We are in Australia, and have had very hot summers in the last few years. My 17 year old toy poodle really struggled as we did not have airconditioning back then. She would throw herself directly in front of the electric fan which did not help much. One day she was so distressed, I took her to sit in the vet' waiting room, which was air conditioned. They said, if it happened again, to stand her in a tub of cool water. Fortunately we never had that sort of temperature again, before she passed, and we now have airconditioning
