Those are really typical terrier behaviors. They have no boundry's and is why you need to teach them right from wrong. Be persistant and consistant, because it takes awhile to sink in especially when they are so full of energy and forget things in just a few short seconds after being told. The puppy stage can be a lot of work, but when properly trained, they are a jewel. I would have had the puppy in an expen, attached to the front of a wire crate, leaving the door open at all times, and not running in the house. Take it out every hour for lots of running, playing and to potty. The expen is to keep the puppy safe while in training.
