Mine was only brushed a couple of times a week and he was fine. The coat on the legs and behind the ears is the only part that ever tangled a little, but even it was fine with just a quick brushing 1-2x's a week.Great pics! I'm going to get a rough collie someday. I've heard conflicting information regarding coat care: Some say you only need to brush them twice a week or so, others say you need to brush them every day or they'll get bad mats. Which is it?
