Mandibula  is the only female to achieve a World Championship of work title in the  history of the breed. They are not only judged on beauty and structure,  but also nose, personality, temperament, athletic capability,  endurance, self control around non game animals and children, hunting  and much more.

It is a competition on the total function of the Dogo and what they were meant to be. Only 5 dogs alive today have this title, 2 of them live at Circle S Kennels. Cardo and Mandibula. They have proven themselves by the highest standards in the world from catching a multitude of dangerous big game to showing well in competition. There is no other testing available in the world they can complete to prove themselves anymore than what they have already.
