Prospect Park, the Central Park of Brooklyn, has off-leash hours from 9pm -9am in the Middle and Upper Long Meadow, Nethermead, and Peninsula areas of the park. Dogs are allowed elsewhere in the park (excepting the playgrounds, zoo, bathing areas, ponds, and sports areas) so long as they are on a 6-foot leash. Several dog drinking fountains have even been installed at the base of existing drinking fountains. Dogs and their owners can be found there every morning, but weekends the numbers are in the hundreds. The first Saturday of each month FIDO, a local dog owners' advocacy group, sponsors the Prospect Park Bark, with treats for both the 2- and 4-legged participants.
