What Is Coprophagia (Poop Eating) in Dogs?

If you’ve ever watched your dog eat poop and thought, “Why do dogs eat poop?!” — you’re not alone. The habit even has a scientific name: coprophagia. It simply means the behavior of eating feces. While it’s gross to us, many veterinary behavior experts note that it’s relatively common in dogs and can have both behavioral and medical causes. American Kennel Club+1

Understanding why dogs eat poop can help you know when it’s just an odd dog thing… and when it might be time to call your vet.

Is It Normal for Dogs to Eat Poop?

Surprisingly, yes — in some situations.

• Mother dogs often lick and clean their puppies and may eat their stools to keep the nesting area clean and odor-free. Vca+1

• Puppies commonly explore the world with their mouths and may try eating poop out of curiosity. Many grow out of it as they mature. Vca+1

A large survey study led by Dr. Benjamin Hart at UC Davis found that a significant number of dogs engage in coprophagia at least occasionally, suggesting it’s a fairly common canine behavior rather than something rare or “strange.” PMC

Still, that doesn’t mean you have to accept it — especially if it’s frequent or sudden.

Why Do Dogs Eat Poop? Common Behavioral Reasons

1. Instinct & Den-Cleaning Behavior

Some experts believe coprophagia may come from an instinct to keep the living area clean and reduce parasites or smells that could attract predators in the wild. San Francisco SPCA+1

2. Learned Behavior from Other Dogs

Dogs can learn by watching other dogs. If a puppy sees its mother or another dog eating stool, it may copy the behavior and turn it into a habit. Kindness Animal Hospital+1

3. Boredom or Lack of Enrichment

Dogs that don’t get enough mental stimulation or physical exercise may start eating poop simply as “something to do.” Boredom and under-stimulation are commonly listed behavioral reasons for coprophagia. Vca+1

4. Attention-Seeking

If your dog notices that you react strongly every time they go near poop, they may repeat the behavior to get a reaction — even if it’s negative attention. Vca+1

5. Stress or Anxiety

Changes in routine, moving homes, new pets, or long periods alone can increase anxiety in some dogs. Several veterinary and behavior sources note that stressed or anxious dogs may develop habits like poop eating as a coping mechanism. Kindness Animal Hospital+2CareCredit+2

6. Trying to “Hide” Accidents

Dogs that have been punished harshly for indoor accidents may learn to eat their stool to hide the evidence. This is one reason positive, reward-based training is so important. Kindness Animal Hospital+1

Medical Reasons Dogs Might Eat Poop

Sometimes, why dogs eat poop has less to do with behavior and more to do with what’s happening inside their bodies. That’s why it’s important to talk to your veterinarian, especially if the behavior is new or becoming more frequent.

Veterinary sources list several possible medical contributors: Partners Animal Hospital West Loop+3Vca+3Vca+3

1. Nutritional Deficiencies or Poor Diet

If a dog isn’t absorbing enough nutrients from their food — or if their diet is unbalanced — they may try to “recycle” nutrients by eating stool.

• Poor-quality food

• Inadequate calories

• Lack of certain vitamins or minerals

can all contribute to this.

2. Malabsorption & Digestive Disorders

Conditions that interfere with digestion and absorption, such as exocrine pancreatic insufficiency (EPI), can lead to stool that still contains undigested nutrients. Dogs may be attracted to this and try to re-ingest it. Vca+2Partners Animal Hospital West Loop+2

3. Parasites

Intestinal parasites can “steal” nutrients from your dog, potentially leaving them feeling hungrier and more likely to eat stool. Parasites can also be picked up from poop, creating a cycle that only a vet can properly diagnose and treat. Kindness Animal Hospital+1

4. Increased Appetite from Medical Conditions

Some diseases — such as diabetes, Cushing’s disease, or thyroid issues — and certain medications (like steroids) can cause increased appetite or unusual eating behaviors, including stool eating. Vca+1

Important: Only a veterinarian can determine whether a medical condition is contributing to your dog’s coprophagia. Never self-diagnose based on online information alone.

Is It Dangerous When Dogs Eat Poop?

From an owner’s perspective, the behavior is unpleasant — but it can also be a health concern:

• Dogs can ingest parasites, bacteria, or viruses when eating stool, especially if it’s from other animals. ASPCA Pet Insurance+1

• Eating cat poop, wildlife feces, or other dogs’ waste can expose your pet to additional pathogens or dietary triggers. American Kennel Club+1

Again, your veterinarian is the best person to evaluate risk and recommend testing or treatment if needed.

How to Help a Dog That Eats Poop (With Your Vet’s Guidance)

While every dog is different, veterinary and behavior experts often recommend a combination of medical evaluation, management, and training. American Kennel Club+2Vca+2

1. Talk to Your Veterinarian First

Before trying supplements or training alone, schedule a vet visit to:

• Rule out nutritional deficiencies

• Check for parasites

• Screen for digestive issues and other health conditions

This is especially important if coprophagia is new, frequent, or paired with weight loss, lethargy, vomiting, or diarrhea.

2. Improve Yard Cleanliness (Pick Up Promptly)

The more poop that’s available, the more opportunity your dog has to eat it. Regular, prompt dog waste removal is one of the simplest ways to reduce access.

If you’re busy or overwhelmed, a professional pooper scooper service like Doggie Doodies can help keep your yard consistently clean so your dog has fewer chances to snack on stool.

3. Address Boredom & Enrichment

Since boredom is a common reason dogs eat poop, try:

• Longer or more frequent walks

• Puzzle feeders and interactive toys

• Training sessions and games

• Rotating toys to keep things interesting

Mental and physical exercise can redirect your dog’s energy into healthier behaviors.

4. Use Positive Training & Management

• Reward your dog for coming to you after they poop, instead of hovering behind them.

• Teach a strong “leave it” cue and reward heavily when they obey.

• If needed, use a leash outside for a while so you can interrupt stool-eating attempts and redirect.

Avoid punishment — it can increase anxiety and may even make the behavior worse over time. Kindness Animal Hospital+1

5. Discuss Supplements or Deterrents with Your Vet

Some veterinary products are designed to make stool less appealing if your dog eats their own poop. These should only be used under veterinary guidance, since they don’t address underlying health issues and may not work for every dog. Vca+1
