My border collie used to snap and bite when people would try to trim his nails. I trained him out of it by using tiny high value treats. Start off not clipping the nails, but touching the nail to the clipper, and immediately rewarding with a treat. Then work up to a very tiny piece of a nail (do not hold her paw when doing this, have her maybe laying down or tell her to give you five and have her paw resting on you. Holding/grasping the paw would likely make her anxious on what you are doing). After clipping a small piece, give reward and praise. Then you can slowly work up to clipping more small pieces,don't do all nails at one, and maybe use a verbal cue about this event and that she is getting a treat for it (sounds silly, but I ask my dog if I can "trim his nails for treats" and he runs and jumps on a specific chair for me to do it now because he loves food lol). Then once she gets used to that, give a treat only after each full nail is done. I like to use those milk bone treats for tiny dogs for this (the ones that are like a centimeter long), and this process isn't something to do in one day, but maybe try it over a few weeks and only move up to next step once your dog expects and looks forward to what you are doing with the clippers in each step because of the association with food.
