Increasing spring temperatures translate into more blossoms, more co-workers calling in sick with hay fever, and more dogs running about the District’s parks and sidewalks. And there are quite a few of them: an analysis of figures obtained through D.C.’s Department of Health, which maintains a registry of the city’s 3,841 pups, reveals that we are a town of terriers (858, including 29 Bostons, 85 Jack Russells, and 21 Soft Coated Wheatens) and retrievers (613, including 5 Chesapeake Bays), with plenty of unusual and rare breeds in the mix (three Norwegian Elkhounds, four Lagotto Romagnolos). Of course, there could be more dogs that aren’t registered.

We’ve located the ZIP codes with the strongest concentration of some of the more recognizable breeeds. Whether you’re trying to see some yippie prissies (chuhuahas: 20001) or avoid them, here’s where the dogs are.
