Fig 1.
Setup of the testing room with the three conditions (0m, 1m, 3m distances), and three positions (A, B, C). The experimenter (E) and the dog entered the room through the side door during the warm up trials, and through the main door (“Enter”) during the test trials. E and dog stood in the waiting area for 15s at the start of each trial.

Finding Owner at Three Distances.
Median value of choices in each condition that were either successful (correct), or identical to the owner’s position during the previous trial (win-stay). Chance level for success (1 correct out of 3) is 33.3%; *** P<0.001, * P<0.05. Chance level for win-stay is 0.899; ## P<0.01.
Fig 3.
Finding Food at Three Distances.
Median value of choices in each condition that were either successful (correct), or identical to the position of the baited food during the previous trial (win-stay). Chance level for success (1 correct out of 3) is 33.3%; *** P<0.001. Chance level for win-stay is 0.899; # P<0.05.
Fig 4.
Average number of correct choices in the two halves of the owner trials. **P = 0.01; ## P<0.01. Dashed line represents chance level (2.5 out of 5).
Fig 5.
Choices by Trial for Owner Average accuracy and use of win-stay strategy across various owner trials.
Dashed line represents chance level for correct choices. Note that in the 2nd trial the target was never positioned to the same place as it was in the 1st. From the 3rd trial onward a win-stay choice (choosing the position the owner was located in the previous trial) could be either correct or incorrect.
