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.
This type of dog blood in stool may also result from ingestion of blood. For example, your dog may have licked a bloody wound or he may have had a mouth injury causing him to swallow blood. The partially digested blood turns the stools to black and tarry.
