RE: Please remember people it is summer and our pets can overheat!
This is such a huge problem across the globe; not in just in the USA. I hear about pets getting too much heat while being left in a car and with barely a cracked window. It should be left down about 1-2 inches and not on just one window. All windows should be down that much. This will allow for air flow across the whole vehicle and should be parked in the shade. If you have a pet that is caged or boxed, place them in the back seat floor and put a towel over it. The animal will think it's nighttime and go to sleep, which will allow their bodies to cool off.
