I have a friend who swears by a nail file and won't use anything else. I think she got it at the hardware store. I've tried filing with a file they sell for dogs and it doesn't seem to get the job done, although the dogs don't mind it at all.
One caution about using a Dremel or rotary grinding tool. Be very careful you don't get their hair caught in it. They sell a very small battery-powered one for use with fake fingernails. It's really cute and doesn't make as much noise.
