合作狩猎是一项对认知具有挑战性的活动，因为个体必须与伴侣协调行动，同时对猎物做出反应。家犬是由狼进化而来的，狼定期进行合作狩猎，但尚不清楚狗是否保持了合作狩猎技能。我们在一个有两个洞口的栅栏后面给两只狗颁发了奖励。由实验者操作的一扇推拉门可以挡住一扇门，但不能同时挡住两扇。这些狗需要协调它们的行动，以便如果其中一只狗要穿过并获取食物，每只狗都在不同的开口前面。所有24对狗都解决了这个问题。在研究1中，我们证明了狗理解这个装置是如何工作的。在研究2中，我们发现，虽然配对的表现并不取决于奖励的可分性，但当两个人都期待奖励时，配对更快地协调他们的行动。然而，这些狗并没有互相监视，这表明它们的解决方案是由每个试图为自己最大化的个体实现的。
Cooperative hunting is a cognitively challenging activity since individuals have to coordinate movements with a partner and at the same time react to the prey. Domestic dogs evolved from wolves, who engage in cooperative hunting regularly, but it is not clear whether dogs have kept their cooperative hunting skills. We presented pairs of dogs with a reward behind a fence with two openings in it. A sliding door operated by the experimenter could block one opening but not both simultaneously. The dogs needed to coordinate their actions, so that each was in front of a different opening, if one of them was to cross through and get food. All 24 dog pairs solved the problem. In study 1, we demonstrated that dogs understood how the apparatus worked. In study 2, we found that, although the performance of the pairs did not depend on the divisibility of the reward, pairs were quicker at coordinating their actions when both anticipated rewards. However, the dogs did not monitor one another, suggesting that their solutions were achieved by each individual attempting to maximize for itself.
