i have pets that are heat-sensitive as well as older, i’ll be damned if i won’t make sure they are okay and cool.
We put a floor fan on for our dog. He parks himself in front of it and just sleeps away the hot part of the day. He knows all about a/c and will elect to sleep in the bedroom on very hot nights when we have the portable a/c running and he will sometimes, but not always, follow us upstairs to the rooms we keep cool for the computers. We move the portable a/c into the room my husband uses when he has clients on hot days. We have a/c in our shop building, but if we don’t have to work there on a hot day, we just don’t. Otherwise, we use ceiling fans, floor fans and just stay in the areas with the best ventilation, overhanging eaves and a ceiling fan. Or we spend the day in the pool, if at all possible.
We always have a/c on in the vehicles because the dog is with us. We will take turns staying in the car so we can leave the a/c on for him. He knows where all the vents are and gets close to them until he cools down, then he retreats a bit. You can watch his tongue retreat back into his mouth and his breathing slow down as he reaches a comfortable temperature.
The cat loves the heat and avoids the a/c.
We only use limited a/c when it goes above 85 with high humidity. I love a/c and only ration it due to the cost.
