I have learned recently that genetically sables are sables. Diffrent things control the pigment. "Black sable" is a descriptive term used to describe the depth of pigment on a sable dog. I think its usually associated with sables that carry the recessive black gene. However not all sables that carry black are described as black sable or even dark sable. Its like the Black and red dogs are genetically black and tan. The red pigment is just expressed in a greater amount in the black and red dogs.
