Mean responses obtained from an Internet based survey from participants (n = 392) when asked to assess traits for natural and modified dogs for each individual breed.

Participants were asked to rate based on a 7 point Likert scale (0 = not at all; 6 = extremely).

要求参与者以7级李克特量表（Likert Scale）进行评分，其中0分表示“完全不”，6分表示“极其”。
