jules I see your point, but there ar eother ways of doing that for a dog. People can visit rescues and take dogs for walks, or help to socialise them by sitting with them and spending time with them in an environment that the dog is at least familiar with, even if it isn't ideal. I just think it must be such a stress, even for "well-adjusted" dogs. The website just makes them sound like objects, and it really gets me.
If people can't dedicate their time to a real dog, they should get a Tamagotchi or buy Nintendogs. I just can't see this as a positive thing no matter how hard I try.
However, the notion of a "trial run", as you imply, jules, would at least help prospective owners to figure out how it is to have a dog in your life full time.
