I agree with mostly everyone else here. My cousin has a labrador, who is about 4 or 5 months old now. He is very hyperactive. If we step in the door, he gets very excited and rushes right to us. Though, my cousin hasn't had much trouble getting him to listen to some of her commands. Still, he gets worked up a lot. She's going to bring him to obedience classes soon. There was also I book that I found that may have been of use to her. The book is: The Perfect Puppy : How to Raise a Well-Behaved Dog
by Gwen Bailey. I'm sure you could find it on amazon.com.

Hope all this helps!
