It works great on my Blue Heeler. I've had a furminator for a good bit, and while it does do a good job, I've been getting concerned that I was doing more harm than good to my dogs undercoat, as I read they can be used too often or wrongly unless being used by an experienced animal groomer. This brush without a doubt seems easier on my dogs hair and skin. It doesn't pull hair at all, it glides softly through it and comes out covered in loose hair. It glides so smoothly I didn't think I was doing...
