I don't know. Pack animals like to have the pack around, so maybe the wolf didn't notice. On the other hand, Farley Mowat recorded non-alpha males "babysitting" cubs. On the other other hand, many say Farley Mowat did his wolf observations in the bar....I still don't think it's a good idea to keep a wolf as a pet, though I'm charmed with the story of the "shy dog" who turned out to be a wolf.
