Red Yorkshire Terrier. Red Yorkshire Terriers, or sometimes Red-Legged Yorkies, are another variant of the breed. Again, the red (think bronze) coloring comes from the phaeomelanin gene, which is the same gene component that gives us the Golden Yorkie, only a greater abundance of the melanin makes the hair appear darker. This is more common on the underside of the dog, especially around the chin, chest, and legs.
