Warm winter fleece and waterproof dog coats for small, medium and large dogs. Our coats fit normal to full chested breeds well. Easy velcro closures. Washable. We size our coats in inches for easy fitting. Just measure your dog from the neck, where the collar sits to the base of the tail. Round up to the next even size if the measurement is in between sizes. A lot of people don't realize that many smaller dog breeds have hair and not fur with an undercoat to keep them warm and dry.
