Most everyone does early morning walks and late evening walks and exercise. Also take lots of water on trips. Air conditioning, kiddie pools, and ice help out a lot and lots of shade. I try to keep my guys in during the hottest part of the day. If I let them out to run, I will turn on the sprinkler for a little bit if I am not on a water rationing. Thankfully, my guys don't want to be outside for long when it's so hot out. Of course, mine all have short coats, I can't imagine how bad it is for the long, heavy coat pups.
