Mine has been getting worse and worse with nail trimming. He lets us do anything else - brush teeth, clean ears, mess around with his mouth -- but touch his feet and he flips out. I've been handling his feet since the day we brought him home and been trying to desensitize him of the clippers and nothing is working. I'm about ready to just bring him to the vet and have them hold him down and do it. :\ Hope you have better luck!
