my 9 month old yorkie's fur is really matted up, ive tried to comb her out but the matts are pretty big, when i try to comb her she yelps. I was try to let her fur grow out a bit since her groomer shaved her when she was younger, and i really dont want to do that again, plus she has allergies to alot of different shampoos. Any suggestions for a good brush or comb or even some different shampoo, I would really appreciate. Thanks

Gracie and
