I am not a professional but black stool in canines can mean, change in diet(with dark kibbles), blood in large intestine,worms of some kind, poisons, poisonous plants or stomach ulcer. My Dog has recently went through a bleeding stool now to a dark stool , yet not always. I shall be taking her back to the vet on Saturday with another stool sample. I suggest if you notice anything different in your pet you should take them to the vet right away!
