I just watched "Kingdom of the White Wolf" on Disney+ which has exactly that situation. The white wolves of Ellesmere island hunt musk oxen; there isn't much else there except snow hares. At one point after not managing to take down a musk ox for a while they do hunt the snow hares and manage to get one... which serves to cement their pack bonds, but the calories gained were probably less than what the spent on that hunt. Great mini-series, recommended.
