I use this for outdoor shampooing of my dogs. I know why? It works so great with my dogs' boar like bristle of hair fur. I have large dogs and their hair on fur are like boar hair. Allot of protein from eating Bison entree. I use it too but my hair is less dense and straight. It helps my dogs with great shine on their hair. Who would of known? And their fur after shampoo cleaned off easily with just hosing them down with clean water. Rinsed. Fabulous dogs and Fabulous owner/people.
