I love this tool for my long hair cat. It's quick. He's tolerent, but not for long. It works well on my sheltie as well. She's one of those that like to matt up here & there. I highly recommend this product, But be very careful it's sharp!
I have this on hand for my standard poodle. A great tool for that occasional matt. It is small so doesn't take extra hair with it. I have found it very helpful and less stress on me and my poodle.
