What a wonderful picture ! You can just see the love and the trust in that dog's eyes as he has his ride through the floodwaters to a safe place on higher ground.
When we had Hurricane Katrina hit New Orleans so hard a few years back, many people did not evacuate when the authorities told them they were supposed to leave right away; so they were still there when the hurricane did come through. It struck the city with terrible force, collapsed the sides of the sea-walls that protected the city; since New Orleans is actually below sea level.
The people who did not evacuate were trapped and the water just kept coming up, once the dikes had broken, so that even the roof of the house was not safe. Plus, there is now good way to get out on the roof from most houses when you are inside without being swept away in the flooding water.
Rescue boats and helicopters came to help these people, but they refused to take pets, and many people stayed in the flooded houses and died as a result of this decision.
I think they have made better plans to help rescue the dogs, too, if something like this should happen again.
