How to Stop Dog From Eating Poop: Home Remedies & Vet-Backed Fixes

Coprophagia — the clinical term for stool eating — is one of the most unsettling habits a dog owner can witness. If you've ever turned around on a walk to find your dog happily snacking on feces, you're not alone. A 2018 study presented at the American Veterinary Society of Animal Behavior found that roughly 25% of dogs exhibit coprophagic behavior at some point. The good news? Most cases can be resolved with the right combination of home remedies, management strategies, and behavioral training.

This guide covers every evidence-based method to stop your dog from eating poop, from dietary tweaks and over-the-counter deterrents to positive reinforcement training protocols. We'll also explain why dogs do this in the first place, because understanding the root cause is essential to choosing the right fix.

Why Do Dogs Eat Poop? Understanding the Root Causes

Before reaching for a remedy, it's worth identifying which type of coprophagia your dog exhibits. The motivation matters because it determines which solutions will actually work.

Behavioral Causes

• Attention-seeking: Your dog learns that eating poop gets a dramatic reaction from you (even yelling counts as attention).
• Boredom or under-stimulation: Dogs with insufficient mental and physical enrichment may turn to stool eating as a self-rewarding activity.
• Den-cleaning instinct: Nursing dams naturally consume puppy feces to keep the whelping area clean. Some dogs retain this behavior.
• Anxiety or stress: Dogs in high-stress environments (shelters, multi-dog households with competition) may eat feces as a displacement behavior.
• Learned behavior from other dogs: Coprophagia can spread socially in multi-dog homes — one dog starts, others follow.

Medical & Nutritional Causes

• Intestinal parasites: Roundworms, hookworms, and giardia compete for nutrients, potentially driving the dog to seek additional food sources including feces.
• Exocrine Pancreatic Insufficiency (EPI): The pancreas fails to produce adequate digestive enzymes, leaving undigested nutrients in the stool that still smell and taste like food to the dog.
• Dietary deficiency or poor-quality food: Diets lacking sufficient fiber, B-vitamins, or digestible protein may produce stool that still contains appealing nutrients.
• Cushing's disease or diabetes: Conditions causing polyphagia (excessive hunger) can drive dogs to eat anything available, including feces.
• Malabsorption syndromes: Inflammatory bowel disease or food allergies can prevent proper nutrient absorption.

Key insight from veterinary behaviorists: Dogs that eat their own stool often have a different underlying cause than dogs that eat other dogs' or cat feces. Cat feces are particularly attractive to dogs because cat food is high in protein and fat, and the resulting stool retains a strong food-like odor. This is sometimes called "the kitty litter buffet" problem.

Home Remedies That Actually Work (And Which Ones Don't)

Not all home remedies for coprophagia are created equal. Here's a breakdown organized by evidence strength and practical effectiveness.

Dietary Adjustments

Taste-Aversion Products (Over-the-Counter Stool Deterrents)

These products work by making the dog's own stool taste unpleasant after ingestion. They're most effective for dogs eating their own feces, not those scavenging other animals' stool.

• For-Bid (by VETRISCIENCE): Contains wheat gluten, sodium glutamate, and garlic powder. Sprinkled on food for 5-6 days. Priced around $12-$18 for a 60-day supply.
• Coprophagia Deterrent by NaturVet: Contains Yucca schidigera extract, garlic, and parsley. Chewable tablets, approximately $10-$15 for 60 chews.
• Deter (by Lambert Kay): Methylcellulose-based, creates unpleasant stool taste. Approximately $8-$12.
• Prozyme Coprophagia Deterrent: Enzyme-based powder, around $15-$22.

Remedies to Avoid

Training Protocols to Stop Coprophagia

Home remedies address the dietary side, but behavioral modification is often the most reliable long-term solution — especially for dogs that eat other animals' feces or stool they find on walks.

The "Leave It" Command Protocol

This is the foundational skill for coprophagia management. Use positive reinforcement exclusively — no aversive tools like shock collars or prong collars.

1. Stage 1 — Indoor setup (Days 1-5): Place a low-value treat on the floor. As your dog approaches, say "leave it" in a calm, neutral tone. When they look away or back at you, immediately mark with a clicker or "yes!" and reward with a higher-value treat from your hand. Repeat 10-15 times per session, 2-3 sessions daily.
2. Stage 2 — Increase difficulty (Days 6-12): Use higher-value items on the floor. Practice in different rooms. Begin adding distance — say "leave it" when you're 6-10 feet away from the item.
3. Stage 3 — Outdoor generalization (Days 13-21): Practice on leash in your yard. Plant fake "poop" (use a small piece of brown dog-safe material or a dried treat your dog doesn't love). Reward heavily for compliance.
4. Stage 4 — Real-world application (Ongoing): On walks, scan 10-15 feet ahead for stool. Give "leave it" before your dog notices. Reward with high-value treats (freeze-dried liver, chicken bits). Over time, your dog will begin scanning and avoiding stool independently.

The "Come Away" Recall Method

Teach an emergency recall specifically for situations where you spot feces your dog is heading toward.

• Use a unique cue word you don't use for regular recall (e.g., "here!" or "touch!").
• Practice in low-distraction environments first, always rewarding with the highest-value treat your dog loves.
• Gradually increase distraction level over 3-4 weeks.
• Never punish your dog when they come to you, even if they were heading toward poop.

