| contents | Understanding how animals make foraging decisions in challenging or unpleasant contexts sheds light on the processes that underlie cognitive development and the evolution of adaptive foraging techniques in complex ecological settings. In order to investigate how age, gender, and environmental cues impact decision-making and scavenging behaviour, this study explores how juvenile and adult free-ranging dogs (FRDs) respond to aversive stimuli, specifically different concentrations of lemon juice. We conducted a three-bowl choice experiment using lemon juice at concentrations of 25%, 33.3%, and 50% with 73 juvenile FRDs. The juvenile FRD data were compared with adult behavioural data from a prior experiment. The findings indicated that juvenile dogs' foraging behaviour was consistent under provided circumstances, suggesting that their capacity to adapt to aversive acidic stimuli was limited, possibly due to their inexperience and developing cognitive abilities. Adult dogs, on the other hand, exhibited selective foraging by preferring lower acidity and demonstrating more deliberate foraging strategies. Age, sex, and acidity all had significant impact on eating behaviour, with males displaying a higher tolerance to unpleasant stimuli. Markov chain analysis showed repetitive decision-making patterns, especially in adults, indicating continuous sensory evaluation before food consumption, while strategy-making behaviour increased the likelihood of food consumption in juveniles, suggesting juveniles are possibly beginning to build adaptive skills. These findings demonstrate the dynamic interaction of developmental stage, sensory processing, and individual diversity, in developing of foraging strategies of FRDs. This offers new perspectives to understand the cognitive basis of scavenging behaviour in aversive ecological conditions like urban and human-dominated landscapes. |
