I LIVE IN BERMUDA AND IT IS REALLY HOT AND HUMID HERE MY LABS SWIM IN THE OCEAN BUT I HAVE FANS FOR THEM,I HOSE THEM OFF AND I GIVE THEM ICE CUBES TO CRUNCH
Go to Home Depot (my favorite store) and buy a couple of big circular fans that you can sit on the ground. We put them in our yard underneath shade trees and our gang loves them. They will sit right in front of the fans. Keeps the bugs away and will help keep our dogs dry after they jump into our baby pools and dunk their heads in the water buckets - reduces hot spots.
