Accidentally trained a mafia boss into a dog

Pet trainer Luna accidentally wanders into a mafia execution and unknowingly blows a dog whistle that makes Marco, the city's most dangerous man, sit and shake hands in front of everyone. Forced to become his personal trainer, she soon discovers he's not fully human—he's a military-grade genetically modified hellhound with a human-beast dual form, complete with dog ears and a tail that betray his every emotion. With beef jerky, a custom leash, and the words "good boy," she turns a man who was treated as a weapon for thirteen years into a loyal, tail-wagging boyfriend who answers only to her. And their bond is no accident—her DNA is the only biological key to his neural programming. From mafia boardrooms to underground labs, she conquers every obstacle with dog-training tactics while he rips apart whatever's left. A sweet, ridiculous romantic comedy.
