Mylar blanket to retain body heat during cold weather, and deflect heat in hot weather.

Fan and spray bottle of water.

Pets got very hot while evac'ing Rita. Temps were high 90s, maybe even 100s; traffic was very slow or not moving at all, so no wind to cool them, and the truck overheated if running the AC while in park for long periods of time. I sprayed their tummies and used a small towel to apply water to their ears, then fanned them. We sprayed ourselves a lot too. My dog-show friend is the one that suggested the mylar blankets.
