No you are not a mean mommy, you just feel guilty that's all. But belive me, you are not alone in having this happen to you. And no, they will never forget. We had that happen when Todd was triming nails on Gandalf. So he's real touchy about his feet. I didn't think we would ever be able to trim again either. The show folks use a dremmel tool. I know that, I've shown dogs and own a dremmel tool. But since Gandalf has never been shown or trained to a dremmel tool for his nails Im thinking ... yeah right.. Im just sure he's going to let me do that to his nails.. guess what? He fell asleep whil we were doing them. So you might try it. It worked for us and now that's all we use on nails......... You are not a mean mommy, ---- happens. I must admit you sound like Michelle who owns Pippin! Worry Wart...lol.... ...Jackie
