I've been trying for almost 2 years to be able to cut my girls nails myself. She either has to be held down by 3 people at the vets and traumatized, or dropped at the groomers and held down by 3 people there. I really want to be able to do this myself with the least amount of stress to her. I think for the 1st 2 years of her life her nails were never cut...

I have tried to desensitize her...by giving cookies while touching her paws. I rub her paws alot which she does not seem to mind, but as soon as I take a firm hold on that paw she starts shaking and bolts...
Forgive me but I have also tried Vita Treat's Pet Calm on her...doesn't work.
Is there something I can ask my vet for to totally calm her down and almost knock her out? I feel so bad but her dew claws are now almost touching her pads and her last nail clipping was in March.
Again forgive me but I am at my wits end. We just tried to clip her dew claws and I thought she was going to have a heart attack.
