Myth #5: Your dog is born with a certain coat and you can't change its texture, thickness, or glossiness.
Although coat quality is genetic to a large extent, lifestyle can drastically affect the nature of your dog's coat. In fact, a dry, sparse, or dull coat might be one of the first signs of a health problem in your dog. No matter what kind of coat your dog has-short, long, curly, or wiry-your dog's coat health shows on the surface and can be influenced by environment, diet, and medical issues. To maximize your dog's coat quality, try fish-oil supplements (check with your vet first), and keep him on a high-quality, balanced diet.
