I'll start this by saying that I am fairly certain I was not being unreasonable but am interested to know what others would have done in my situation.
Parked up at a supermarket today around midday. Temperature was roughly 26°C. My DD noticed there was a dog in a car a few cars over from us. I looked and there was a little dog (not sure of breed but it was very small but not a pup) locked in a car which was parked in direct sunlight with the windows all cracked maybe an inch max. The dog didn't seem to be in distress but was bouncing around on the back seats. I was only popping in for a few bits for a picnic so made a note to check if car was still there when I returned.
I did my shopping which probably took around 20 minutes. I exited the supermarket and the car and dog were still there. My DH sorted putting the kids and shopping in our car and I wandered over to the car with the dog. Dog seemed in the same state as before. I turned around to go and get my phone out of the car to take a pic of the registration plate so I could alert security within the supermarket when a man pushing a trolley wandered over.
I asked if it was his car and he confirmed it was. I said it was too hot for a dog to be locked in for so long. He raised his voice and semi shouted that he hadn't been long. I replied I knew he had been at least 20 minutes as the car was there when I arrived (I also know no one had gone back to the car as I had noticed him walking around the supermarket quite a few times as he had his I assume grandson in the trolley and his I assume wife was walking very slowly with a cane). He again raised his voice and said he hadn't been long. I wasn't going to argue in front of his grandchild so said his behaviour was disgusting and I returned to my car.
Was I right or was I being a nosy cow? I don't own a dog but I'd have hated to sit in direct sunlight in a locked car for at least 20 minutes. WIBU?
