Table 1. Ethogram of behaviours recorded during the attention bias test (Monk et al., 2018b).

Behaviour	Definition
Vigilance	Duration with the head at or above shoulder height.
Attention to dog wall	Duration looking towards the closed dog window with binocular vision, determined based on head orientation, for the first 60 s of testing.
Eating	An eating bout began when a sheep took a bite of hay and ended when the sheep became vigilant or moved approximately 30 cm away from the hay. Number of eating bouts (eating frequency) and latency to eat from the time the dog window closed were recorded. Latency to eat was recorded at 180 s if a sheep did not eat during the test.
