Or you could desensitize him.

Tip: Do this when your dog is sleepy.

1- Start stroking dog. Handle dog's paws. If he doesn't pull back, give him some treats. Handle between dog's paws and toes. Treat for good behavior.
2- Tap the clipper against the nail. Treat for good behavior. If dog flinches, pause and start again. ONLY reward for good behavior (i.e. dog remaining calm). Once dog is comfortable with you tapping each nail with clipper, start to clip a tiny tiny bit off. Treat for good behavior.
3- Eventually, clip more. Treat and praise as usual. If you wish, you can give your dog a stuffed Kong to distract him while you clip his nails.

This sounds easy, but for most dogs, this whole process takes about a few weeks. You may also not be able to do all 4 paws during one session. Also, I use a nail grinder, a Dremel, instead of clippers.
