Congrats on your little man starting puberty and marking his turf. The black stool could also be from iron in his diet. You mention that you feed him a homemade diet. If the diet you feed him is high in red meat it could cause the black stool as well. A few times my dogs have had black stool. I has usually been after spending the day with my parents who spoil them rotten. My mother will make steak, and hamburger for the dogs and eat pizza themselves. I would not worry too much about it but check with your vet if it persists. |
