There's really no other way to judge a good dog park than the poop factor. Nothing will ruin your day faster than stepping in a steaming pile of doggy doo, especially if it came from somebody else's mutt. The courteous patrons of West Palm Beach's CityPaws dog park are good enough to regularly clean up their mutts' messes. Unlike many dog parks stuffed into the sans-shade section, CityPaws is well-shaded inside Howard Park, which is full of banyan and oak trees to provide a cool spot for your dog to wrestle in the grass. CityPaws also holds a Smooch Your Pooch contest on Valentine's Day and a doggy costume contest on Halloween. Just make sure to clean up when ballerina Fido makes a mess.
