The Lycra Bodysuit is great for keeping wavy coats flat in breeds like Golden Retrievers, Irish Setters, English Setters, and Labradors. The Lycra stretches so much that you can get a snug fit to flatten the coat while still maintaining the comfort and flexibility your dog deserves. Because the bodysuit does flatten the dogs coat, we do not recommend using the Lycra K9 Top Coat on a full coated dogs such as Collies, Keeshonds, or Shelties during a show weekend. However, the Lycra Bodysuit works great to keep these long coats protected at home.
