Ok, so my Riley is blowing his coat and I've managed to help it along with frequent line brushing. However, his undercoat just doesn't seem to release the same around his mane. We had the same problem last year and I took him to a professional groomer who also breeds shelties. She did a marvelous job and the undercoat was all gone when I came back just 90 minutes later. Question: how do breeders and groomers get it out so well? Is it the professional combs and rakes? I can't figure this out. I have given him a bath with furminator shampoo and conditioners that are supposed to release the undercoat and used the high velocity dryer at the dog wash. I line brushed and raked and still his undercoat around his neck remains much thicker than anywhere else. It's getting quite warm in the Okanagan and he is starting to feel the heat. I would like to help this along as much as I can. Any advice?
