My male dog was neutered at 6 months. He has been eating feces ever since then. It is the most disgusting thing I have ever seen, and I have to be honest - it makes me not want to keep him. We have a female (also fixed) that we purchased at the same time - they have been raised together as "brother & sister." He eats her feces, he eats his feces. Fresh, dry, coming out of her bum, it doesn't matter. It is as if he has a mineral definiency and is somehow seeking out the nutrients in the feces - but thing of it is that there is no decifiency. He is a healthy dog. Any other suggestions?
