The one true way to determine whether a dog is a bi-color is this: If the proportion of black to tan is exactly the same as it was the day the dog was born, then it is a bi-color. Like Ed Hill said, it is the same color pattern that Dobe and Rotties have. Sue Mazzeo I was having a discussion with someone about what exactly is a bi color. Ok, the dog is mostly black, has a bit of tan on the cheeks, tan on the lower part of the legs but black head. I was told that a true bi color had a grey undercoat. Is that true? Or is there something other I need to be looking for??? The reason is I have a puppy that I personally feel is a very, dark black/tan but someone else says bi.
