Dog Eating Poop: Why It Happens and How to Stop It

Finding out your dog eats feces is unsettling. Yet coprophagia — the scientific term for stool-eating — affects 16–24% of dogs at some point in their lives. It has real causes, and real solutions. Here's what you need to know.

Why Do Dogs Eat Poop?

Medical Causes

• Exocrine Pancreatic Insufficiency (EPI): The pancreas doesn't produce enough digestive enzymes. The dog is chronically undernourished despite eating plenty.
• Malabsorption disorders: Inflammatory bowel disease and similar conditions prevent nutrients from being absorbed.
• Intestinal parasites: Worms compete for nutrients, leaving the dog nutrient-deficient.
• Low-quality diet: Cheap kibble doesn't deliver adequate bioavailable nutrition.
• Chronic hunger: Portions too small or feeding times too spread out.

Behavioral Causes

• Maternal instinct copied: Mother dogs clean up after puppies by eating their feces — puppies may imitate this.
• Boredom: A mentally and physically understimulated dog will find its own entertainment.
• Anxiety: Separation anxiety and confinement stress trigger repetitive behaviors, including coprophagia.
• Hiding the evidence: Dogs punished for indoor accidents learn to eat the proof.
• Attention-seeking: If you react dramatically, the dog learns that eating poop gets a response.
• Puppy exploration: Puppies use their mouths to explore everything; most grow out of this naturally.

Environmental Causes

• Access to cat feces (high in protein, very appealing to dogs)
• Other dogs' feces in the yard or at the park
• Lack of outdoor space and exercise

When to See the Vet

Rule out medical causes first if:

• The behavior started suddenly in an adult dog with no prior history
• Accompanied by weight loss, chronic diarrhea, or vomiting
• Your dog primarily eats their own feces (self-directed — stronger indicator of malabsorption)

A fecal exam for parasites and a blood panel to check for EPI are typically the first steps.

How to Stop It

Environmental Management — the Most Effective Tool

• Pick up immediately: No feces = no coprophagia. Simple and fast.
• Keep the cat litter box behind a closed door or use a covered box.
• Supervise all outdoor time until the behavior stops.

Improve the Diet

• Switch to a high-quality complete and balanced food.
• Split daily food into 2–3 meals to prevent hunger gaps.
• If EPI is diagnosed, enzyme supplements are transformative.

Exercise and Enrichment

• Increase walk duration and intensity.
• Add mental enrichment: snuffle mats, puzzle feeders, nose work games, Kongs.
• A tired, engaged dog doesn't have the bandwidth for problem behaviors.

Training

• Teach a solid "leave it" with positive reinforcement — then apply it consistently outdoors.
• Don't punish or react loudly — that's just attention, which reinforces the behavior.
• Redirect to an incompatible behavior (sit, watch me) whenever you see interest in feces.

Commercial Deterrents

Products that make feces unpalatable exist (For-Bid, pineapple supplements, etc.). Results vary. They don't address the root cause — treat them as a last resort, not a first step.

Timeline

With consistent environmental management and the underlying cause resolved, most dogs improve within 4–8 weeks. Without removing access to feces, no training approach will work reliably.

Frequently Asked Questions

Is it normal for puppies to eat poop?

Yes — it's common in puppies under 6 months. Most grow out of it. If it persists past 6 months, address it actively.

My dog only eats other dogs' poop, not their own. Is that different?

It's usually more behavioral than medical in that case. Management (pick up immediately, use "leave it") is the primary solution.

Will it ever stop on its own?

Puppy coprophagia often does. In adults, it rarely resolves without intervention — especially if the habit is established.
