Ok not too long ago I heard of a red legged yorkie which most of the times has coarse/wire silk coat. Their body temp. is usually lower than normal and they have a deeper red color to them. Breeders usually use these yorkies to get better colors in their lines. The hair on their legs and face I believe never gets long like a true silk yorkie. To me (JMHO) this is a true full blooded yorkie and he seems to fit the characteristics of a red-legged yorkie. I will google and find out more!!!
