The Treeing Walker Coonhound was developed in the Colonial era from crosses ofEnglish Foxhounds. Two breeders from Kentucky, John W. Walker and George Washington Maupin, are given credit for the breed's initial development. The dogs they bred were referred to as Walker Hounds, and were used to hunt raccoons.
In the 1800s, a stolen black and tan dog named Tennessee Lead was crossed into the Walker Hound. Tennessee Lead was of unknown origin, but he greatly influenced the Walker. The Walker Coonhound, Treeing, was first recognized by the United Kennel Club (UKC) in 1905 as a part of the English Coonhound breed, at the request of breeders.
The name was later changed to Treeing Walker Coonhound, and it was fully recognized as a separate breed in 1945. It was recognized by the American Kennel Club (AKC) in January 2012, making it the AKC's 174th recognized breed.
