A Comparison of Problem-Solving and Spatial Orientation in the Wolf (Canis lupus) and Dog (Canis familiaris)

In this study I tested Benson Ginsburg’s theory that dogs should show diminished ability, compared to wolves, in orienting in three-dimensional space and manipulating objects sequentially. Dogs of all ages and juvenile wolves should do poorly on these measures, but at some time before sexual maturity, the juvenile wolves should begin improving to the level of adult wolves. Two adult and seven juvenile wolves were compared with 40 adult German shepherds. The initial task was to pull a single rope suspended from the ceiling; complexity was increased by the addition of ropes and by changing spatial configurations. Adult wolf performance was consistently successful across all tests and requirements. Juvenile wolves had little difficulty with one and two rope tests, but did more poorly in the three rope tests. The behavior of the dogs grouped into four profiles (# of dogs): non-responders (6), one rope (15), two rope (14), and three rope responders (5).
