No, the water should have cooled them off. I've had dogs all my life and currently have an 11 year old black lab mix. He absolutely REFUSES to get in the pool under any circumstances...wierdest lab I've ever seen, probably has something to do with mental anguish due to us strapping a life jacket on him several years ago and taking him "tubing" with us in the lake ...but anway...we have to squirt him down with the hose sometimes when we're outside. Dogs don't have sweat glands, so the evaporation of the water off their skin is what cools them down much like the evaporation of sweat off us humans.
