Be willing to be flexible to accommodate what your dog is comfortable with. There is no way Lila would let me do her nails if she was standing up, but she relaxes when she’s laying down. She sees me coming with the dremel and bag of mini marshmallow and she gets out of bed and lays flat out on the floor. When we started she got a marshmallow after each toe, now it’s after each foot.
Watch out for your own nails, hair, blankets, rugs, etc getting caught up in the dremel.
