Matt and Petey are the central characters in Puppy Love. They are a representation of an ideal which few (if any) other BDSM romances dare to present. They are a couple who identify as Dom and sub, not merely as a form of sexual roleplay, but as an innate identity. By nature Matt is dominant. He is decisive and self-confident, and he's a born leader. Petey, contrarily, is shy and timid. He is submissive by nature and craves the guidance, affection, and control of a man he regards to be of superior status to himself.
Those who have experienced and understood the theme of this story recognize that the Dom/sub relationship presented is not one in which abuse or bullying is tolerated or glorified. The story is about the evolution of two very unique characters, one Master and one sub. Based upon outward appearances, one would regard the couple as being rather mainstream. They are not clad in leather. They have no piercings or outlandish tattoos. They do not engage in torturous or sadistic sex play which involves beatings or wild sexual fetishes.
