I bought one of these in a local tack shop about 30 years ago. Having rough and smooth collies of my own and many fosters from collie rescue, it has been my absolute favorite tool. Lately I have been using it on huskies in the county shelter. Nothing is as comfortable to the dog and works as well. I'm thrilled to have found it in your shop. I have been so afraid of losing it over the years and I have never seen it anywhere else.
