The Suburban Pittsburgh Book of the Dog

Allegheny County, Pennsylvania, is one of very few (and apparently the most populous) to publish data on its dog registrations. Nathan Fulton, a student at CMU, offers a summary of Pittsburgh Doggos By the Numbers, though it should be noted that it excludes those within city limits. (With 300k humans in town and a million more out in the burbs, assume we're missing at least a quarter of the doggos)
