As a Siberian Husky owner I am going to strongly disagree with you statement that their fur doesn’t shed in the summer - it absolutely does. The rest of the year as well, but the undercoat “blows” and comes out in large handfuls in the summer.
It doesn’t get to 100 degrees here, but she manages just fine (as do her cousins) in the summer (70s or so) by skipping our midday walks, having access to shade and water, and going in the sea whenever possible.
