DOG-FRIENDLY PARKS IN PITTSBURGH, PA

Three rivers converge in this western Pennsylvania city of 305,000, where steep hills create dramatic topography unusual in eastern cities. The metropolitan area's 2.4 million residents experience four-season weather with humid summers in the mid-80s and cold, cloudy winters averaging 28 inches of snow. Pittsburgh's industrial past shaped the landscape, though steel mills have largely closed since the 1980s. The city's neighborhoods occupy hillsides and river valleys, connected by bridges and tunnels. Spring brings late-arriving warmth and blooming foliage, while fall features stunning color across surrounding Appalachian ridges. Gray winter skies dominate November through March.
