I also cut Jack' while he is asleep, but he wakes up on the first nail.
So. One nail Monday, one nail Tuesday, one nail Wednesday, get the drift. By the time I have the last one done it is almost time for the first one again.
Mainly though he keeps them worn down by walking a mile on asphalt twice a day. He pulls so hard that the road is like a emory board.
Good luck.
