Why Does My Dog Eat Poop? (Coprophagia Explained)

How Common Is Coprophagia?

More common than most owners realize. A landmark study found that approximately 24% of dogs have been observed eating feces at least once, and 16% are "serious" poop eaters (caught 5+ times).

Why Dogs Eat Poop

The causes fall into behavioral and medical categories:

• Maternal instinct — mother dogs eat puppy feces to keep the den clean. Some dogs retain this behavior.
• Attention-seeking — dogs learn that eating poop gets a dramatic reaction from owners.
• Boredom or anxiety — dogs with insufficient mental stimulation or separation anxiety.
• Learned behavior — puppies see other dogs doing it and mimic.
• Nutritional deficiency — rare, but enzyme deficiencies or malabsorption can drive poop eating.
• Enzyme insufficiency (EPI) — undigested nutrients in stool make it "appetizing" to dogs.
• Overfeeding — excess food in stool from overfeeding or low-quality food.
• Punishment-based potty training — dogs learn to "hide the evidence."

Health Risks

• Parasite transmission — consuming feces from infected dogs spreads roundworms, hookworms, giardia, and coccidia.
• Bacterial infections — salmonella, E. coli, and Clostridium can be transmitted.
• Viral transmission — parvovirus spreads through fecal-oral route.
• Chemical exposure — if the eaten feces contain medications or supplements.
• Reinfection — a dewormed dog eating its own contaminated stool can reinfect itself.

How to Stop It

1. Remove temptation — pick up all feces immediately. This is the #1 most effective strategy.
2. Supervise outdoor time — go outside with your dog and redirect before they reach a pile.
3. Train "leave it" — a strong leave-it command gives you a tool to interrupt the behavior.
4. Increase exercise and enrichment — puzzle toys, training sessions, and play reduce boredom-driven eating.
5. Add enzyme supplements — products like Forbid or For-Bid make stool taste unpleasant (though success rates vary).
6. Rule out medical causes — have your vet check for EPI, malabsorption, or nutritional deficiency.
7. Do not punish — yelling or rubbing their nose in it makes the problem worse, not better.

Breeds More Prone to Coprophagia

• Labrador Retrievers — the breed most commonly cited in studies.
• Beagles — food-motivated and eat nearly anything.
• Shih Tzus — the breed with the highest coprophagia rates in some research.
• Golden Retrievers — oral fixation and food motivation.
• Shetland Sheepdogs — some studies note higher rates.
