Relevant variables describing the characteristics of dogs' paths and variables extracted from the returning event analysis for each subject (Vizslas; V1 to V5 and the mixed-breed dog; M).

For each variable, averages over the walks and standard deviations between the walks are shown (Mean ± SD), except for time period of the returns and loop length, where the SD of all data is indicated. See more details in Text S1.

针对各变量，均给出各游走的平均值与游走间的标准差（均值±标准差）；但回报时长与回路长度除外，此类变量标注的为全部数据的标准差。详细信息请参见补充材料S1。
