Royal Canin Pug Adult's exclusive formula helps to support the skin's “barrier” role, as well as overall skin health for your Pug. Royal Canin Pug Adult also contains a balance of nutrients that help to support your Pug's muscle tone. Pugs have very specific features: a large head and a body with short, square muscles. Its jaws and very thick lips can make it difficult for it to pick up its food. However, with an exclusive kibble design, Royal Canin Pug Adult makes it easier for the Pug to pick up and to encourage him to chew.
