Oh no!
I know what you are describing! We have central air but the dogs still love being outside, probably because we have plenty of shade for them to hang out under. Up until this year, though, my parents have never had any type of AC and we would never be able to sleep when ever we stayed over at their house. We would always end up having Buddy sleep in the truck at night (with windows down) because it would be cooler than in their house!
