Walk your dog when the sun goes down. Let the heat of the day go down and then work with the dog. I usually put mine back in their kennel where they have a bucket of water, but we do not overheat. If they are overheated, I wait, get out of the sun, do the garden hose thing already described, and then put a fan on in the room so the dog can get comfortable first, then in an hour or so I will give water.
I hope the puppy is ok.
When my dogs are hot, they put their feet in their water bucket and paddle it out onto themselve. Silly girls.
