Black Lab jumps into the Tremont Pool during the annual "Doggy Dip" in Upper Arlington, Ohio. With most people abandoning public swimming pools as the weather cools down, those pools are opening themselves up for canine customers. More and more central Ohio public pools are hosting open swims for dogs. The chlorine content is reduced for the canines, and pool staff thoroughly cleans the filters before opening for humans the next summer.
