Readers love the Shirlington dog park (2601 S. Arlington Mill Dr.) because it includes a stretch of Four Mile Run. You'll also find dogs all over Roosevelt Island, especially at the small beach on the north side. Manassas Battlefield Park is popular for long walks, with both Young's Branch and Bull Run available for swims.
The South River in Quiet Waters Dog Park (Annapolis; quietwatersdogpark.org) is open to swimming only for dogs. Quiet Waters also has a 1.3-acre fenced park, divided for large and small dogs.
Allowing dogs space to run lets them burn off energy and, well, be dogs. In the past few years, Montgomery County has had three off-leash parks open; Alexandria has new parks as well. You'll find information on Web sites run by Montgomery County Dog Owners (mc-dog.org) and DCDOG (groups.yahoo.com/group/DCDOG).
Congressional Cemetery in Southeast DC was a haven for drug dealers and homeless people until dog owners began frequenting it in the 1990s. Now more than 250 owners pay $125 a year, plus $40 a dog, for off-leash access to the fenced, 33-acre site.
Until this past fall, the cemetery was the only place for dogs to run off-leash legally in DC. Following the successful trial of an off-leash park in Adams Morgan, Walter Pierce Park, the DC Council passed legislation allowing off-leash parks.
Animals--mostly dogs but also cats, rabbits, and guinea pigs--are welcome in many hospitals and nursing homes, where their visits are a pleasant distraction for those who are lonely or in pain.
Pets and owners must be trained first and then can visit patients at places like Inova Fairfax and Mount Vernon hospitals. For more information, visit deltasociety.org and tdi-dog.org or call Leslie Horton, director of Assisted-Animal Therapy at Inova Fairfax, at 703-776-3536.
