Pet owners experience the most disturbing and confusing behavior when they discover their dog consuming fecal matter. Your dog starts eating feces without warning which forces you to find an immediate solution for this new problem. The behavior known as coprophagia occurs frequently in dogs. The solution process needs less emotional response because it demands more investigative work.
This vet-recommended guide will explain the multiple factors that drive your dog to eat poop and present a detailed plan to help you control this behavior permanently.
What Are the Instinctual Reasons My Dog Eats Poop?
The behavior of eating feces might not be a problem because it stems from natural instincts. Mother dogs naturally consume their puppies' waste to protect their den from predators while maintaining cleanliness. Young puppies develop this behavior through two possible mechanisms: they learn from their mother or they use their mouths to explore their environment.
Research conducted in 2018 established that dogs might have inherited the behavior of eating feces as a survival mechanism from their ancestors. Scientists believe dogs consume fresh feces because it allows them to eliminate parasites before they reach maturity which protects their pack from infections. The behavior persists because dogs retain their ancestral instinct to consume feces.
Could Medical Issues Cause My Dog to Eat Poop?
The first thing you need to determine is whether your dog has any medical issues. A dog who starts eating feces for the first time as an adult needs to visit a veterinarian right away. The behavior indicates possible health issues that need medical evaluation.
Nutrient Malabsorption and Maldigestion
When dogs experience poor nutrient absorption they will attempt to retrieve these nutrients from their stool. The presence of dog poop undigested food becomes visible to owners. The inability of Exocrine Pancreatic Insufficiency (EPI) and Inflammatory Bowel Disease (IBD) to function properly as digestive enzymes results in malnutrition which drives dogs to consume their own stool.
Increased Appetite (Polyphagia)
Diseases that affect the body can create an endless feeling of hunger in dogs. The combination of Diabetes and Cushing's disease and steroid medications leads dogs to develop such intense hunger that they start eating everything including feces.
Dietary Deficiencies & Parasites
Modern commercial dog food provides homemade dog food supplements guide to most dogs but occasional nutrient deficiencies might trigger this behavior. The main reason for this behavior stems from internal parasites that live inside dogs.
What Behavioral Triggers Lead to Poop Eating?
When your veterinarian declares your dog healthy then behavioral factors become the primary reason for this behavior.
-
Stress, Anxiety, or Boredom: Dogs who spend extended periods alone without proper exercise or mental stimulation will consume feces because they need something to do.
-
Attention-Seeking: Your dog will learn to eat feces because they receive instant attention from you when they approach poop even though the attention is negative.
-
Learned Behavior (Fear): The practice of harsh house-training methods leads dogs to develop a habit of eating their own feces as a way to hide their accidents.
A Vet-Recommended Action Plan to Stop the Habit
The solution to stop coprophagia needs multiple steps which do not include any quick fixes.
Step 1: Consult Your Veterinarian
Your first essential action should be to consult with your veterinarian. Your veterinarian will perform tests which include fecal parasite detection and blood tests to identify any medical conditions from the list above.
Step 2: Manage the Environment (The #1 Strategy)
The instinctual nature of your dog makes environmental management the most successful treatment approach. The main objective requires complete blocking of access to all areas.
-
Immediate Cleanup: The "Clean Slate" strategy requires you to immediately retrieve stool when your dog defecates outside.
-
Leash Up: The leash serves as a control measure to prevent your dog from reaching for stool during walks even in your home yard.
-
Litter Box Lockdown: The litter box needs to be placed in a location which your dog cannot reach (behind a baby gate or on a high surface) when they show interest in cat feces.
Step 3: Use Training and Enrichment
While you handle environmental control you should teach your dog to perform alternative actions.
-
Teach "Leave It": The "Leave It" command stands as the most essential command for dogs who eat their own feces. Start training with unimportant treats while providing strong rewards for successful completion.
-
Create a New Routine: Your dog should receive a high-value treat immediately after completing their defecation while you call them to you with joy. The process teaches your dog that coming to you brings better rewards than checking their feces.
What About a Supplement to Make My Dog Stop Eating Poop?
Many pet owners seek fast solutions through powders and chews and supplement to make dog stop eating poop which claim to stop dogs from eating their own feces. The 2018 study revealed that taste-aversion products failed to deliver any significant results because their success rate approached zero (1).

Frequently Asked Questions
Why do dogs eat their own poop?
Coprophagia — the act of eating feces — can be driven by a range of factors including nutritional deficiencies, enzyme or probiotic imbalances, boredom, anxiety, learned behavior, or a desire to clean their environment (common in mother dogs). In puppies, it is often exploratory behavior that resolves with age.
Is eating poop dangerous for dogs?
Eating their own feces carries lower risk than consuming another animal's stools. However, feces can contain intestinal parasites, harmful bacteria, and residual medications or toxins from other animals. Preventing the behavior and ensuring regular parasite control is important for your dog's health.
Can a digestive issue cause my dog to eat poop?
Yes — some dogs eat feces because they sense undigested nutrients in it, which can be a sign of malabsorption or digestive enzyme deficiency. Supporting gut health with a digestive enzyme supplement and ensuring adequate nutrition can sometimes reduce this behavior. Plentum's All-in-One Dog Powder includes digestive enzymes and postbiotics to help maintain optimal digestion.
How can I stop my dog from eating poop?
Effective strategies include promptly cleaning up the yard, supervising your dog on walks, using positive reinforcement to redirect attention, and adding deterrents (such as pineapple or commercial additives) to the diet. Addressing any underlying digestive or nutritional imbalances is equally important.
When should I see a vet about my dog eating poop?
If the behavior starts suddenly in an adult dog, is accompanied by weight loss, loose stools, or other health changes, or persists despite management efforts, a vet visit is warranted. Sudden onset coprophagia can sometimes indicate a medical issue such as malabsorption, parasites, or pancreatic insufficiency.
