In the town of Socorro, New Mexico (one year prior to the formation of the Road Rovers), Professor Shepherd was forced to relinquish experimental transdogmafier technology to General Parvo in exchange for his lost dog, but instead Parvo gives him a bomb that destroys his laboratory. Next year, as normal dogs begin to mutate into monsters, Shephard, who miraculously survived the attack, takes measures to stop Parvo who is behind this. Shepherd selects five different dogs and in his new, secret underground lab, he uses his new transdogmifier on the five, turning them into "Cano-sapiens".
