I have just read through your other post and you have a very smart and active dog on your hands.

I was just wondering how much exercise your dog gets per day?. Also training classes would help as they are an outlet for any pent up energy and you will be out and meeting lots of people and their dogs.

Your dog is still very young and has alot of learning to do, good luck and keep us posted on any progress.
