We always have to take Ash to the vet and have two people hold her when she gets her nails clipped. I think the reason why she freaks out though is because her nail bed is lower down on the nail than alot of other dogs and she usually ends up bleeding a little because of that fact. Muzzle would be best or you could try and wear the nails down by taking her along the beach if you live close to the beach, that always helped.
