Report Abuse. Usually a dog who has black stool is not getting the right kind of food because they tend to go eatting from the wrong sources. I had a dog(short haired) collie who had this problem.

Certain foods can cause black stools. But if this is a consistent feature, you need to get checked. Usually black stools are caused by bleeding up higher in the GI tract. There is a bleed, the gut breaks down the red blood cells, and the iron reacts to make the black stool. This is a very very serious symptom. You need immediate assessment.
