Wolves outperform dogs in following human social cues

Abstract
Domestic dogs, Canis familiaris, have been shown capable of finding hidden food by
following pointing gestures made with different parts of the human body.
However, previous studies have reported that hand-reared wolves, C. lupus, fail to locate hidden food in
response to similar points in the absence of extensive training. The failure of
wolves to perform this task has led to the proposal that the ability to
understand others' intentions is a derived character in dogs, not present in
the ancestral population (wolves). Here we show that wolves, given the right
rearing environment and daily interaction with humans, can use momentary distal
human pointing cues to find food without training, whereas dogs tested outdoors
and dogs at an animal shelter do not follow the same human points. In line with
past studies, pet dogs tested indoors were successful in following these
points. We also show that the reported failure of wolves in some past studies
may be due to differences in the testing environment. Our findings indicate
that domestication is not a prerequisite for human-like social cognition in
canids, and show the need for additional research on the role of rearing
conditions and environmental factors in the development of higher-level
cognitive abilities.
