How to Get Your Dog to Stop Eating Poop: A Coprophagia Guide

Why Do Dogs Eat Poop? Understanding Coprophagia

Coprophagia — the technical term for stool-eating — is one of the most common and most frustrating behaviors dog owners deal with. Research published in the Journal of the American Veterinary Medical Association suggests that up to 25% of dogs will engage in coprophagia at some point in their lives, with the behavior most prevalent in puppies under 12 months old.

Before you can stop the behavior, you need to understand what's driving it. Coprophagia typically falls into two categories:

• Behavioral coprophagia: Attention-seeking, boredom, anxiety, learned behavior from a mother dog cleaning up after puppies, or a response to punishment-based house training (the dog eats evidence to avoid being scolded).
• Medical coprophagia: Nutrient malabsorption, exocrine pancreatic insufficiency (EPI), intestinal parasites, Cushing's disease, diabetes, thyroid disorders, or diets deficient in calories or specific nutrients.

According to the Merck Veterinary Manual, the majority of adult-onset coprophagia cases have an underlying medical component that should be ruled out before assuming it's purely behavioral.

Medical Causes: Rule These Out First

If your dog has suddenly started eating feces — especially if they never did before — schedule a veterinary exam. Your vet will likely run the following diagnostics:

When to call the vet immediately: If coprophagia is accompanied by weight loss, chronic diarrhea, vomiting, excessive thirst/urination, a pot-bellied appearance, or lethargy. These are red flags for malabsorption syndromes, parasitic burdens, or endocrine disease that require prompt treatment.

How to Get Your Dog to Stop Eating Poop: A Step-by-Step Framework

Once medical causes are ruled out or treated, you can tackle coprophagia as a behavioral problem. Here is the framework I recommend based on years of working with dog owners and certified trainers. This is a layered approach — start at Step 1 and add layers as needed.

Step 1: Environmental Management (Immediate)

Management is not a permanent fix, but it breaks the reinforcement cycle. Every time your dog successfully eats stool, the behavior is rewarded (the taste, the crunch, the attention). You must interrupt that cycle.

• Pick up feces within 60 seconds of defecation in your yard. Use a dedicated pooper-scooper — the Four Paws Wee-Wee Scooper ($12–$18) works well for small yards, while the Arm & Hammer Swivel Bin & Rake ($22–$30) handles larger properties.
• Leash your dog during potty breaks so you can guide them away immediately after they finish. A 4- to 6-foot leash gives you better control than a retractable.
• Teach a "leave it" cue using positive reinforcement. Start with low-value items on the ground (kibble pieces), reward with a higher-value treat from your hand, and gradually work up to practicing near feces (use fake setups with peanut butter on a paper towel).
• Supervise multi-pet households. If you have a cat, the litter box is a coprophagia buffet. Use a top-entry litter box like the Modkat Flip ($65–$80) or install a baby gate with a cat-sized opening to restrict dog access.

Step 2: Dietary Adjustments

Nutritional gaps can drive stool-eating. Even dogs on premium kibble may have individual absorption issues. Consider these evidence-based adjustments:

• Verify AAFCO compliance: Your dog's food should carry an AAFCO statement confirming it meets complete and balanced nutrition for their life stage. Check the label for "formulated to meet the nutritional levels established by the AAFCO Dog Food Nutrient Profiles" or "animal feeding tests using AAFCO procedures."
• Increase dietary fiber: Adding 1–2 teaspoons of plain canned pumpkin (not pie filling) per 20 lb of body weight can alter stool consistency and make it less palatable. Pumpkin provides soluble fiber that supports gut health.
• Consider a probiotic supplement: Products like Purina FortiFlora ($28–$35 for 30 packets) or VetriScience Mega Probiotic ($22–$28) can improve digestion and nutrient absorption, reducing the nutritional appeal of feces.
• Feed smaller, more frequent meals: Splitting daily food into 2–3 meals instead of one large meal stabilizes blood sugar and reduces hunger-driven coprophagia.

Step 3: Taste Deterrents (Coprophagia-Specific Products)

These supplements make feces taste unpleasant to dogs. They work by adding compounds (typically monosodium glutamate, yucca schidigera, or bitter extracts) that pass through digestion and alter stool flavor. Effectiveness varies — a study referenced by veterinary behaviorists suggests roughly 50–60% of owners report partial or full improvement.

Important: If you have multiple dogs, ALL dogs in the household need to take the deterrent. If only one dog takes it, their stool becomes unpalatable — but the other dogs' stool remains a target. This is the single most common reason these products "don't work."

Step 4: Behavioral Training & Enrichment

Boredom and anxiety are major coprophagia triggers, especially in high-energy breeds and working-line dogs. Address the root cause:

• Increase daily mental stimulation: Replace 15–20 minutes of walk time with structured enrichment — snuffle mats ($15–$35), frozen KONG toys stuffed with peanut butter and kibble, or scent-work games. Mental fatigue reduces compulsive behaviors more effectively than physical exercise alone.
• Practice the "come away" recall after pottying: Immediately after your dog defecates, call them to you with an enthusiastic cue and reward with a high-value treat (freeze-dried liver, small cheese pieces). This builds a habit of moving away from the spot rather than lingering.
• Never punish after the fact. Rubbing a dog's nose in feces or yelling after they've already eaten it does not teach them anything — it teaches them to fear you and may actually increase coprophagia (they eat the evidence faster next time). Use only positive reinforcement and management.
• Address separation anxiety if present: Dogs with separation anxiety often engage in compulsive behaviors when left alone, including coprophagia. If your dog shows signs like destructive behavior, excessive vocalization, or inappropriate elimination when alone, consult a certified veterinary behaviorist (find one through the American College of Veterinary Behaviorists).

