No evidence for a relationship between breed cooperativeness and inequity aversion in dogs.

ABSTRACT: Inequity aversion, the resistance to inequitable outcomes, has been demonstrated in a wide variety of animal species. Inequity aversion was hypothesised to have co-evolved with cooperation but only limited evidence supports this. Dogs provide a suitable model species to test this hypothesis as dogs were previously shown to be inequity averse and dog breeds vary in the extent to which they were selected for cooperativeness. Here, we compared the response of 12 individuals of "cooperative worker" breeds with that of 12 individuals of "independent worker" breeds in the "paw task" previously used to demonstrate inequity aversion in dogs. We also compared the two breed groups' subsequent social behaviours in a food tolerance test and free interaction session. Although subjects in both breed gro
