Pelts

IIRC Kukutux also wears a small hide from time to time! So there is definitely IC evidence of that behaviour.

Depending on how realistic you wanna go with it (and since wolves have no way to use tools / cure leather / make a true 'hide' for wearing) I imagine that the pelts would go rancid over time, and/or leave the wearer smelling pretty funky. It would be a good way to carry an emergency snack or hide your own scent if your character was a rogue, mercenary, or something though.
