Mutant wolves could be found all over the deathlands, alone and in packs.
Ryan was once attacked by a mutant wolf while trying to get into a kenworth truck, after they escape from the ville of Ginnsburg Falls. The wolf stood close to four feet tall at its shoulder. Its fur was matted and had burrs in it, and reeked. Ryan was forced to kill it using his Panga. (Crater Lake)
