Exactly what everyone else has said. Like a puppy- use treats, simple commands,a firm voice and lots and lots of praise if they do it right. If you can't do it yourself training school is a good idea- there are experienced trainers that will teach you how to do things with your dog the proper way and your dog will meet some great new dog friends. We took our Golden to dog school when he was younger to get him to socialize and learn some simple commands and there were older dogs there too- and they turned out great. Good luck and keep us posted.
