研究了53只家犬（Canis,familiaris）在三个任务中的爪子使用情况，以确定动物是否表现出明显的爪子偏好，如果是这样，则探索狗在任务内和任务之间首选爪子使用的方向和强度。研究还探讨了狗的性别对其爪子偏好的影响。研究结果显示，侧化行为与性有很强的关系。雄性和雌性在种群水平上表现出对爪子的偏好，但方向相反。母狗更喜欢用右爪完成所有任务，而公狗更倾向于用左爪。分析显示，在可能的三种任务间相关性中，有两种具有显著的正相关关系。总的来说，研究结果表明，家养狗有两种截然不同的爪子偏好，它们聚集在动物的性别周围。建议在对该物种的偏侧性进行概括之前，进行进一步的工作来探索预训练对狗爪偏好的影响。(C) 2002 Elsevier Science B.V.版权所有
Paw use on three tasks in 53 domestic dogs (Canis,familiaris) was studied to determine whether the animals exhibited a significant paw preference, and, if so, to explore the direction and strength of the dogs' preferred paw use, both within, and between, tasks. The influence of the dogs' sex on their paw preferences was also explored. The findings revealed that lateralised behaviour was strongly sex related. Male and female showed paw preferences at the level of the population but in opposite directions. Female dogs had a greater preference for using their right paw on all tasks, whilst males were more inclined to adopt their left paw. Analysis revealed significant positive relationships for two of a possible three intertask correlations. Overall, the findings suggest that there are two distinct populations of paw preference in the domestic dog that cluster around the animals' sex. It is recommended that further work be conducted to explore the influence of pre-training on dogs' paw preferences before generalisations regarding laterality in this species are drawn.
