Saw people get in a fight in a parking lot over dogs in an air conditioned car

I was recently sitting in my husband’s car in the grocery store parking lot.

I did not feel like going inside and he only needed a few things, so I decided to sit in the car with air conditioning and music.

I looked over at the car next to me and noticed that there were two dogs, one was sitting in the front seat and one was sitting in the back seat of the car. The windows were closed and my heart immediately dropped because it was a very hot and humid day. I looked a little bit harder and saw that the keys to the car were in the ignition, which means that the owner of the dogs most likely left the air conditioning on for them. I thought to myself that if the owner did not come back in a few minutes, I would call my husband and see if he thinks I should take action or let it go. Before I could do that, I saw two people walking towards the car. One seemed to be the owner and one seemed to be a random person. The two individuals started yelling at each other. The stranger started saying to the owner that they are inhumane for leaving dogs in a hot car. The owner yelled back that the air conditioning was on in the car the whole time. This argument about air conditioning went on and on for a few minutes, and then the owner tapped on my car window and asked if I could defend the fact that his keys were in the ignition the whole time. I told the stranger that I saw the keys in the ignition which means the air conditioning was most likely on.
