I actually use this product to groom my schnauzer.
I became frustrated with my regular groomer when my dog came home with an ear infection. There were some bad spots on her and here eyes were all irritated from the soap. She’s usually a cooperative and easy going dog.
I decided to no longer pay all of that money to a groomer and to learn how to groom her myself. So I purchased a Wahl and I combed Youtube for videos and have never looked back. I also use her shaved-off fur in the garden as a deterrent for rabbits.
