I went to Pet Supplies Plus and purchased a very small comb. It is probably no more than 4 inches long and is made by Lil'l Pals. It has very thin, close together teeth on one side and a little wider teeth on the other. It is totally awesome on LuLu. I hold the matted area underneath and work with it, so it doesn't pull her skin. Also, I purchased (from Walmart) Hartz Infusions Conditioning Spray. It moisturizes and detangles and does not require rinsing. It also has an Ocean Mist scent. Since I started using these items, LuLu very seldom gets any mats anymore. Good Luck!
