We have a new dog, DH's first doggie ever. He is in canine heaven, getting his first taste of doggy devotion. We haven't left little Honey Girl alone for more than 5 minutes since we rescued her 5 weeks ago. We have neighbors who lost their dog last January and they volunteered to dog-sit for us any time. We just aren't confident that she won't bark yet, so we're starting with leaving her alone for very short periods. For example, we stopped at the library on the way home from work. DH went in to use the bathroom while I took Honey Girl out to pee/poop. I put her back in the car with the windows cracked and went in to get my books. As I walked into the library, DH was walking out, so Honey Girl was left alone for about 30 seconds.
We live in Hawaii. Our heat wave is not as dangerous as the one hitting the Mainland US this week, but leaving a child or pet alone in a car out in the sun can be life threatening. We won't even leave our dog in the car for more than 1 minute; Who are these parents who leave their children alone, unattended, abandoned? Don't they care?
We were never able to have children; I call this type of child neglect the "we can always make more" mindset.
On the other hand, my mother used to let 12 year old me stay in the van when she was taking classes to earn her master's degree. I would read or nap until she got out of class. Sometimes she let me sit quietly in the back of the room. I subliminally learned kinesiology before I could spell it. The 1960s were a different world.
