As a licensed veterinarian practicing in Texas, I’ve seen many cases of dogs eating cat feces—formally known as coprophagia. Although common, this behavior frustrates owners. In my experience, success comes from understanding why it happens and targeting solutions that address the underlying cause. Addressing this issue is possible through clear, focused steps.

Why Dogs Do It

In my experience, dogs aren’t being spiteful or gross on purpose—they’re acting on instinct, curiosity, or learned behavior. Some dogs are drawn to the smell and taste of cat feces, which is often higher in protein than dog stool due to the cat’s carnivorous diet.

I once had a case with a Border Collie named Max, whose owners were at their wits’ end because he would wait near the litter box for any opportunity. Max’s behavior wasn’t due to poor training—it was nutritional curiosity combined with opportunity.

Other times, I’ve noticed that dogs eat cat poop out of boredom or anxiety. I remember a Golden Retriever, Daisy, who developed this habit when her owners had just moved homes, and her routine was disrupted. She wasn’t hungry—she was stressed. That distinction matters because the solution can vary depending on the underlying cause.

Managing Access

One of the most effective ways I’ve helped clients is by controlling access. In Max’s case, we installed a baby gate to block the dog’s access to the litter area while allowing the cat to come and go freely. I also recommended a covered litter box with a flap, which can deter opportunistic dogs rather than obsessive ones.

Changing the location and style of litter boxes also helps. Placing them on elevated surfaces or in restricted rooms often stops the behavior quickly.

Redirection and Training

Even with access control, training and redirection are important. I’ve found that teaching a “leave it” command and rewarding alternative behaviors can gradually reduce the habit. One technique I often suggest is carrying high-value treats and giving immediate positive reinforcement when the dog ignores the litter box. Over time, the dog learns that ignoring the feces yields a reward, while approaching it does not.

Avoid punishment. I saw one client scold her dog, but it only increased anxiety and sneaky behavior. Positive reinforcement works much better, especially with instinctive or stress-based habits.

Dietary Considerations

Coprophagia can sometimes signal a dietary need. In certain cases, reviewing the dog’s nutrition with a veterinarian and making small adjustments, such as improving protein quality or digestibility, can reduce the behavior.

My Professional Take

From my perspective, stopping a dog from eating cat poop requires using a clear combination of environment management, targeted training, and dietary adjustments. With patience and a focused approach, the habit can be eliminated. Stay consistent: observe closely, reward good behavior, and prevent access to the litter box.

Dogs act on instinct, but with practical, consistent strategies, owners can resolve this issue. Focused adjustments—rather than drastic interventions—bring lasting results and restore peace at home.
