I don't even like leaving mine at home to go to the doctor or the guild. THat is at the most 8 hrs for the doc and less for the guild. My worry is more the wiring in this building than anything else and have asked the neighbors please open the door and let them out of at all possible if this happens. I leave them loose in the house so only the outside door would have to be opened. When we had our fire, I dind't know if the cats made it or not, and was horrified, and then relieved a day later when they showed up. This is a very sad affair. poor dog. Heat stroke is a horrid way to die, you don't just past out, it comes with horrid abdominal pain, as well as panic.. I am sure she could have found someone the dog could stay with, or could have checked on her. Too many things can go wrong, and for a game, why take the chance? I have had people drive over when I was hospitalized, screw everything else, I never want to lose my animals in such a horrid way.
