Is It Common for Dogs to Eat Their Own Feces?

Why Do Dogs Eat Their Own Poop?

Coprophagia, or the act of eating feces, is a widespread behavior in dogs and is considered normal by many experts. Mother dogs naturally eat their puppies’ excrement to maintain a clean and safe den, reducing the risk of attracting predators. Puppies often observe this behavior and may mimic it, turning it into a lifelong habit. This instinctual act is rooted in a dog’s scavenger ancestry, where eating waste could have provided valuable nutrients in the wild.

The behavior is not limited to puppies—some adult dogs continue it because they find it pleasurable or interesting. Dogs may be drawn to the smell or taste, especially if the stool is from another animal, such as a cat, whose waste is high in protein and thus more appealing.

Common Triggers and Causes

Several factors can contribute to coprophagia. In some cases, it’s a learned behavior—dogs may copy others or be unintentionally rewarded by human reactions, such as being scolded or cleaned up after defecating. One case described a dog that learned to hide its waste after being punished for toileting indoors, showing that fear or punishment can reinforce the habit.

Boredom and lack of mental stimulation are also common causes, especially in dogs from puppy mills or pet stores who grow up in isolation with little to entertain them. For these dogs, feces may become a form of play or a way to pass time.

When It Might Be a Concern

While coprophagia is often normal, it can become problematic if it’s excessive or obsessive. Dogs that defecate multiple times a day and immediately eat their waste may be showing signs of obsessive-compulsive disorder (OCD). In such cases, professional help from a veterinarian or dog behavior consultant is recommended.

Health risks are also a concern. Eating feces—especially from other animals—can expose dogs to intestinal parasites, bacteria, or infectious diseases. This risk can extend to humans, particularly if the dog licks them after eating waste.

How to Manage and Stop the Behavior

The best way to address coprophagia is prevention. Supervise your dog closely when outside and pick up waste immediately. Offering a treat right after your dog defecates can redirect their attention from the stool to something positive.

Training with commands like “leave it” can also be effective. If you catch your dog in the act, interrupt the behavior, redirect their focus, and reward them for obeying. Avoid punishment, as it can worsen the habit or cause fear.

Most Dogs Outgrow It Naturally

Many dogs, especially those under 18 months old, naturally outgrow coprophagia as they mature. However, early intervention through supervision, training, and environmental management can help stop the behavior sooner. With patience and consistency, most dogs can be trained to stop eating feces.
