Treeing Walker Coonhounds are from the United States. They were developed in the 19th century, primarily in Virginia, by crossing English Foxhounds with other coonhounds to create a breed specifically designed for hunting raccoons and other small game. The breed is named after Thomas Walker, who played a significant role in their development and their unique ability to “tree” prey, meaning they chase animals up trees and then alert their hunting partners to the location.
