While we have been spared the high high temps of western U.S., a couple summers ago we had some exceptionally warm weather and Alaskans began to think about buying their first air conditioners ever. At the time we were walking with an elderly dog and I found a cooling jacket on the web. It strapped on like a harness after you drenched it in ice water. We think it worked for her. The owner also ran his air conditioner in the car whenever she was in it, whether with or without people.
