So since Diane recently saved my long coat girls from their coat mats, I have to respond. I never stopped to think about how getting wet and dry through out the day would mess up their coats. We have a pond, Tessa (9) had rolled awkwardly chasing a ball. I decided fetch in the pond was a answer. Certainly helped her aches and matted her coat quickly and badly. Thanks to Diane I bought a dog hair dryer good leave in conditioner and a better brush. So everyone gets dried if they swim. I still had to cut some bad mats out but what a difference. I also watched a video she recommended on better brushing techniques. Thanks again, Diane.
