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 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 1½-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 1½ 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 public and notable homes
The town of Dubach in Lincoln Parish, Louisiana, has several surviving dogtrot houses. In 1990, it was nicknamed the "Dogtrot Capital of the World" by the Louisiana State Legislature. The Autrey House Museum, a dogtrot house built in 1849, is located in Dubach; the home is believed to be the oldest extant structure in Lincoln Parish.
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.
The LSU Rural Life Museum in Baton Rouge, Louisiana includes a restored dogtrot house built by Thomas Neal Sr. from the 1860s to the early 1870s in Rapides Parish. The home was lived in by descendants of Mr. Neal until 1976; the house was moved to the museum in 1979.
The Barrington Living History Museum in Washington-on-the-Brazos, Texas, which demonstrates life in mid-19th century Texas, has as its centerpiece the Anson Jones home, a four room dogtrot cabin built by Dr. Anson Jones, the last president of the Republic of Texas. This home was moved to the site in 1936. 
The Log Cabin Village, a living history village owned and operated by the city of Fort Worth, Texas includes the restored Parker Cabin, which was built by a relative of Cynthia Ann Parker in 1848.
The Dallas Heritage Village, in Dallas, Texas hosts a dogtrot house built in the winter of 1845-1846 near what is now the Dallas/Fort Worth International Airport. This dogtrot was originally a log cabin, but was later covered in clapboard.
The Sam Houston Memorial Museum in Huntsville, Texas has two dogtrot cabins.  The Woodland House, the most important structure at the museum, was constructed in 1847 by Sam Houston when he was serving as one of Texas's first United States senators. and has siding over log construction. The Bear Bend Cabin, a four room, story and a half log cabin, was built by Sam Houston as a hunting lodge in the 1850s.
