Why do dogs eat eat their own poop

Your dog eats his own poop possibly because he is hungry, he is bored, or he may be lacking vitamins in his diet. ChaCha!

Your dog may be eating too fast and thus causing it's food not to digest enough, so he can still smell what he ate in the pile.

According to Dr. Jo Ann Eurell, "Dogs are historically scavengers, and this is believed to be a scavenger behavior." ChaCha!
