I have two German Shepherds about 2 years old. The female (Lisa) accepts the nail cutting and doesn't fight it, but the male (Bart) cries and runs away!! Even simply holding his paw makes him yelp. He'll growl sometimes and grumble something, but he's never done anything more than that so he's not a danger. I'm not sure what else to do with him. I know I can give him medication to put him to sleep, but I want that to be the last resort...
