I think that'd be true with some dogs. Other dogs, like the ones I take out sometimes, really need some sort of stimulation like that so they don't go completely insane from depression and loneliness. These are usually the dogs that have been there the longest and sort of expect the fact that they'll be returning to their awful kennel later in the day.

I think the club is a good idea, but what may work better is just going to the shelter and maybe taking the dogs for a walk and playing with them there. That way they won't get the false sense of security. Sometimes it is hard to tell what will be best for each individual dog since it varies so much.
