Hi, I have a 10 month old boston terrier with high energy. I have had him since he was 4 months old. I just received the Don Sullivan Perfect Dog DVD and Kit. I have also watched it a couple of times. I have been out with him for the last 3 nights and he is still pulling on the line? Is this normal? I guess I am a little fustrated being that it is very disheartening to keep watching all these examples of dogs that take 5 minutes to correct? Am I doing something?
