I would be concerned about your puppy as well! His poop looks very dark, and the color could be due to bleeding from the upper GI tract. This bleeding could be used by eating something toxic, a foreign body, trauma to the GI tract, or hemorrhagic gastroenteritis among other causes. When a puppy has been pooping dark feces for a couple of days, it's time to see the vet. The vet can diagnose what is causing his symptoms so he can be treated. Please take him into a vet now.
