In summer, it gets really hot in parked cars, which can be dangerous for pets left inside. Dogs can suffer or even die from heatstroke in just a few minutes. When it's 78 degrees outside, it can get as hot as 100 to 120 degrees in a parked car. On hotter days, like when it's 90 degrees, it can reach up to 160 degrees in less than 10 minutes. Help spread the word by putting this sticker on your car window. It reminds people to leave their dogs at home when it's hot outside. Let's keep our furry friends safe!
