my 5 mo. old beagle eats poop also. the vet said this is a "behavior". which means it can be unlearned. training and discipline should stop this behavior. pick up poop asap, say "no", etc. Tried potty mouth pills...didn't work. so far, discipline and picking up poop right away seem to be the best cure so far. supposedly some dogs will also just grow out of this behavior, but i wouldn't count on it.
