Is your body naturally 103 degrees and covered in hair? Are you unable to open doors to escape, windows to breathe, or call for help? I'm African. I know heat, and I had dogs (and geese and pigs and chickens and monkeys and etc) there. I know heat. The absence keeling over dead does not mean safe. A husky bred for cold weather will not handle heat as well as a small chihuahua with short hair and a small body built for heat dissipation. You are probably not a dog (and if you are: whoosa good dog? It's you! You're the best dog!) and I'm assuming you don't respond to calls of trapped or overheated dogs often like I do. Dogs are living things, and as such, their bodies respond to different situations on an individual basis. Put a happy, hydrated greyhound in a hot car for a while and he'll most likely get out and run laps. His body is made for heat dissipation. Put a hairy golden retriever who has not had water before his trip in a hot car and you have an unresponsive dog in 15 minutes. Your comparisons between animals who cannot help themselves and people who can willingly get up and leave a situation when they are in jeopardy do not undo the many real cases of unintentional, but very real, animal endangerment. Hell, I'm glad when I get a call and it is a "self-righteous asshole" who is wrong about a dog being in danger. Your animal is more important than your attitude or your window.
