Why do puppies eat their feces?

Answer 1

A dog will eat its own feces if it is still hungry or lacking nutrients because feces can still contain some nutrients, but extremely little, and its own feces is another source they know is safe to eat because hyenas drink their own urine during a drought to prevent dehydration. It is a survival instinct.

Answer 2

because they are not getting enough nutrients in their food =Answer= The jury is still out on this one. The most popular belief is the one the other poster gave, but it's a limp answer to the reality of the question. At the beginning dogs were wild (until tamed by man) and they did all sorts of things to survive. I've heard that dogs often ate feces to cover up where that particular pack of dogs had been. There is no proven theory that either of these answers are correct.

Answer 3

Dogs will eat almost anything. Part of coprophagia (feces eating) in dogs comes from their instincts. They have some instinctual drives toward hygiene. A mother dog will lick her puppies in their anuses to help stimulate their bowels. She may also eat anything that she sees as a risk to her puppies. Then after a while, it can become a habit, where she will clean up after unrelated dogs and other animals.
