This article is from the Hiking/Backpacking With Canines, by Terri Watson with numerous contributions by others.
I'm going to try to compile a list of clubs by area that organize
canine hiking outings. If you know of such, please send me the name,
area and contact info.
Along the same lines, I am not aware of such a club in the Seattle
area, so I am in the process of organizing one. If you're interested
in participating, please send me email. I haven't checked for name
conflicts yet (I'm sure there is one), but if no one is using it, then
I planned to call the group "Cascade Canines".
