Puppies often eat their poop (coprophagia) for a mix of instinct, curiosity, and sometimes health or training reasons.

Quick Scoop: The short version

  • It’s very common in young pups and usually normal at first.
  • Often linked to copying mom, boredom, stress, or leftover nutrients in the stool.
  • You should still mention it to your vet, especially if it’s sudden or obsessive.

Why do puppies eat their poop?

1. Instinct and copying mom

  • Mother dogs often eat their puppies’ poop to keep the “den” clean and reduce smells that attract parasites or predators.
  • Puppies may simply mimic this behavior, especially in the early weeks.
  • In many pups, this instinct fades as they mature and learn where to toilet.

2. Curiosity and play

  • Young puppies explore the world with their mouths, so poop can just be “another interesting object.”
  • If they’re bored and have little mental stimulation, the yard or crate becomes a “toy box,” and stool can turn into a gross little “snack.”

3. Attention and training mistakes

  • If every time your puppy eats poop you yell, chase, or react dramatically, they might learn that this is a reliable way to get your attention.
  • Harsh toilet training (like rubbing their nose in accidents) can backfire: some pups start eating the evidence to avoid punishment.
  • Over time, this can turn into a habit that sticks even when the original trigger is gone.

4. Stress, anxiety, or confinement

  • Puppies left alone for long periods, crated too long, or in stressful environments may develop odd coping behaviors, including stool eating.
  • Shelter or kennel backgrounds, frequent scolding, or chaotic households can all contribute.
  • For some pups, it becomes a repetitive, self-soothing behavior when they feel overwhelmed.

5. Diet, digestion, and medical issues

Sometimes the issue is inside, not just in their head:

  • Poor digestion (enzyme problems, malabsorption) can leave undigested food in the stool, making it smell and taste like dog food.
  • Low-quality food or an unbalanced diet might make your puppy seek extra nutrients from poop, especially if they’re very hungry or underfed.
  • Certain medical issues—like exocrine pancreatic insufficiency or intestinal disease—can push dogs to look for nutrients wherever they can, including feces.

Red flags that need a vet check:

  • Weight loss despite good appetite.
  • Chronic or repeated diarrhea or vomiting.
  • Dull coat, low energy, or sudden behavior changes.

Is it dangerous?

  • Eating their own poop is usually less risky than eating other animals’ poop, but it still carries parasite and bacteria risks.
  • Eating other dogs’ or other species’ feces can expose pups to worms, Giardia, coccidia, and other infections.
  • It also makes normal puppy kisses a lot less appealing, and the smell can linger on their breath.

What you can do about it

1. Clean-up + management

  • Pick up poop immediately in the yard or run so your puppy never has a chance to “snack.”
  • Keep your pup on a leash or long line outside so you can gently guide them away after they go.
  • Give a cue like “come” or “let’s go” and reward with a treat before they turn around to investigate their stool.

2. Training and redirection

  • Teach a strong “leave it” and practice with safe items, then apply it to poop if they approach it.
  • Reward them for walking away from the spot, not for staring at the mess.
  • Avoid shouting or chasing—calmly redirect and pay them for making the right choice.

3. Reduce boredom and stress

  • Increase mental exercise: short training sessions, puzzle toys, snuffle mats, and varied safe chew toys.
  • Give predictable routines for feeding, walks, and rest to reduce anxiety.
  • If they’re crated, ensure the crate time is age-appropriate and they aren’t forced to sit with soiled bedding.

4. Check diet and health

  • Ask your vet if the current food is appropriate for your puppy’s age, breed, and activity level; adjust if needed.
  • Your vet may run fecal tests, blood work, or other checks if they suspect a digestive or metabolic issue.
  • In some cases, vets or trainers may suggest stool-taste deterrent supplements, but these work best alongside cleaning and training—not alone.

What’s “normal” vs. when to worry

More “normal” (still gross, but common)

  • Very young puppies occasionally nibbling at their own or littermates’ poop, especially just after weaning.
  • A behavior that gradually fades as you manage the environment and teach good habits.

More concerning

  • Sudden onset in an older puppy or dog.
  • Obsessive or frantic poop eating every chance they get.
  • Paired with weight loss, big appetite, diarrhea, vomiting, or change in mood.

In these cases, a vet visit is important to rule out medical causes and get tailored behavior advice.

Mini example story

Imagine a 4‑month‑old pup who’s crated while their owner works. The puppy poops in the crate, gets bored, investigates, and discovers that stool still smells a lot like their food. Over time, they start doing this every day, and when the owner comes home and freaks out, the puppy only learns that poop and big reactions go together. With quicker clean‑up, a schedule that avoids crate accidents, more toys and training, and calm “leave it” practice, many puppies grow out of the habit and stop seeking poop altogether.

Quick TL;DR

Puppies eat their poop because of instinct, curiosity, boredom, stress, attention-seeking, or diet and digestion issues, and it’s common but fixable with management, training, and sometimes vet help.
