Forte Pure Paws. The Forte line was developed to provide a solution for damaged coats. Show dogs are subjected 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 starts at the skin level. The Forte line is designed to improve skin quality and facilitate optimal coat growth. Forte works on the existing coat to improve and help repair its current condition.
