Royal Canin Skin & Coat Health Supplement Soft Chews support healthy skin and a glossy coat for adult dogs. Developed by veterinarians, these chews provide a science-driven blend that includes Omega-6 fatty acids (GLA) and Zinc to hydrate the skin and promote coat quality, plus Omega-3 fatty acids (EPA/DHA) and a B-Vitamin blend to support the skin barrier. Designed to complement any Royal Canin diet, be sure to follow the on-pack feeding guidelines and give your dog no more than the recommended number of pieces per day.
