Previous studies of motor laterality in dogs have produced some conflicting results, with inconsistencies in lateral biases across sexes, over time, and across tasks. The current study modified published food-retrieval and tape-removal tests before applying them to 43 dogs. It showed that results derived from 50 observations of a food-retrieval task (Kong test) were consistent with 100 observations. Further, observations during both Kong and the tape-removal tests were consistent both within and between observers. Lateralisation results from both the Kong and Tape tests were generally consistent between breeds and sexes and over time, the only exceptions being the categorical groups during the Tape test and the strength of lateralisation in the Kong test. Of greatest interest in this study was the lack of consistency between results from the two different motor lateralisation tasks conducted. Given that motor lateralisation is said to reflect differences in brain structure or function, differences in task results may indicate differing complexities of the two tasks.

成熟狗的运动侧倾稳定性。

先前对狗的运动偏侧性的研究产生了一些矛盾的结果，性别，时间和任务之间的偏侧性不一致。当前的研究修改了已发布的食物回收和胶带去除测试，然后将其应用于43只狗。结果表明，从一项食物回收任务的50次观察（Kong检验）得出的结果与100次观察一致。此外，Kong和磁带移除测试期间的观察结果在观察者内部和观察者之间都是一致的。Kong和Tape检验的横向化结果在不同性别和性别之间基本一致，但随着时间的流逝，唯一的例外是Tape检验中的分类群和Kong检验的横向化强度。在这项研究中，最大的兴趣是进行的两个不同的运动侧卧化任务的结果之间缺乏一致性。假设运动偏侧反应反映了大脑结构或功能的差异，任务结果的差异可能表明两项任务的复杂性不同。
