Studies on coordination often present animals with the choice of either cooperating or remaining inactive; however, in nature, animals may also choose to act alone. This can be modeled with the Assurance game, an economic game that has recently been used to explore decision-making in primates. We investigated whether dyads of pet dogs coordinate in the Assurance game. Pairs were presented with two alternatives: they could individually solve an apparatus baited with a low-value reward () or they could coordinate to solve a cooperative apparatus baited with a high-value reward for each dog (). All individuals matched their partner's choices, but after controlling for side bias, only four out of eleven dyads consistently coordinated on the payoff-dominant strategy (). Thus, some dogs are capable of finding coordinated outcomes, as do primates, at least when their partner's actions are visible and coordination results in the biggest payoff for both individuals.
关于协作的研究通常会让动物在合作或保持不活动之间做出选择；然而，在自然界中，动物也可能选择单独行动。这可以用确信博弈来建模，确信博弈是一种经济博弈，最近被用于探索灵长类动物的决策过程。我们研究了宠物狗的二元组在确信博弈中是否会协作。成对的狗面临两种选择：它们可以各自解决一个装有低价值奖励的装置，或者它们可以协作解决一个装有高价值奖励的合作装置。所有个体都与伙伴的选择相匹配，但在控制了偏好侧之后，11个二元组中只有4个始终采用收益占优策略进行协作。因此，一些狗能够像灵长类动物一样找到协作的结果，至少当它们能看到伙伴的行动且协作能为双方带来最大收益时是这样。
