Grayson has a complexity to his behavior that can be a challenge to manage.  If there is a threat of a strange human or unknown activity around the enclosure, Grayson is the first (and sometimes only) pack member to bark howl in an alarm format.  He is not testing for behavior like his littermate, Axel, but is waiting and watching for opportunities.  The biggest conflict that he has is with Denali and is usually associated with food, but his more timid response means he is not as likely to defend food.  Staff work on getting extra meals throughout the week to make sure Grayson gets the resources that he needs.
