How strong are werewolves?

Werewolves are probably very strong because they can kill vampires by biting them. They are also larger than humans and vampires, which are probably 2 times as small. Even though werewolves can be killed or wounded by a silver substance or a weapon, I have heard that these cunning and big creatures of the night are very strong. I don't know if there are any werewolves but I have heard that if there are werewolves, they are hard to come by.
