I loooooove my dremel tool for nails -- you have to remember that we aren't using the hard-core metal attachements with the dremel!! I use a soft sandpaper attachement and Buster doesn't mind it at all.
We had trouble at first, but just keep up with the treats and the praise, and like Prin said, do one nail at a time, and Odin will come around :-)
Also, when using a dremel, try not to keep it in one spot for long, because it does heat up the nail. I just touch the nail, then stop, touch it again then stop, that way the nail doesn't heat up. Also, if your dremel has different speeds (mine does....but I'm not a tool expert so I don't know if they all do..) Use a low speed, this'll also help not to heat up the nail. Good luck!
