Dogs get hot and dehydrated just like people do, but they can't tell you about it in words, and their body language doesn't always reflect their discomfort. Remember to keep Rover out of direct sunlight and to adjust the air-conditioning in the part of the car where he's riding. Crate fans
and side-window sunshades
are great hot-weather accessories. If you have no one to dog-sit and absolutely must run into a store or stop for something to eat at a place where pets aren't welcome, park in the shade, crack a window and get back as fast as you can.
