Is it harmful for a dog to eat its own poop?

It is harmful for a dog to eat its own poop. First, a dog’s feces carry many bacteria and may have parasites, so eating them easily causes stomach upset.

Second, once a dog gets used to eating poop it may move on to other dogs’ or cats’ waste; if the other animal carries parasites or a viral disease, it can also harm your dog. So the owner should try to stop the dog from eating poop, feeding it on a fixed schedule and amount to avoid hunger-driven coprophagia. Also, take the dog to a vet for a check; if the coprophagia comes from a lack of trace minerals (pica), adjust the diet and give complete nutrition in time.
