They Attacked The Tribe And Killed Most Of Them Off! You Can Read Eclipse Now Why They Hate The Cullens? I'm Guessing It's A Trust Issue Because The Cullens Haven't Done Either Of Those Things! I Guess They Just Don't Like The Idea Of Trusting A Vampire, There Loss I Guess!
theirs enemies cause werewolf-vampire: vampires kill humains and that's what werewolves are trying to prevent and vampires-werewolf: well it's obvious werewolves kill vampires.
why every body have the same answer its's obvious guys .it's cause they're both nighht creatures fighting on the same territory
ware wolfs needs the full moon to phase and vamp's can't walk in sunlight,all off this is twisted now in twilight,facts have been changed,and the rules are changed here of course...that what makes it different and more thrilling than any vampire story every thing here is amplified :there passion,power .they cant be slayed any more by a dagger in the hurt or asilver bullet,sun can't hurt them,they even look more beutifull
oooops sorry for changing the subject all n allthey 're natural born enemies
another theory is because warewolfs were slaves fore vamp's then they fuoght for their freedom like thae story inthe UNDERWORLD
