[Carol Burke]

What you may want to try is as you start out on your walk and he goes to bite your boots or pants, turn in the opposite direction, give a collar correction and move on, praise him when he is walking nicely, ignore him except to turn away when he is biting your pants. I have a girl who does this and has since puppyhood, she is 4 1/2 now. Her thing is she thinks it's a big joke, once she realizes that today is not the day for her jokes she settles down.
