Canine Facial Phenotypes and Expressive Behaviors

This data repository includes individual coding sheets for facial behavior and features (including DogFACS behavioral analyses and original schematic physical phenotype analyses), along with owner-reported survey responses for N=103 companion dogs. Full dataset and dictionary also included for all subjects in final sample.

To assess the complexity of facial physical phenotype and assign a corresponding score, each dog’s face was evaluated using an original matrix (Sexton, 2023) that accounted for both pigmentation and perceptible marks/patterning. Dog facial phenotypes were scored by humans unfamiliar with the individual dogs (i.e. not the human participants).

Objective behavioral measure of facial movements (expressivity) were assessed by independent coders using the Dog Facial Action Coding System (DogFACS) (Waller, et al., 2013). Two certified DogFACS coders manually coded the video samples independently according to the DogFACS manual (Waller et al., 2013).

本数据集仓库收录了面部行为与特征的个体编码表（涵盖犬面部动作编码系统（DogFACS）行为分析及原创图示化体表表型分析），同时附带N=103只伴侣犬的主人报告调查问卷结果。最终纳入研究的所有受试对象均提供完整数据集与数据字典。

为评估面部体表表型的复杂程度并赋予对应分值，本研究采用Sexton（2023）提出的原创评分矩阵，该矩阵同时考量了色素沉着与可见斑纹/图案。犬面部表型由不熟悉受试个体的评分人员完成打分（即非受试人类参与者）。

面部动作（表情表达能力）的客观行为测量指标由独立编码员采用犬面部动作编码系统（DogFACS）（Waller等，2013）完成评估。两名认证的DogFACS编码员依据DogFACS手册（Waller等，2013），独立对视频样本进行手动编码。
