Some rescues use fosters so the animals are kept in a home-like environment. I think its difficult to know what a dog is really like in a shelter unless that's what the dog has come from, a kennel or puppy mill situation, maybe. In the case of the group I foster for, they only pull dogs that are facing the needle. The local shelter contacts rescue groups when a "kill day" comes up (they are running out of room) or if they have a purebred dog they have difficulty placing.
