She could also try Rescue Remedy. It didn't work for Penny Lane, but I have heard of other people that have had good results from it. You can get it from health food stores.

What about doggie day care a day or two a week. When Leo used to go to day care - he was one tired pup for a couple of days after. Playing with the other dogs gave him great exercise.

My sister had a GSD who had wind phobia. Anytime there was a windy day the poor baby would just go a little nuts. One time he leaped into the bathtub and ripped out all the plumbing. She eventually had to get some valium from the vet and dope him up with there was a windy day in the forecast.

Good Luck to your friend Jill and Guiness. I hope she finds something that works.
