Yeah, if you do it a couple times a week, just a little, they'll work their way back. I aim to do that, but wind up only doing them about once a week. You can see the quick just before it becomes exposed. However, there have been times when I made ouchies on the little ones and then I feel so rotten. Poor things. Their nails are so soft that it doesn't take long. With the bigger dogs, like Toker, they're very hard and black....takes a long time to get them down. I go straight across and when I've gotten them short as I can, I smooth out and make the edges all around sort of rounded. With Chuli, I have to take an Emory board and hand file a few little sharp spots underneath because her toes are so tiny, it's hard to get the underneath very well without touching her pads, but I can get at them a little bit. At least if you expose the quick a little, it doesn't seem to bleed because I think the Dremel cauterizes it. They don't usually act like there's any pain but there must be. I think the Preparation H might just be the ticket for those times when they become short enough sooner than expected.
