Oh my God, I came home from NY yesterday, and my Cody was so excited to see me!!! He was left behind with my kids and mom. Anyway, I noticed a few weeks back that the roots on the top of his head are coming in gray. Normal right? Well, I am now noticing that his hair on the top of his head, right smack in between his ears, looks awfully thin and looks like it is balding, his scalp is clearly visible, scalp looks normal, he doesnt scratch, what could be the cause? Please help.
