You won't believe it! I have tried every type of shedding comb you can name. This is by far the most superior product you can possibly use! I was extremely skeptical at first, but having tried everything else, decided to give it a shot. Boy, am I glad I did. I will never use anything else. The first dog I used this on was a heavy shedding German Shepard/Chow mix and it worked wonders. Now, I'm back to order one for a new service dog I'm getting, an Akbash/Great Pyrenees. I'm told he's currently blowing his coat and shedding heavily. This is the only thing I'll use on him. They work wonders.