Puppy Coprophagia vs. Adult-Onset: What's Different

The approach to stopping coprophagia depends heavily on your dog's age and when the behavior started.

Puppies (Under 12 Months)

Puppy coprophagia is extremely common and often self-resolving. Mother dogs naturally eat their puppies' feces during the first few weeks to keep the den clean, and puppies may mimic this behavior. Most puppies outgrow it by 9–12 months with consistent management. Your priorities:

• Supervise all potty breaks and redirect immediately
• Ensure the puppy is on a high-quality, age-appropriate diet (puppy-formulated, AAFCO-certified for growth)
• Rule out parasites — puppies are especially prone to roundworms and hookworms, which cause nutrient deficiencies
• Be patient: this is developmental, not defiance

Adult Dogs (Over 1 Year)

New-onset coprophagia in an adult dog is more likely to have a medical component. Prioritize the veterinary workup described above. If medical causes are ruled out, focus on enrichment, dietary adjustments, and taste deterrents. Adult-onset coprophagia that persists beyond 4–6 weeks of consistent management warrants a referral to a veterinary behaviorist.

How Long Does It Take to Stop Coprophagia?

There is no single timeline, but here is what to realistically expect based on the intervention layer:

• Environmental management alone: Behavior stops while management is in place but may resume if you lapse. This is a management strategy, not a cure.
• Dietary adjustments + management: Noticeable improvement within 2–4 weeks if nutritional deficiency was the driver.
• Taste deterrents + management: Most products require 2–4 weeks of consistent daily use before you see reliable results. Some dogs never respond to deterrents.
• Full protocol (management + diet + deterrents + enrichment + training): Significant reduction within 4–8 weeks for most dogs. Complete resolution may take 3–6 months, and some dogs require ongoing management indefinitely.

Consistency is the single biggest predictor of success. One missed potty session where the dog gets to eat stool can undo weeks of progress.

Common Myths About Coprophagia Debunked

There is a lot of bad advice circulating about how to get a dog to stop eating poop. Here are the myths I encounter most often:

Myth: Feeding pineapple or meat tenderizer will stop it.
The theory is that bromelain (in pineapple) or papain (in meat tenderizer) makes stool taste bad. There is no clinical evidence supporting this. Small amounts of fresh pineapple are safe for dogs, but the concentrations needed to alter stool flavor would cause gastrointestinal upset.

Myth: Coprophagia means your dog's diet is low-quality.
>Not necessarily. Dogs on premium, veterinary-recommended diets still develop coprophagia. Individual absorption efficiency, gut microbiome composition, and behavioral factors all play a role independent of food quality.

Myth: Your dog is eating poop to "get back at you."
>Dogs do not engage in revenge behaviors. Coprophagia is not spite — it is a behavior driven by instinct, nutritional need, anxiety, or habit. Anthropomorphizing the motivation leads to punishment-based responses that make the problem worse.

When Coprophagia Becomes a Health Risk

While eating their own stool is generally low-risk for healthy dogs (though certainly unpleasant for owners), certain scenarios carry real health dangers:

If your dog has ingested feces from an unknown or potentially infected source, contact your veterinarian. For suspected toxic ingestion (e.g., manure containing ivermectin), call the ASPCA Animal Poison Control Center at (888) 426-4435 (24/7, consultation fee applies).

Frequently Asked Questions

Can I use hot sauce or cayenne pepper on feces to deter my dog?

This is not recommended. Capsaicin (the compound that makes peppers hot) can cause oral irritation, gastrointestinal inflammation, and eye damage if your dog paws at their face afterward. Commercial taste deterrents formulated for dogs are safer and more effective.

My dog only eats cat poop from the litter box — how do I stop this?

Restrict access first: use a top-entry litter box, place the box behind a baby gate with a cat-sized gap, or install a microchip-activated cat door (such as the SureFlap Microchip Pet Door, $85–$110) that only opens for your cat. Simultaneously, feed your dog a coprophagia deterrent so that any stool they do access tastes unpleasant. Increasing your dog's dietary fiber can also reduce the appeal.

Is coprophagia a sign of a vitamin deficiency?

It can be. Deficiencies in B vitamins (especially B12/cobalamin) and vitamin K are associated with coprophagia, particularly when caused by malabsorption disorders like EPI or inflammatory bowel disease. A veterinary blood panel can confirm or rule out deficiencies.

Will my puppy outgrow eating poop?

Many puppies do stop by 9–12 months, especially with consistent management. However, if the behavior persists past 12 months or intensifies, it is unlikely to resolve on its own and requires active intervention. The longer coprophagia continues, the more ingrained the habit becomes.

Should I switch my dog's food to stop coprophagia?

Sometimes. If your dog's current food is not meeting their individual nutritional needs — even if it is AAFCO-certified — switching to a diet with higher digestibility or a different protein source may help. Discuss the switch with your veterinarian, and transition gradually over 7–10 days (mixing 25% new food with 75% old food for days 1–3, then 50/50 for days 4–6, then 75% new for days 7–9, then 100% new on day 10) to avoid gastrointestinal upset.
