If your pet could speak it would say, "PLEASE Don't Leave Me in Here -- It's Hot!" DOGS and Pets DIE IN CARS! Every year, countless pets die after being locked in cars while their owners work, visit, shop, or run other errands. These tragic deaths are entirely preventable. In fact, when it’s 22°C/72°F outside, the temperature inside a car can soar to over 47°C/117°F within 60 minutes. Please don’t chance it!
