I had to laugh tonight--I happen to catch an episode of the Dog Whisperer and he was working with two yorkies. He managed to get them to stop barking by doing that "ch, ch ch" thing he does while looking assertive. I have tried that--my dog will continue to bark (if he thinks he hears something or if someone walks by our house--always the same dogs on their walks--you'd think he'd recognize them by now!). Anyhow, I don't know how he does it--I think it works for him because he is a stranger to the dogs because my dog could care less what noises I am making or that I am giving him that touch at the neck like the DW does to get their attention---just doesn't seem to work for me.
