You wouldn't take a dog out in heat like that. Literally.
Heat like that kills. The young and the old are most at risk.
They were up in the back of beyond. It would probably be an 8 hr flight to the nearest hospital. They may as well have been on the moon.
Except the moon doesn't get that hot. (No atmosphere to hold in the heat. LOL.)
Good point about dogs. The pads on their feet can't take that temperature.
