I use the Furminator once or twice a week on my GSD and he coat is gorgeous, it has not been damaged at all by using it. His coat is healthy and shiny, he always looks like he's just had a bath. I love it so much I bought one for my mom to use on her GSD/Husky mix (RIP), it worked magic on her coat. I love this thing!
