Two of my girls who will turn 2 in November have lots of hair mostly from her middle to the tail and it is wavy(unfortunately it hard to brush and gets knotted often) but their dad is small and pure bred from a known breeder in Miami. One of them has curly hair on top of her head also, they are black, silver and have beige legs. Very cute and I guess it is normal in some yorkies. Anyway I love them as much as my other babies.
