Stool-eating is more common than owners admit and has several possible explanations. Here's what's behind it and how to address it.
Coprophagia — eating stool, their own or other animals' — is one of those behaviors owners don't love talking about but is surprisingly common. Survey data suggests up to 16% of dogs do it regularly. The causes range from behavioral to medical, and addressing it depends on identifying which applies.
Marketing claims age fast. Mechanism doesn't. Here's a working overview of coprophagia and how to approach it, including when it warrants a vet conversation.
Types of coprophagia
Autocoprophagia — eating one's own stool.
Allocoprophagia — eating another dog's stool.
Cross-species — eating cat stool, horse manure, deer scat, etc.
Each has somewhat different causes and management considerations.
Possible behavioral causes
Mother dogs teach puppies stool-cleaning behavior in the den. Some puppies never outgrow it.
Boredom and lack of stimulation, particularly in dogs left alone for long periods.
Attention-seeking — dogs notice that this behavior gets a reaction.
Anxiety — some compulsive coprophagia has anxiety components.
Learned behavior — dogs in multi-dog households sometimes pick up the behavior from others.
Possible medical causes
Nutritional deficiency — historically blamed but actually rarely the cause in well-fed dogs.
Malabsorption disorders — EPI (exocrine pancreatic insufficiency) can lead dogs to eat their own stool because nutrients are still in it.
Parasites — heavy worm burdens sometimes drive stool-eating behavior.
Cushing's disease, diabetes, certain medications affecting appetite.
These warrant vet workup, especially in adult dogs with new-onset coprophagia.
When to consult your vet
New-onset coprophagia in an adult dog — particularly worth ruling out medical causes.
Coprophagia accompanied by weight loss or other symptoms.
Stool-eating despite adequate calories and quality food.
Persistent behavior that hasn't responded to behavioral interventions.
Always check with your vet before assuming behavioral cause alone.
Behavioral interventions
Immediate cleanup — remove stool from yard and walks. If it's not there, it can't be eaten.
Supervised potty time — be present when your dog goes, redirect their attention immediately after.
'Leave it' training — solid recall and 'leave it' commands help in real-time.
Increased exercise and mental stimulation — bored dogs find creative entertainment.
Avoid punishment-based responses — they often worsen the behavior.
Dietary considerations (with vet input)
For dogs whose coprophagia might have a malabsorption component, your vet may recommend stool testing, dietary changes, or supplementation.
Some products marketed as coprophagia deterrents (For-Bid, Coprophagia tablets) work for some dogs — discuss with your vet before trying.
Adequate nutrition matters — feed appropriate calories and quality. Underfeeding can drive the behavior in some dogs.
Don't make significant dietary changes without your vet's input.
Digestive support angle
Some integrative vets suggest that dogs whose digestion is incomplete may be more drawn to eating stool because it still contains undigested nutrients.
Digestive enzyme supplementation and probiotic support are sometimes used as part of a multi-component approach — under vet guidance.
These aren't standalone solutions but can be part of a comprehensive plan.
Cross-species coprophagia (cat litter especially)
Cat stool is high in protein content and very attractive to many dogs.
Management is primarily environmental — make the litter box inaccessible to the dog.
Cleaning the litter promptly. Baby gates, top-entry litter boxes, or designated cat-only rooms.
Risk of GI upset from clumping litter ingestion. Worth preventing.
Outdoor coprophagia
Wildlife stool — deer, rabbit, raccoon — can transmit parasites, viruses, or contaminants.
Worth talking to your vet about parasite prevention protocols for dogs who routinely eat wildlife stool.
Other dogs' stool poses lower risk if the household practices good parasite prevention.
Common questions about coprophagia
Will my dog get sick from eating stool? Sometimes — depends on what was in the stool and the dog's individual susceptibility. Talk to your vet about specific risks.
Does adding pineapple/meat tenderizer help? Mixed evidence. Some dogs respond, many don't.
Is coprophagia a sign of nutritional deficiency? Rarely in well-fed dogs. But worth ruling out with your vet.
Will my dog grow out of it? Some do, particularly puppies. Many don't without intervention.
What to track at home
Frequency of stool-eating attempts and successes.
Sources (own stool, other dogs', wildlife, cat box).
Any concurrent symptoms — weight changes, appetite changes, GI symptoms.
Response to interventions tried.
Bring these notes to your vet visits.
Where our formulas fit
For dogs whose coprophagia may have a mild digestion or absorption component — and as part of a comprehensive plan guided by your vet — a daily GI support blend may complement the broader strategy. When potential digestive insufficiency in coprophagic dogs is part of the picture, G.I. Balance is the formula we built for general daily gut support. It pairs pumpkin fiber with apple pectin, ginger, and fennel — herbs traditionally used to ease GI tension — plus agave inulin as a prebiotic.

The bottom line
We won't promise a transformation. We'll promise transparency about what we put in the bag and why. The rest is the dog's biology doing what it's built to do — given the right substrates.
