I dremel Heidi's nails. This link helped me a lot when I started using it on her. An almost empty peanut butter jar keeps her busy while I do it. I started by having her wear a muzzle and licking the pb jar while I did her nails, but now leave the muzzle off. I never thought I would get her to be comfortable with the dremel, but now she starts to drool thinking about peanut butter when she sees it.
