To me, these are just common sense things. I take the dogs with me in the summer time too. I have an extra set of keys and leave them locked in with the AC running. It's Texas, so if I left out summer time, that would be most of the year and they would be home all the time. Seriously. Anybody can tell the engine is running. For someone that doesn't actually think of any of that, I may need to leave a sign on the window that says that. To me, it's all just obvious though.
At home, I have a big sized utility fan, I run when we are outside, under the patio umbrella. I also have three kiddy pools, one for the dogs, one for the potted plants to soak in, and a bigger one for me to get in and stretch out. And of course, they go in any kiddy pool they please, lol.
