Logan Circle teems with social hot spots, gourmet food marts and chic boutiques -- and that's just for your dog. Of course, the up-and-coming neighborhood (bounded by S Street to the north, Massachusetts Avenue to the south, Ninth Street to the east and 16th Street to the west) is much loved by humans, too. But a bevy of pooch-friendly pit stops make it especially well-suited to four-legged friends. Know any bowwows looking to sniff and be sniffed? Here's where to go:

1Logan Circle Park

Logan Circle itself (at the intersection of Vermont Avenue, Rhode Island Avenue, and 13th and P streets) was once known as a destination for loitering and drug activity. That's changing -- slowly. With the support of park police and local businesses, community groups are trying to bring neighbors back inside the circle. Each Wednesday, up to 40 dog lovers on the Circle Dogs mailing list (see next item) gather at 6:30 p.m. in the park. Expect to see a rush of pampered poodles and more modest mutts looking to meet and greet. The group's

hope? That someday soon,

Fido flash mobs will spring up here just as they do at other parks in the city.

2Circle Dogs

Tails are wagging about this two-month-old association of Logan and Dupont Circle dog owners (www.circledogsdc.org), which was formed with a dual mission: to preserve the park just outside Logan Circle proper (on 17th Street between S and T) and to encourage the City Council to authorize a proper dog run in the community. With membership at 150 pups and counting, it's off to a bark-worthy start. In addition to its Wednesday gatherings, it schedules police-escorted dog walks at night.

3Dogs by Day & Nite

Open for pickups and drop-offs around the clock, this dog-sitting service is the last-second planner's dream. While you're away, your pup can play: Sign

him up to get groomed, take power walks or just romp around the

2,300-foot, cageless facility

with up to 60 friends. You can have (almost) as much fun by leafing through the company's Howler newsletter: It comes packed with trivia, quizzes and info about rare breeds. A calendar also offers coupons good for discounts on dog

holidays, such as Scooby Doo's birthday (Sept. 13) and the full moon (Sept. 28).

Open 24 hours. 1724 14th St. NW. 202-986-6301. www.dogsbyday.com.

4Pet Essentials

Dogs by Day's sister operation is a holistic pet-supply store located right next door. You'll find treats, toys and popular natural food brands including Solid Gold, Innova and Wellness. If you don't want to step over owner Linda Welch's two mammoth Saint Bernards to reach the cash register, her staff will gladly deliver your order to you.

Open Sunday, noon-5 p.m.; Monday-Friday, 10 a.m.-8 p.m.; Saturday, 10 a.m.-7 p.m. 1722 14th St. NW. 202-986-7907. www.greenpets.com.

5WagTime

It's not just what's inside this cageless boarding

center and pet-supply

retailer that makes it unique: It also picks up and drops

off your dog at home (and even makes runs to pet-friendly hotels in the area, such as Helix, Rouge and the Carlisle Suites). Grooming and half-day, full-day and overnight boarding are offered. Even if you opt for the doggy delivery service, be sure to make the trek to the store sometime: It stocks an array of all-natural snacks and chew toys, plus designer fashions. Our favorite? An army-green faux-alligator raincoat (so Fendi!) for $50.

Store open daily, 7 a.m.-7 p.m. Boarding open 24/7. 1412 Q St. NW. 202-234-8825. www.wagtimepetspa.com.
