Hello! I have a 14 month male Newf. I'm not exactly sure what's going on with his coat, but he is currently leaving tufts everywhere. And the fur closest to his skin feels much different than the longer fur. Almost like pillow stuffing. Sometimes I think it's matted, but it's not. I know Newfs have a thick undercoat, is that what I'm feeling? And what are these tufts?
