I was always brushing and combing Azrael since her hair is so thick and it also matts easily, till I started doing a hot oil treatment on her and Zada due to the dry winter air that causes itchy's. Well it works like a charm. Her hair is soft and she isn't matting. I use All Systems shampoo, and was using the conditioner as well.
(they also get cod liver oil every day for skin and coat)
