This brush works really well on Bogie my biewer guy's cotton coat.
Amazon.com: Isinis Hair Brush * Made In France:... and I use the green Madan pin brush also. I kept him in a long coat for over a year, and to keep the mats at bay was such a long tedious task. I cut him into a puppy cut in Dec. leaving his legs and face long. I was also using the ISB product line including the PEK conditioner and their products work great, but they are really expensive. My DH would kill me if he knew how much I spent on those grooming products.
Here are a couple of pics...one in full coat and one in the cut I currently have Bogie in. Good luck
