Table 1. 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).

Distance from dogs (m)	16.0±3.3	17.0±1.4	18.1±2.6	15.9±3.7	19.9±2.6	19.0±3.6
Time period of the returns (s)	52±47	52±47	40±37	75±74	52±49	108±94
Loop length (m)	16±16	20±14	20±17	12±10	24±21	22±20

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.
