My dog has weak nerves and has issues with the sit/stay when he can't see me. If I switch him to defensive mentality instead of pack, will this help him? Would the Defense Drive DVD help my situation?

Hi,

I just opened the DVD sales newsletter e-mail on defense drive and it made me continue my thinking on this subject. I have a very weak-nerved dog and if I try to leave him for an out of sight stay he has a look of discomfort/stress and I realize he is not going to get very far in training if he feels this way - therefore, my thinking is he needs to feel different about the exercise... so I have been thinking if I could switch him out of pack drive (which is where I suspect he is since he is worried about my leaving him) and switch him into defense drive then I could have him feel different about it. I have seen a difference in him if I play tug then leave him - so my question is would the defense drive DVD be of help to me in my situation?

Thank you
Ann
