Dog Eating Poop? How to Stop Coprophagia in 7 Days
Coprophagia is one of the most common and most fixable canine behaviors. Identify which of the four causes you are dealing with, run the seven-day protocol, and the behavior stops in most dogs within two weeks.
Coprophagia, the technical term for eating feces, affects an estimated 16 percent of dogs frequently and 24 percent at least once, according to a 2018 University of California Davis behavioral study. It is gross, but it is also normal for many dogs. The four causes ranked by frequency are: normal instinctive behavior (especially in puppies and mother dogs), dietary or digestive enzyme gaps, boredom and stress, and learned attention-seeking. The fix is a combined dietary, environmental, and behavioral protocol. Yard cleanup is non-negotiable. Most cases resolve in seven to fourteen days.
Why Dogs Eat Poop
Coprophagia traces back to evolutionary biology. Wolves and other wild canids occasionally eat feces to keep dens clean, recover undigested nutrients, and reduce parasite exposure for pups. According to the American Kennel Club, the behavior in modern dogs likely descends from this clean-den instinct. Mother dogs consume puppy stool reflexively, and puppies often imitate the behavior. Most puppies outgrow it by 9 to 12 months. Adult dogs that continue or start coprophagia are doing it for one of three other reasons: a digestive issue, boredom and stress, or because past attempts to stop the behavior accidentally reinforced it.
The ASPCA divides coprophagia into two functional categories: autocoprophagia (eating their own stool) and allocoprophagia (eating another animal's stool). Autocoprophagia is more often dietary. Allocoprophagia, especially cat litter and wildlife scat, is more often opportunistic and behavioral. The intervention differs.
Four reasons dogs eat poop:
- Normal instinct, especially in puppies and intact females
- Dietary or digestive enzyme gaps
- Boredom, stress, or under-enrichment
- Learned attention-seeking from owner reactions
The 2018 UC Davis study, the largest behavioral analysis of coprophagia to date, found that coprophagic dogs were no more likely to have malabsorptive disease than non-coprophagic dogs, suggesting the behavior is more often behavioral than medical. That said, sudden-onset coprophagia in an adult dog that never did it before is medical until proven otherwise.
Normal Instinct (Most Common)
This is the dominant cause in puppies, young adult dogs, and intact females, particularly mother dogs. The behavior is not pathological. It is the same instinct that drives mother dogs to consume puppy waste to keep the whelping area clean. Puppies imitate the mother, and the habit can persist into early adulthood before fading on its own.
Most puppies who eat poop will stop on their own by 12 months without intervention. The behavior is most embarrassing during the early socialization months and during housetraining. Aggressive punishment during this window often backfires and creates a furtive eater who hides the behavior or eats more quickly when caught.
Signs normal instinct is the driver:
- Dog is a puppy under 12 months, or an intact female with recent litter
- Eats stool immediately after defecation, often their own
- Otherwise healthy: normal energy, weight, coat, appetite
- No vomiting, diarrhea, or weight loss
- Behavior is casual, not frantic
Dietary or Digestive Enzyme Gaps
Dogs with poor nutrient absorption sometimes engage in coprophagia. The theory is that undigested nutrients in the stool smell and taste like food, and the dog re-consumes it. Conditions that drive this include exocrine pancreatic insufficiency (EPI), small intestinal bacterial overgrowth (SIBO), inflammatory bowel disease (IBD), and severe parasitism. Low-quality diets with high carbohydrate fillers and low digestibility also drive the behavior in some dogs.
According to VCA Animal Hospitals, nutritional deficiency is a documented but uncommon cause of coprophagia. The behavior is more often behavioral than medical, but the medical workup is essential for sudden-onset adult coprophagia.
Signs dietary or digestive issues are the driver:
- Sudden onset in an adult dog
- Soft, voluminous, or greasy stool
- Weight loss despite normal or increased appetite
- Dull coat, flaky skin
- Excessive flatulence or borborygmi (gurgling gut sounds)
- Eats own stool specifically, not other dogs'
Boredom, Stress, or Under-Enrichment
Bored dogs eat poop. Stressed dogs eat poop. Dogs kept in long crate stretches, kennels, or solo backyard time without enrichment use coprophagia as a self-stimulating activity. The behavior is functionally similar to chewing furniture, digging, or excessive licking: an outlet for an unmet need.
This is the dominant cause in adult dogs that did not have coprophagia as puppies but developed it later, often after a lifestyle change: working from home stopped, dog moved to a kennel, household added a new pet, or a routine shifted.
Signs boredom or stress is the driver:
- Dog is left alone or under-stimulated for long periods
- Recent change in routine or environment
- Other boredom behaviors: excessive licking, destructive chewing, pacing
- Eats poop most when unsupervised, less when active
- Dog is not a puppy and not on a poor diet
Learned Attention-Seeking
Some dogs learn that eating poop gets a big reaction. Owner yells, runs over, makes a fuss, sprays water, chases. To the dog, this is interaction, and even negative interaction is reinforcing if the dog is under-stimulated socially. The behavior persists because it works.
This is the cause behind dogs that look at the owner, make eye contact, and then deliberately approach the stool. The dog is not eating because they want the stool. They are eating because they want the show.
Signs learned attention-seeking is the driver:
- Dog makes eye contact before approaching the stool
- Behavior happens more when owner is watching
- Stops or slows when owner is genuinely not paying attention
- Big reaction history: yelling, chasing, spraying
- Often paired with other attention-seeking behaviors
7-Day Plan to Stop Coprophagia
Yard and Environmental Cleanup
Pick up every piece of stool in the yard. Walk the dog on leash and pick up immediately. No exceptions for the next seven days. If you have a cat, move the litter box to a location the dog cannot reach.
