Why Do Dogs Eat Poop? Causes and How to Stop It

Vet verified. Written by Elle Padgham, Communications Lead. Reviewed by Dr. Linda Simon MVB MRCVS, Team Vet.

Dogs eating feces is called coprophagia. It can be exploratory or learned behavior, especially in puppies, but it can also appear with hunger, poor access control, stress, medication effects or medical disease. The safest response is prompt cleanup, supervised bathroom trips, reward-based training and a veterinary check when the behavior is new, intense or paired with other symptoms.

Do not punish, chase or force the dog's mouth open. These responses can create fear, guarding or faster swallowing. Prevent access first, then teach the dog to move away for a better reward.

Why does my dog eat poop?

Merck Veterinary Manual notes that coprophagia may be normal in some contexts. Mother dogs clean waste from very young puppies, and dogs may investigate feces as part of scavenging and exploratory behavior. Repetition can turn one opportunistic event into a practiced habit.

Possible contributors include easy access in the yard or litter box, hunger, a highly food-motivated temperament, boredom, insufficient stimulation, stress, attention after the event or learning to remove evidence after punishment for house-training accidents. More than one factor can operate at the same time.

Does the gut microbiome explain poop eating?

The intestinal microbiome is involved in digestion and health, but a commercial stool test does not prove why an individual dog eats feces. Results vary with diet, medication, age, sample handling and laboratory method. Coprophagia should not be assumed to mean the dog is missing a specific bacterium or needs an unproven supplement.

Why does my puppy eat poop?

Puppies explore with their mouths and can discover feces before an owner cleans it. If people react dramatically, the event may become exciting or the puppy may learn to swallow faster. House-training accidents also create indoor access.

Take the puppy out on a leash, reward immediately after elimination, call the puppy away and clean up before free play. Give age-appropriate meals, sleep, chewing and enrichment. For more stool context, see our puppy poop guide.

Could a health disorder cause coprophagia?

Occasionally, yes. A medical problem that increases appetite, changes digestion or reduces nutrient absorption may contribute. Parasites, intestinal disease, pancreatic disease, diabetes, Cushing's disease and some medications are examples a veterinarian may consider from the full history. Coprophagia alone does not diagnose any of them.

Bring a fresh stool sample if the clinic requests one and list every food, treat, supplement and medication. Report weight loss, ravenous appetite, increased thirst or urination, vomiting, diarrhea, bulky or greasy stool, weakness and abdominal discomfort.

When should I call the veterinarian?

Book an exam when poop eating begins suddenly in an adult dog, becomes frequent, causes conflict, or occurs with weight change, digestive signs, excessive thirst, altered appetite or low energy. Puppies should follow their planned parasite-testing and deworming schedule.

Call promptly after access to feces that may contain medication, toxins, recreational drugs, rodent poison, chemicals or foreign material. Repeated vomiting, severe diarrhea, collapse, tremors, breathing trouble, a swollen painful abdomen or marked weakness needs urgent care.

Is eating poop bad for dogs?

It can expose a dog to parasites, bacteria, viruses, medication residues, toxins and foreign material. Risk depends on the source. Another animal's feces, cat litter, wildlife waste, compost and human waste may add hazards beyond the dog's own stool.

A dog can also carry material on the muzzle and then lick people or household surfaces. Wash hands after waste handling, keep children away from pet waste and maintain routine veterinary care. The CDC recommends washing after contact with dogs, their waste or supplies.

How do I clean my dog's mouth after eating poop?

Move the dog away calmly and offer fresh water. Wipe the outside of the muzzle with a damp cloth if needed. Do not pour mouthwash, peroxide, bleach, essential oil or another disinfectant into the mouth, and do not force a toothbrush into an upset dog's mouth.

Once the dog is calm, follow its normal dog-safe oral-care routine if the mouth is comfortable. Contact the veterinarian for a swallowed toxin, broken tooth, bleeding, choking, repeated vomiting or concern about a high-risk exposure. A dental product cannot sterilize the mouth or make an unsafe exposure harmless.

How to stop a dog from eating poop

Use immediate cleanup and supervised access

Management works faster than waiting for a perfect cue. Take the dog out on a leash, carry bags, and remove feces immediately. Block litter boxes with a layout the cat can use but the dog cannot. Secure compost and outdoor bins. Check yards before free play when multiple dogs share the space.

Teach a reward-based leave-it pattern

Start indoors with a low-value object covered by your hand. Mark and reward the moment the dog looks away. Build toward uncovered objects, then outdoor practice at a safe distance. Use a high-value reward and move away together rather than testing the dog beside feces.

Do not use shock, leash jerks, yelling or physical confrontation. AVSAB recommends reward-based training methods. Punishment can add anxiety and does not change the environment that keeps offering the behavior.

Review meals and enrichment

Confirm that the main diet is complete and balanced for the dog's life stage and that the measured amount matches body condition, activity and veterinary guidance. Do not simply increase food without checking calories. Use part of the meal in safe food puzzles or training to add foraging and problem-solving.

Schedule sniff walks, play, rest and appropriate chewing. A dog with little stimulation and constant yard access may practice scavenging. Enrichment helps, but it does not rule out disease or replace cleanup.

Coordinate every caregiver

Write a simple routine: leash out, wait for elimination, reward away, pick up, then release for play. Keep bags at every exit. Ask family, dog walkers and sitters to use the same cue and never chase. In a multi-dog home, supervise and separate bathroom turns if one dog targets another's stool.

Do not rely on taste deterrents alone

Products added to food or stool have inconsistent results and may not affect every source the dog finds. They can also add ingredients or calories. Ask the veterinarian before using one, especially with disease, medication, a puppy or a diagnostic diet.

What not to do

• Do not punish the dog after the event.
• Do not chase or create a keep-away game.
• Do not pry open the mouth unless an emergency professional directs it.
• Do not use a muzzle unsupervised or as a substitute for cleanup.
• Do not add supplements to treat an assumed deficiency without diagnosis.
• Do not let the dog lick faces after waste exposure.

Frequently asked questions

Do dogs eat poop because they are missing nutrients?

Not necessarily. Behavior and access are common explanations. A veterinarian should investigate medical or nutritional concerns from the full history instead of assuming a deficiency.

Will pineapple or a supplement stop poop eating?

There is no reliable universal food remedy. Prompt cleanup, supervision, reward-based training and medical assessment when indicated are more useful.

Can my dog get worms from eating poop?

Yes, exposure to infected feces can transmit some parasites. Follow the veterinarian's testing and prevention plan.
