Season two introduces a new format with head-to-head match ups, pitting a pup against another competitor in their class across working dogs, police K9s and "underdogs," for an epic battle to prove who is best. The winners of each of the three classes face-off head-to-head to determine who is that week's Top Dog. Each week, the winning team will receive a $10,000 cash prize as well as an additional $5,000 to donate to the animal charity of their choice. In the final week of competition, the winning teams return for the ultimate face off for the title of America's Top Dog and an additional $25,000.
