The history of Chavis' Jocko Vernon Jackson bought a puppy from Don Mayfield in 1971 and named him "Hank", the sire to Jocko and 5 other champions. Then Don gave him many more dogs to build his kennel on this bloodline. Champion Jocko was bred by Bob Rast, when he bred his bitch Queenie to Hank.
Jocko, along with Bass' Tramp Red Boy, were the foundation of one of the most successful bloodlines of the past thirty years, the Red Boy/Jocko bloodline.
Jocko was bred to his daughter, Tant's Rose, to produce Tant's Miss Jocko, who was then bred to the pure Red Boy dog, Chavis' Ch. Yellow John ROM, to start the famous bloodline.
Jocko, in addition to being one of the foundation dogs of the Red Boy/ Jocko bloodline, was a first class performance dog. He was matched and won four times between 1977 and 1980. He won over Hanner's Black Jack in 1:08. His second time out he won over Middleton's Bucky, a 2X winner, in a wild 11 minutes of back end techniques. His third was over Hodges' Ch. Brute, a dog reputed to have won 6 or 7 matches. His last time out he won over the black dog of Moutain Man's.
Jocko was matched between 46 and 48 1/2 lbs. and was considered one the better, if not the best, back end dog of his time.
