i worked on behalf of the ASPCA last summer where we heard about this happening quite often, and today my husband and i pulled up at target to discover a parking authority officer calling in about a dog locked up in a car in 90+ degree heat. the animal did eventually get taken out of the car, but i can only imagine how miserable he was inside - tongue hanging out all the way, panting excessively, etc.
it only takes a few minutes for the internal temperature of a car to reach over 100 degrees, and animals are not able to cool themselves nearly as easily as humans are. cracking the windows only provides minimal relief. if you MUST leave your dog in the car, do so only for a very short period of time and try to keep an eye on the car (i left my jackson in the car one time to run into arby’s. he watched me through the window and i brought him back water because i was so worried about leaving him for even less than 10 minutes. ofc, he didn’t even drink it because he’s scared to drink out of anything that isn’t his bowl, the big baby).
please, PLEASE do not leave your animals in your car when it is hot outside. if you see an animal suffering in a closed car, contact the police and/or see if you can’t find the owner by telling the car’s make, model and license plate # to nearby stores that you suspect the owner may be shopping in.
