Animal Care Needed

I have a Cane Corso named Xena who is super sweet! But she HATES getting her nails trimmed. She is literally banned from the vet for nail trims because she jumped off the hydraulic table and started bending the harness mount pole! she is very nice and NOT nippy at all but she like to be mouthy and put hands in her mouth. However, I would definitely have her muzzled just because she will be tweaking getting her nails done ( she has never tried to bite, even at the vet! ) and also well because she is a whole cane corso after all! She had her quick cut as a puppy on accident and she has never liked her feet touched sense. If someone could help us out, that would be sick!
