Just courious, my Yorki, her name is HazelNut, she is Black and Tan colored, but she has alot of white on her head also, and white on her legs. Would she have a Parti carrier gene? Looking back, when we picked her out, we had traveled 6 hours to get her, were real full of anxiety, and had just lost a pup to unusual circumstances, we looked in the basket full of pups, and they all looked bald! They all actually had white heads. I'm not going to breed her, she is already spayed, just courious about her unusal coloring. When I bought her, I recall the breeder lady saying she had a Chocolate, and never had one that color before, Just wondering. I was so desperate for a pup I would of taken her even if she was bald, she's turned into a very beautiful dog.
