Hi I'm new to YT-Hello All. I have a little 2.5lb. parti yorkie she is 4mo. old. She has thin hair & I have been giving her (solid gold) seameal-read on here helps with hair growth, now I see -1" hair where the hair parts down her back. On her body the coat is about 5-6".. I am trying to figure out if this I am seeing new hair growing in starting in the part or am I seeing hair breakage or is she losing hair (although I have not seen any shedding or hair anywhere) the 1" hair is mainly down the part of the back is this normal??? Help
