What the trainer taught me-its like this-the dog has a leash on at ALL times(besides crate, backyard is your call, always in the house). When the dog does anything you don't want her to be doing, you will pop the leash. Its very much like a sharp tug. Not hard, but fast, a very short, abrupt motion. The leash serves two purposes-behavior correction and lets the dog know who's in charge. Be prepared to have something to give your dog to chew on. Make sure she gets as much exercise as possible. Buy some pig ears for her to chew on. Basically at this age, center everything around the leash. It takes some getting used to. I went from having a puppy that I wasn't sure if I can put up with to a dog that will never leave my side in 2 weeks. Just make sure that everybody else that is consistently around the dog is on the same page. This comes from a trainer with 25 years experience.
