The distribution of paw preferences were studied in 28 dogs. The paw preference was assessed by counting the right and left paw movements performed to remove an adhesive plaster from the eyes. The significance of the right minus left paw reaches in percentages was evaluated statistically in each animal. There were three distinct groups in respect to paw preferences in dogs: right-preferent (57.1%), left-preferent (17.9%), and ambidextrous (25.0%). Statistical analysis showed that the observed frequencies for each group were not merely chance variations which would be expected in a random sample. It was concluded that the population bias can be expressed in a distribution skewed toward a right-hand bias as seen in man.
对28只狗的爪偏好分布进行了研究。通过计算为去除眼部胶布而进行的右爪和左爪动作来评估爪偏好。对每只动物以百分比表示的右爪减去左爪动作次数的显著性进行了统计评估。在狗的爪偏好方面有三个不同的组：右偏好（57.1%）、左偏好（17.9%）和双手灵巧（25.0%）。统计分析表明，每组观察到的频率并非仅仅是随机样本中预期的偶然变化。得出的结论是，群体偏差可以表现为一种向右手偏好倾斜的分布，正如在人类中所看到的那样。
