It seems to me there are a couple of issues here. I don't think a shelter wants just any JoeBloe walking in one day to say "hey I'd like to help by walking your dogs". The shelter needs to know something about its volunteers though a criminal check might be a bit much. If someone has been volunteering at a shelter for some time so the staff knows them and now new policies are being put into effect, then the shelter should have some sort of informational meeting/handout for all its volunteers so they know what and why. And even when volunteers have been accepted, some mini-training should be included for handling dogs. Many shelter dogs have been abused so I wouldn't want a volunteer who grew up under the "old" system of training with spanking and collar yerking now handling a special needs dog. Actual certification for dog walkers - no - the government intrudes enough.
I enjoyed the video, whilst in Kefalonia snorkelling i saw several Octopi , i think they're fascinating creatures. The ones i saw stayed very still, don't think i'd of been so keen if one had shot towards me.
The shows are the 28th and 29th of March and they are indeed at the David L. Lawrence Convention Center. Thanks for the RV park info. I'll do a search on that.
