I am not sure what this is all about but I think it is about training a dog to NOT bark.

My story: I had a former boyfriend who had a sheep dog. The dog ALWAYS barked while riding in the car, to the point of total distraction. I mean one bark right after another. The owner tried everything, including wacking the dog, yelling at it... to make it stop. The owner went away for a holiday and I took his dog for a week. He was a sweet dog except for the darn barking. He was highly trained and was taught to walk next to you without a leash etc. etc. So he was a smart cookie.

I had seen a program on TV (U of PA vet school's program) about positive reinforcement = food for good behavior (and a nice voice) and a strong NO for bad behavior ....... for dogs that were agressive with children. To make a long story short, within one car ride, I had the dog NOT barking. I took a bag of Pepperidge Gold Fish and the dog wanted them more than barking. Eventurally, he got one gold fish per ride. Then none. He stopped barking. The end. Hope that story helps....
