficiency and adding random supplements.
  • Relying on pineapple, pumpkin, meat tenderizer or commercial chews.
  • Leaving stool available while expecting a cue to solve the problem.
  • Repeatedly testing Leave It against real stool before the skill is ready.
  • Forcing the mouth open or cornering a puppy who already has stool.
  • Assuming every puppy grows out of it on a predictable timeline.
  • Ignoring ravenous appetite, poor growth, weight loss, vomiting or diarrhoea.
  • Leaving the litter tray accessible or overlooking swallowed litter.
  • Relying on off-leash recall in areas with abundant unknown faeces.
  • Calling it anxiety or boredom from this behaviour alone.