Management Strategies That Prevent Access

When to See Your Veterinarian About Coprophagia

Diagnostic Tests Your Vet May Run

If you bring coprophagia to your veterinarian's attention, expect some or all of the following workup:

• Fecal flotation and Giardia antigen test: $35-$65. Rules out intestinal parasites that cause nutrient malabsorption.
• Complete blood count (CBC) and chemistry panel: $80-$180. Screens for metabolic conditions like diabetes, Cushing's disease, or liver dysfunction.
• Trypsin-like immunoreactivity (TLI) test: $60-$120. Screens for Exocrine Pancreatic Insufficiency, a leading medical cause of coprophagia.
• Cobalamin (B12) and folate levels: $50-$90. Assesses intestinal absorption function.
• Dietary review: Your vet will assess whether your dog's current food meets WSAVA Global Nutrition Committee standards for complete and balanced nutrition.

Preventing Coprophagia Long-Term

Once you've stopped the behavior, preventing relapse requires ongoing management. Here's a practical maintenance checklist:

Daily Habits

• Pick up yard feces at least once daily — twice daily if you have multiple dogs.
• Feed a nutritionally complete diet meeting FDA safety guidelines for pet food.
• Provide 30-60 minutes of structured exercise and 15-20 minutes of mental enrichment (puzzle toys, snuffle mats, training sessions) daily to reduce boredom-driven coprophagia.
• Keep litter boxes inaccessible to dogs — this is the single most effective change for cat-owning dog households.

Monthly Maintenance

• Administer monthly heartworm/intestinal parasite prevention (e.g., Heartgard Plus, Interceptor Plus, or Simparica Trio — $18-$25/month depending on dog weight).
• Submit a fecal sample to your vet every 6-12 months for parasite screening, even if your dog is on preventive medication.
• Reassess your dog's body condition score (BCS) — a score of 4-5 on the 9-point Purina scale indicates ideal weight. Overweight or underweight dogs may have nutritional imbalances driving coprophagia.

Multi-Dog Household Specifics

If one dog in a multi-dog home eats stool, the behavior often spreads. Address it immediately:

• Supervise all bathroom breaks until the habit is broken.
• Feed dogs separately to reduce food competition anxiety.
• Consider treating all dogs with a stool deterrent product simultaneously, even if only one exhibits the behavior.
• Ensure each dog has their own feeding station, water bowl, and resting area to reduce resource-guarding stress that can trigger displacement behaviors like coprophagia.

How Long Does It Take to Stop a Dog From Eating Poop?

Realistic timelines vary based on the underlying cause and consistency of your approach:

Frequently Asked Questions

Is it harmful for my dog to eat poop?

While coprophagia is generally not life-threatening, it carries real risks. Dogs that eat feces can contract intestinal parasites (roundworms, whipworms, hookworms), bacterial infections (Salmonella, E. coli), and viral diseases (parvovirus can survive in feces for months in the environment). There's also a zoonotic risk — dogs that eat feces and then lick humans can transmit parasites like Toxocara canis (roundworm), which can cause visceral larva migrans in people, particularly children.

Will apple cider vinegar stop my dog from eating poop?

There's no strong veterinary evidence supporting apple cider vinegar as a coprophagia deterrent. While some owners report success adding 1 teaspoon per 20 lb of body weight to meals, the mechanism is unclear and results are inconsistent. ACV in excessive amounts can also cause GI upset or erode tooth enamel. If you try it, use raw, unfiltered ACV (like Bragg's, $6-$10) at the dose above and discontinue if your dog shows signs of stomach discomfort.

Why does my dog eat cat poop but not dog poop?

Cat feces are particularly appealing to dogs because cat food is higher in protein and fat than dog food, and cats have shorter digestive tracts. This means cat stool retains more undigested nutrients and a stronger food-like odor. The solution is environmental management — use a top-entry litter box, place the box behind a pet gate with a cat-sized gap, or install a microchip-activated cat door that excludes the dog.

Can puppies grow out of eating poop?

Some puppies do stop coprophagia as they mature, particularly if the behavior is related to exploratory mouthing (common in puppies 2-6 months old). However, the Merck Veterinary Manual notes that coprophagia that persists beyond 6-9 months of age is more likely to become a fixed habit requiring active intervention. Don't wait and hope — start management and training early.

Should I use a muzzle to stop my dog from eating poop on walks?

A basket muzzle (like the Baskerville Ultra or Jafco muzzle) is a safe, humane management tool for chronic coprophagic dogs on walks. It prevents stool eating while allowing your dog to pant, drink water, and take treats through the front opening. Muzzle conditioning should take 5-7 days of positive reinforcement training before use — never force a muzzle on an unprepared dog. Muzzles are a management tool, not a cure, so continue training the "leave it" command alongside muzzle use.

My dog only eats poop when I'm not watching — what can I do?

This suggests the behavior is attention-motivated or that your dog has learned to avoid doing it in front of you (which actually means they understand it's unwanted). Solutions include: installing a pet camera (Wyze Cam v4, around $35-$50) to monitor yard time, keeping your dog on a long line during bathroom breaks, and picking up feces immediately. The key is removing the opportunity entirely for 4-8 weeks while the habit extinguishes.
