How to stop your dog from barking at the door!

The video was a good idea, I would say that would be a good method to look into. I'd have to disagree with the poster who used a shock collar though, those are just cruel. Even if it's not a very bad shock, I think it's a mean thing to do to something you love and you're supposed to take care of.

I think the big difference is the philosophy of the training...the video uses positive training, while the shock collar uses negative training. Dogs always respond better to positive training, in my experience.
