I have a black female, she comes from a litter of all blacks and her breeder has several black dogs in her program. Her dam is all black and the sire is a very dark bi color, all black except some tan speckling on his legs.
My girl has tan between her toes and some random white fur on the inside of her back legs and on the underside of her tail. When she was very young, my male closed her little bitey mouth so for a long time she had 2 white slashes across her nose.
The breeder said sometimes a deep cut will come back white on a black dog. With seasonal molting, the white on her nose is fading but it's moving over to her legs I guess.

I have duct tape and I am not afraid to use it.