Diet Audit
Confirm the food is a complete and balanced AAFCO diet with high digestibility. If the diet is questionable, plan a 7 to 10 day transition to a better food. Add a digestive enzyme supplement designed for dogs.
Add a Deterrent
Commercial coprophagia deterrents containing yucca, glutamic acid, and parsley work in roughly 25 to 30 percent of cases. Pineapple, pumpkin, or meat tenderizer with bromelain in the food works in a similar percentage. They are not magic, but they help.
Train Leave It
Use high-value treats (chicken, cheese, freeze-dried liver). Practice in the house first, then yard, then in the presence of stool. Reward heavily for the redirect.
Add Exercise and Enrichment
30 to 45 minute walk twice a day. Puzzle feeder for dinner. Two short training sessions. The goal is to drain mental and physical energy so the dog has less drive to invent activities.
Vet Visit If Needed
Trigger criteria: sudden onset in an adult dog, weight loss, soft or greasy stool, vomiting, increased thirst, or other GI signs. Ask for a fecal exam, bloodwork, and B12 if GI disease is suspected.
Decide
Improving? Continue the protocol for three more weeks to lock it in. No improvement? Likely a medical or attention-driven case requiring deeper intervention.
What Not to Do
- Do not punish the dog after the fact. Punishment teaches the dog to hide the behavior, not stop it, and damages trust.
- Do not rub the dog's nose in stool. This is folk advice that has no behavioral validity and harms the dog.
- Do not yell or chase. You are reinforcing the behavior with attention.
- Do not leave stool in the yard. Even one missed pile resets the training timeline.
- Do not give human laxatives or remedies. Some are toxic and most do not address the cause.
- Do not switch foods abruptly. A 7 to 10 day transition prevents the diarrhea that would compound the problem.
- Do not assume it is just a phase in an adult dog with new-onset coprophagia. Sudden onset warrants a vet visit.
Frequently Asked Questions
Four main reasons in order of frequency: normal instinctive behavior (especially in puppies and mother dogs), dietary or digestive enzyme gaps, boredom and stress, and learned attention-seeking from owner reactions. A 2018 University of California Davis study found that 16 percent of dogs eat poop frequently and 24 percent have done it at least once.
Pick up stool immediately, no exceptions. Add a digestive enzyme supplement or switch to a higher-quality food. Train a reliable leave it cue. Increase exercise and enrichment. For yard dogs, add a meat tenderizer with bromelain or a commercial coprophagia deterrent to food. Most cases resolve in seven to fourteen days when all four are done together.
Eating their own fresh stool is low risk. Eating other dogs' stool can transmit parasites including roundworms, hookworms, whipworms, giardia, and coccidia. Cat litter consumption can cause toxoplasmosis or intestinal blockage. Wildlife scat can transmit parvovirus and other diseases. Keep your dog on monthly parasite prevention.
Sometimes. Dogs with pancreatic enzyme insufficiency, malabsorption, or low B-vitamin status sometimes engage in coprophagia. Switching to a higher-digestibility food and adding a digestive enzyme supplement resolves a significant subset of cases in two to four weeks. Bloodwork can rule out malabsorptive disease.
Coprophagia is normal puppy behavior. Mother dogs eat puppy stool to keep the den clean, and puppies imitate the behavior. Most puppies outgrow it by 9 to 12 months. Manage with immediate cleanup, supervision, and a strong leave it cue. Do not punish the behavior.
The folk remedy of feeding pineapple, meat tenderizer, or pumpkin works in some dogs by making the stool taste worse. Effectiveness is roughly 20 to 30 percent. Commercial coprophagia deterrents containing yucca, glutamic acid, and parsley have similar success rates. Behavioral and environmental fixes work better.
Yes. Teach a reliable leave it cue using high-value treats. Practice in low-distraction settings first, then increase difficulty. Pair training with environmental management: pick up stool immediately, keep the dog leashed in the yard initially, and reward going to you after pooping. Most dogs learn in two to four weeks.
Sudden onset coprophagia in an adult dog warrants a vet visit. Possible causes include digestive disease, pancreatic enzyme insufficiency, parasites, Cushing's disease, diabetes, or a medication change. Run bloodwork, a fecal exam, and review any recent diet or medication changes.
Cat litter can cause intestinal irritation and rarely obstruction, and cat stool can transmit toxoplasmosis and intestinal parasites. Long term it is also a major contributor to bad breath. Block access to the litter box with a baby gate, a covered box with a cat-only entry, or by relocating it to a room the dog cannot enter.
The Bigger Picture
Coprophagia is one of the most common reasons owners post on dog forums and one of the easiest behaviors to fix once you identify the cause. Puppies almost always outgrow it. Adults usually have an enrichment, dietary, or attention reinforcement issue. The treatment plan is consistent: immediate yard cleanup, dietary upgrade, enrichment, and training. Do all four together and most cases resolve in a week or two.
If your dog also eats grass, the underlying behavior may be linked. Our guide on why dogs eat grass covers the foraging and dietary side of unusual eating behaviors, and the same enrichment fixes often help both. Coprophagia is also frequently paired with anal-gland issues; if you're seeing your dog scoot across the floor, that's a separate signal worth addressing on its own. For dogs that show broader signs of digestive or skin issues, why dogs itch so much covers food sensitivities and the gut-skin axis. Puppies especially benefit from a clean foundation, and our guide on new puppy checklist mistakes walks through the early routines that prevent coprophagia from becoming a fixed habit. If your dog seems unusually lethargic alongside the new eating behavior, dog sleeping more than usual helps separate normal slowing from concerning illness.
