Werewolves transform on the full moon every month. Different than animaguses, they do not remember who they are and who they love when they transform, but become savage beasts. When a werewolf bites a human while in its transformed state the human becomes a werewolf. If, like Fenrir Greyback, a werewolf bites humans while not transformed, the human will not become a werewolf, but may develop a fondness for raw meat. Generally, though, werewolves are normal people apart from their "furry little problems." :)
unless you mean in twilight or something, in which case whenever the hell they want.
Nothing, 'cause humans don't turn onto werewolves
No. Werewolves do not exist. Inter-species transformation is impossible.
No, but there is a mental condition in which someone believes they are an animal.
Well, for one thing they aren't real. And if they were, they would be part human. Werewolves are believed to be humans that turn into blood sucking vampires, furry crooked humans, and maniacs by the full moon. And wolves dont do that.
They don't. Werewolves are fictional.
they eat them
Basically you have your vampires vs. werewolves and humans in between. The Cullen's are vampires, the Black's are werewolves and the Swan's are humans.
vampires can actually turn into werewolves. its the truth (but folklore) Vampires can trans there body to werewolves as werewolves can trans themselfs to vampire. its called camouflage. vampires tend to turn themselves as werewolfs for disguise.
The same that are with dogs and humans.
You can't. Werewolves do not exist, and it is impossible for anyone to become one.
I suppose you could but it probably would be considered cannibalism (werewolves were human once)
Aggressive and violent.
