Why Do Dogs Eat Cat Poop

Dogs are known for their curious and sometimes baffling behaviors, and one of the most perplexing and unpleasant for their owners is their tendency to eat cat poop. While it may seem disgusting to us, this behavior, known as coprophagia, is relatively common among dogs. Understanding why dogs engage in this behavior involves exploring several potential reasons, from instinctual drives to dietary needs and environmental factors.

Hypoallergenic Dogs

1. Instinctual Behavior

Dogs are natural scavengers. In the wild, they would eat a variety of things to survive, including feces. This scavenging behavior is deeply ingrained and can surface even in domesticated dogs. For some dogs, eating cat poop might just be an extension of their instinct to scavenge.

2. Nutritional Deficiencies

One of the primary reasons dogs might eat cat poop is due to nutritional deficiencies. Cat food is richer in protein and fat compared to dog food. This makes cat feces quite appealing to dogs, who may be seeking out those nutrients. If a dog’s diet lacks certain nutrients, they might turn to cat poop as a way to supplement their diet.

3. Taste and Smell

While it might be hard for humans to understand, dogs might actually enjoy the taste and smell of cat poop. Cat feces often contain undigested food particles that still smell like the cat food, which can be appealing to dogs. Their strong sense of smell can make them particularly interested in cat litter boxes.

4. Boredom or Anxiety

Dogs that are bored, stressed, or anxious might eat cat poop as a coping mechanism. Engaging in coprophagia can be a way for them to alleviate stress or to pass the time. Dogs left alone for long periods or those without enough physical or mental stimulation are more likely to engage in this behavior.

5. Behavioral Mimicking

Puppies, especially, learn a lot by mimicking their mother’s behavior. If the mother dog engages in coprophagia, her puppies might imitate this behavior. Additionally, puppies often explore the world with their mouths and might eat feces out of curiosity.

6. Attention-Seeking

Sometimes, dogs eat cat poop because they have learned that it gets a strong reaction from their owners. If a dog receives attention (even if it’s negative attention) every time they eat cat poop, they might continue to do it as a way to interact with their owner.

7. Medical Conditions

Certain medical conditions can lead to coprophagia. For instance, dogs with malabsorption syndromes, parasitic infections, or other gastrointestinal issues may eat feces due to increased hunger or because they are not absorbing enough nutrients from their food. Thyroid disease and diabetes can also cause an increase in appetite, leading to coprophagia.

Preventing Coprophagia

While understanding why dogs eat cat poop is important, preventing this behavior is equally crucial for maintaining a healthy and clean environment. Here are some strategies to prevent dogs from indulging in this habit:

1. Diet and Nutrition

Ensure your dog is getting a balanced diet with all the necessary nutrients. Consult with your veterinarian to determine if your dog’s diet needs any adjustments. Sometimes, adding enzyme supplements can help with nutrient absorption.

2. Training and Supervision

Training your dog to understand commands like “leave it” can be very effective. Supervising your dog’s interactions with the litter box and redirecting their attention with toys or treats can also help.

3. Environmental Management

Keep the litter box out of reach of your dog. Place it in a location that is accessible to your cat but not to your dog, such as behind a baby gate or in a high place. Using a covered litter box can also reduce your dog’s access.

4. Increase Physical and Mental Stimulation

Ensure your dog gets plenty of exercise and mental stimulation. Regular walks, playtime, and interactive toys can help alleviate boredom and anxiety, reducing the likelihood of coprophagia.

5. Cleanliness

Regularly clean the litter box to remove feces promptly. The less time feces are available, the less opportunity your dog has to eat it.

6. Veterinary Check-Up

If your dog’s coprophagia persists, it’s essential to have them checked by a veterinarian to rule out any underlying medical conditions that might be contributing to the behavior.


While the behavior of eating cat poop is undoubtedly unpleasant, understanding the underlying reasons can help pet owners address and prevent it. Whether driven by instinct, nutritional needs, or environmental factors, coprophagia can often be managed through proper diet, training, and environmental adjustments. By taking proactive steps, pet owners can reduce the chances of their dogs indulging in this habit and maintain a healthier, more harmonious home.
