When mine get a matted area, I spray with a detangler and use a fine tooth metal comb. You will have to take one small section at a time. It is time consuming and you have to be careful not to hurt them, I always keep my fingers between the skin and the matt. If she is matted all over you may come out better taking her in to have her done or cut.
I learned the hard way to brush them everyday. I had to cut Tonee once and I hated it.
