So we took in a lost dog and had put up flyers and ads everywhere to see if his family would contact us. It's been three months so we've decided we are going to keep him. He looks pretty young (probably under a year) and he likes to tear things up and jump on people. If it weren't for that he's a very good dog. He lets me know when he needs to go to the bathroom, is great when going for walks, he doesn't jump on furniture etc. It's just the jumping on people and tearing things up that is driving us crazy. I have never trained a dog before so if someone could give me a link, a book suggestion, or even tell me how to train him to not do those things. It would be greatly appreciated. We looked into classes, but the prices are ridiculous. He's a border collie if that matters any.
