Bella absolutely loves it and will come running over as soon as Anyone picks it up. She allows the whole of her back and tail to be brushed and after only a few days will roll over to let us brush her belly, also under her chin, head, ears and bib. I use one of the brushes on the farm dog and gave another to a friend with a long haired cat. They both love being groomed with it.
I am hanging on to the fourth one as a spare. Definitely something we don't want to be without!
