Strong Pure Paws. The Forte Line was developed to provide a solution to damaged coats. Show dogs are subject to the effects of many products and tools that can damage the fur and deplete the keratin layer. Keratin is the key structural component of your dog's coat. A healthy coat begins at the skin level. The Forte line is designed to improve the quality of the skin and facilitate the growth of a layer in an optimal way. Forte works on existing fur to improve and help repair the condition of the current coat.
