I have a little Wahl battery powered trimmer combo kit that's about 1 1/2" wide. I use it to trim his ears, private areas, and feet. It came with another smaller head and blade attachments. It's the best thing ever!! Just try a little at a time. Run it and just let him feel the vibration on the side of it to get him used to it and the sound. I clean up Deuce's ears about once a month. Oh and I always talk softly and calmly when I'm grooming him. It seems to keep him in the mood.
