He had his nail clipped,groomer must have nicked bottom of paw. I was wiping him down including paws. It was frantic type of licking,when I attempted to reach over him on the pallet , at that point he snapped and growled, actually tried to bite me.He is so devoted to my attention. I TOLD HIM IN A FIRM VOICE, DON^t ever do that again. Why, except for apparent pain and wanting to have his way?
