In order to grind a Ridgeback’s nails, you need a Dremel – one of those hand-held rotary tools sold at Home Depot and other home-improvements stores. I don’t bother with the battery-powered Dremel – it doesn’t have enough juice. Go with the plug-in and use the cylindrical, sandpaper-covered sanding attachment. Many Ridgebacks respond positively to this method of nail maintenance if properly introduced. This involves gradually introducing the tool, which is loud and vibrates strongly, both factors that can initially unnerve your Ridgeback.
