You are very brave...I don't think I would be able to do that myself. I know a breeder that use to do her own dewclaw removal until oneday she did it wrong and paralyzed the poor pup. She never did them again.
I get a heart attack every time my pups flinches and pulls away when I cut their nails. I've never made them bleed but it still scares the bejeezus out of me when the pull away like that. hehe
