The were-dog is just a hereditary lycanthropy thing. They are much weaker than more common lycanthropes for a lot of reasons like they can't partially shift, and they also have no resistance to a vampire's call if a vampire in their area can call dogs, and they also have no control over other animals of their type. Plus some more information on things that make them weaker, but they also have the benefits of not being tied to the moon's cycle and being able to hold off changing, and not having a noticeable aura that would make psychic humans feel uneasy. 

There isn't really any impact of the various groups of werecreatures aside from there being behind the scenes politics that won't come up in this thread. The vampires and werecreatures don't have any wars as far as this RP is concerned. Vampires have no more control over the preternatural world than lycanthropes so there is nothing to subvert from them.
