RachelJ,
You are so right!!! I long for another dog and know I don't have the space or time to handle another one. I think that is why I am so willing to "babysit". My dogs are so easy to get along with that any visitor fits right in. My parents have finally started bringing their Retreiver mix, Scout, every time they visit. She fits right in and lets my dogs know immediately who is the boss! And we had Dexter, a rescue dog that I found and later placed in a loving home, last weekend. He did fine too!! I'd have a ton of dogs of I could afford them!
