The dogtrot, also known as a breezeway house, dog-run, or possum-trot, is a style of house that was common throughout the Southeastern United States during the 19th and early 20th centuries. Some theories place its origins in the southern Appalachian Mountains. Some scholars believe the style developed in the post-Revolution frontiers of Kentucky and Tennessee. Others note its presence in the South Carolina Lowcountry from an early period. The main style point was a large breezeway through the center of the house to cool occupants in the hot southern climate.
