So glad you joined our growing family of Yorkie Lovers!!
Your Cali is adorable. A lot of things go into a good coat - genetics, a good diet, good grooming. You can't do anything about her genetics, but you can help her reach her coat potential by feeding her the best possible diet, doing all you can to keep her healthy and free of parasites, both internal and external (worms and fleas for example), and good consistent grooming practices.
