From what I understand werewolves can't become over encumbered.
Collect everything you need then walk to the exit of the dungeon,transform into your werewolf form and run like the wind.
Of course you would have to stop short of your destination to transform back and walk the rest of the way.
Or better yet just roleplay it and either not carry so much or just deal with it and walk.
You got to toughen up sometime
