Black poop can be caused by something he ate, digested blood, and sometimes pepto bismol. I would watch closely for any nausea, vomiting, diarrhea, or another black stool. If any of these occur then he should be evaluated by a veterinarian as soon as possible. Best of luck and thank you for using Pet Coach.
