The last time I brought Macy in they did the same thing to her- that was about 2 months ago. Her coloring is still a lot grey and no black! But she is starting to look cute again not like a nakid molerat!
It is hair and it will grow back but at the time I just wanted to shave the groomer bald also!
But you still have your baby to hold and now you just have to keep him warm!
