Canine behaviours that are both desirable and undesirable to owners have a demonstrable genetic component. Some behaviours are breed-specific, such as the livestock guarding by maremmas and flank sucking seen in Dobermanns. While the identification of genes responsible for common canine diseases is rapidly advancing, those genes underlying behaviours remain elusive. The challenges of accurately defining and measuring behavioural phenotypes remain an obstacle, and the use of variable phenotyping methods has prevented meta-analysis of behavioural studies. International standardised testing protocols and terminology in canine behavioural evaluations should facilitate selection against behavioural disorders in the modern dog and optimise breeding success and performance in working dogs. This review examines the common hurdles faced by researchers of behavioural genetics and the current state of knowledge.
对主人来说既合意又不合意的犬类行为具有明显的遗传成分。有些行为是特定品种的，比如马雷马犬的家畜守护行为以及杜宾犬出现的侧腹吸吮行为。虽然在确定导致常见犬类疾病的基因方面进展迅速，但那些与行为相关的基因仍然难以捉摸。准确界定和测量行为表型面临的挑战仍是一个障碍，而且使用不同的表型分析方法妨碍了对行为研究进行荟萃分析。犬类行为评估中的国际标准化测试方案和术语应有助于在现代犬中筛选出行为障碍，并优化工作犬的繁殖成功率和工作表现。这篇综述探讨了行为遗传学研究人员面临的常见障碍以及当前的知识状况。
