http://www.mydogiscool.com/ <----I think this is a great website!
I will take my dogs with me for work errands where I am running in, dropping off, and going right back to the car. I bring an extra set of keys and lock the doors and leave the car on and the AC running. Emergency brake on. And I always hope they don't unlock the doors!
I believe there was a tragic situation where the AC was left on but the car died and the dogs were trapped. I would not use my system for things that took longer than 5-10 minutes, and I use my cell phone clock to time it.
