Arrrggg I hate nails!!! Haha... I've heard you can wrap them in a towel / stick them into the sleeve of a baggy shirt and then they'll relax a little. (Or maybe it's just cuz they can't move hah.)
Apparently it really helps having someone help you out. When I go to the vet they have a girl holding him and playing with his ears to try to calm him down, and one holding his feet and doing the clipping. Honestly, I just take Buster to the vet to get them done to avoid the headache. I tried clipping him once and he freaked out (I think I got too close to the quick?) and I haven't tried it since. It broke my heart that I hurt him! It costs ms $17 every time which will add up, but until he's REALLY comfortable with me I don't want to risk him hating me.
