Give up. Most of these people would toss a baby overboard without regret to save their own animal. They have stated it outright. If another human needed rescue, my pets would have to fend for themselves, as much as I love them.
That's a terrible slander, and not true at all. Why is it so difficult for people with your mindset to grasp that it is entirely possible to save both people and their pets simultaneously. It has been going on all over the disaster area. For every rescuer who says no pets, there's another one who takes both people and pets. There doesn't seem to be any hard and fast rule about it.
I watched two guys being rescued from a roof in New Orleans today by a United States Air Force chopper. They had a small dog with them. The dog went in the basket and onto the help with the 2nd guy.
As I said above, if I were truly faced with no other choice, I'd kill my dogs myself rather than just abandon them. As others have said, the choice is rarely so stark.
