I would like to show you my dog in his new K9 top coat, we use it so he can swim with us and not shed all over the pool. ( we also put the funny life vest on him, as he gets tired swimming so much but wont come out of the pool) its also light gray and keeps him cooler in the sun. he is a black GSD. we followed the sizing on your site and it fits to a T! he loves getting into it, its easy to use, easy to get on and off, and he really does want to wear it, maybe cause that means swim time but… I am sure he will love it in winter too to keep ice off his fur. very happy with the product. this is my second dog to own a K9 top coat.
