Black stool in any animal can be a sign of blood in the stool. I would get it checked out by a vet ASAP as it can mean internal bleeding or an ulcer. Black stools (in any animal) are a sign of Iron or blood in the stool. Your dog is bleeding, take them to the vet.
When stool is black, that means that the bleeding has not occurred in your rectum, large bowel or anus, which are parts of the lower GI tract. It is also means that it is not hemorrhoidal bleeding, which is generally quite red and fresh.
