For the Pooch With a Sweet Tooth

Sure, dog parks are mostly about physical activity -- but what's exercise without an after-workout treat? Visitors to Alexandria's Del Ray Dog Park, the first fenced-in dog park in Northern Virginia, can take a post-playtime stroll to the Dairy Godmother on Mount Vernon Avenue (about a half-mile away), where dog-friendly frozen yogurt ($1) is served alongside sweets for humans, such as frozen custard and homemade marshmallows.

In the District, canine patrons of Walter Pierce Park in Adams Morgan, where an experimental dog park surrounded by a wire fence was established two years ago, can refresh with Mutt Licks from Doggie Style Bakery, less than a mile away at 18th and Swann streets NW. The homemade dog ice cream comes in flavors such as Canine Chip, Mutt Mint and Snicker Poodle ($2 per cup). Owners may want to swing by Maggie Moo's Ice Cream and Treatery on 18th and Kalorama Road for a lick themselves -- the franchise is known for its unusual flavors (think cake batter and cheesecake) and candy mix-ins.

Making a Splash

If your pup is happiest when paddling, check out Annapolis's Quiet Waters Park, situated on the South River, which has a giant fenced-in area plus a swimming spot just for dogs. In Arlington, Shirlington's dog park fronts the stream Four Mile Run and is a favorite of owners looking for pup playmates of the same breed; on Saturdays, there are often pug, beagle and Labrador meet-ups arranged through Craigslist or Meetup.com.

Members Only

Dogs (and owners) who prefer a clubbier feel may find themselves at home in one of the area's many membership-only parks. Congressional Cemetery in Southeast Washington -- once a scene of homelessness and drug dealing -- is now the priciest dog park around. Owners pay $125 a year, plus $45 per dog, for off-leash access to the 33-acre fenced-in site. For city dwellers, the privately owned cemetery's lush views of distant hills are a pleasant respite from cramped quarters, and pups can romp among the headstones of such historical luminaries as J. Edgar Hoover and John Philip Sousa. Fees go toward restoration of the grounds and buildings.

Non-residents who wish to patronize Gaithersburg's dog exercise area in Green Park must pay $50 a year for each dog to use the 1 1/2 -acre fenced facility, in addition to submitting medical records and a photograph of their pooch. It's free for city residents. In winter, the grassy section is closed to protect the turf, though the gravel area remains open.

The College Park Dog Park, a half-acre fenced-in area with water spigots, is open to residents of Prince George's and Montgomery counties for an annual registration fee of $40 a year for the first dog, plus $30 for other dogs in the same household.
