Swimming pools have gone to the dogs, as well they should. Many breeds adore the water, and a bob in the pool is wonderful therapy for pups suffering from hip dysplasia, arthritis, sports injuries and other painful conditions. Canine Fitness boasts two pools: a deep one for swimmers and a shallow one for little pooches and big splashers. Both offer supervised recreation, exercise and social time for dogs that might otherwise spend too much time chewing the fat on the couch at home. Come on in, Fido, the water's fine.
