Why does my dog eat his own poop?

Sometimes a dog will eat their own poop because it smells like the dog food they eat. It is important to take your pet to vet to rule out any medical problems.

Dogs can eat poop (coprophagy), for an attention getting behavior from the owner. Anxiety, stress, frustration, and boredom can be another cause. Also a dog may eat poop to immitate the owner picking up feces. Rule out a medical cause for poop eating with a check up from a veterinarian.

Sometimes they are missing a nutrient they are not getting in their food. Ask the vet, I am sure its a common question

One of the foster PBTs I host currently is a poo-eater. She was being starved by "owner," so I thought that was the cause - food insecurity - which may contribute. But like most things, there are other variables relative to causality and correlation that explains. For example, if I mix bone broth or chicken broth with their dog food, it makes the poop irresistible in taste so I quit doing that! I also began giving her lunch in between breakfast and dinner and then also a snack around 8 pm which helped tremendously. Low calorie so she doesn't gain weight. It's hard being a dog; they are essentially our captives and in some cases unfortunate prisoners, and we take away their freedom to seek food or water, sun or shade, the outdoors or in a cave, migration 8 hours a day is what they want and we take that away. I do not shame her if I see her eating poop, but sometimes I impulsively yell her name (bec seeing it causes me an impulsive revolting experience in my physiology) and I need to be more watchful of when she is approaching poop so that I can divert her path and distract her. We also switched her food, we upgraded it to a high-end human-grade dog food. We dramatically reduced her poo eating. Good luck.
