I'm sorry, this is not even wrong. You want your wolves on the outer perimeter and patrolling the interior. They don't attack structures unless they are trying to get to an enemy, so take down all fences. Interior lines of communication are important irl and in any game ever.

I have not seen my wolves do any damage. Any incidental damage wolves do is trivial to what enemies can do. A pack of wolves can take down a troll fast, but oh no, they destroyed a fence.

Don't mend it. It shouldn't have been there.
