Pack animal behavior comprises the behavioural repertoire and load-related responses of domesticated equids—donkeys, mules and horses—used to carry goods on their backs [1]. Because packing demands repeated catching, saddling and loading, the quality of owner-animal interaction, and the handling practices that express it, is recognised as a determinant of their welfare [2]. Loaded animals signal overload through reluctance or refusal to move forward, ears held back, tail swishing, repeated head movement and reduced responsiveness [3]. Standardised field protocols score approach, avoidance and aggression towards an observer alongside health parameters, and the prevalence of these reactions differs between horses, mules and donkeys [1]. In pack donkeys, behaviour is assessed as one of several welfare domains, alongside health, feeding and housing [4].
