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. Most 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 as far east as the Piedmont of the Carolinas from an early period.
Architects continue to build dogtrot houses using modern materials but maintaining the original design.
A dogtrot house historically consisted of two log cabins connected by a breezeway or "dogtrot", all under a common roof. Typically one cabin was used for cooking and dining while the other was used as a private living space, such as a bedroom. The primary characteristics of a dogtrot house is that it is typically one or 1 1⁄2-stories, has at least two rooms averaging between 18 to 20 feet (5.5 to 6.1 m) wide that each flank an open-ended central hall. Additional rooms usually take the form of a semidetached ell or shed rooms, flanking the hall to the front or rear.
The breezeway through the center of the house is a unique feature, with rooms of the house opening into the breezeway. The breezeway provided a cooler covered area for sitting. The combination of the breezeway and open windows in the rooms of the house created air currents which pulled cooler outside air into the living quarters efficiently in the pre-air conditioning era.
Secondary characteristics of the dogtrot house includes placement of the chimneys, staircases, and porches. Chimneys were almost always located at each gable end of the house, with each serving one of the two main rooms. If the house was 1 1⁄2 or the rarer two stories, the necessary staircase was usually at least partially enclosed or boxed-in. The stairway was most commonly placed in one or both of the main rooms, although it was sometimes placed in the open hallway. Although some houses had only the open central hall and flanking rooms, most dogtrots had full-width porches to the front and/or rear.
Surviving homes 
The estate known as "Ranch Azalee" in south Webster Parish in north Louisiana, formerly owned by the late State Senator Harold Montgomery, was originally of dogtrot design, having begun ca. 1840 as the James Jackson Bryan House. In 1999, Ranch Azalee was added to the National Register of Historic Places.
Near Nashville, Arkansas, the Noel Owen Neal House was built in 1840. Neal, a farmer, died in 1850. His wife, Hesky, maintained the farm after his death. The house has been moved to Washington, Arkansas, and has undergone restoration, to include the replacing of the roof, porches, and chimneys.
