Pup
From AmtWiki
Pups are the children of members of the Wolfpack who are not yet 14 yrs old, but have been given a waiver to fight. They wear very similar badges but have a white paw print in place of the white wolf's head. They are allowed to become Runners when they reach 14 yrs old and must be elevated to Packmember just like any other petitioner. Pup status is granted at the Packleader's discretion.
