I use a dremel as well with Shelby. I usuallly can do it while she is laying down and she does not mind at all. She does not like it, but does not give me any trouble either. She just kind of give me the look like "mom.. do you have to do that NOW!". I usually only do two paws at a time. I do the front paws one day and then come back the next day and to the back. When I first got her I tried using clippers but she hated that! She would pull away and mouth at my hand.
