How do I get my puppy to calm down?

Walk her a lot, twice a day for 30 min each would be a good starting point. They behave better when they get enough exercise. When she starts biting give a stern "No!" and have a toy ready so as soon as she stops you can engage her with something she should be working on. If that doesn't work, give her a short time-out in the kennel, 2 or 3 minutes for her to settle down a little, chill out. When it gets to be too much you can let yourself off the hook, give her a kong filled with a bit of canned food or a little peanut er smeared in it. That will keep her out of trouble for a little bit.
