Sure, the idea of Vampires as Hounds has crossed its blog before, and there's likely more to be said on that, but have we considered Vampires as Handlers?

They have the time, tools, and patience (when written right) to not only condition a Hound to their exact wants and needs, but to hand craft a dynasty of Hounds in their image

Within 4 generations, they could have a whole pack that's incapable of considering the idea of life outside their Handler, who all work and live in perfect cohesion
