While the dogs haven't gotten used to it yet, the Pecute Dog Nail Griner seems to work well. Not noisy at all (at first, I didn't know if it was on), seems to grind away at the toe nails without discomfort. I think that my dogs aren't used to it ... first, you have to hold them pretty still to get their nail into the hole (could be a little larger ... and I am using this on a terrior and a pug), then the vibration from the grinder. They have had their nails done before professionally, and never seem to enjoy it, but it seems a little better when I have my kids helping me by petting/calming the dogs. Seem solid, so will see how long term use goes.
