Summary:Cohabiting with humans in the same ecological space requires significant variation in the behavioral repertoire of animals. Behavioral variation can potentially improve the chances of survival of an individual. The influence of humans can be measured by quantifying specific behavioral parameters of the interacting individuals. Sociability or the tendency to be friendly toward others is one of many personality traits in animals that can provide us with insights regarding their relationship with humans. Free-ranging dogs are one of the successful urban-adapted species that interact with humans regularly, which, in turn, influences their behavioral properties. In this study, we tested 600 adult dogs from 60 sites across India, categorized as high, low, and intermediate human flux zones, to understand their degree of sociability toward an unfamiliar human. Initially, a "positive vocalization phase" was carried out. Unresponsive dogs were further tested in a "stimulus phase." The first phase was characterized by positive vocal sounds, while the second one included both food and positive vocalization. In addition, we surveyed a total of 1,200 people from the 60 sites to understand their perception of free-ranging dogs. Dogs in the IF zones were highly sociable compared to the other zones. High human flux zone dogs were reluctant to approach initially but showed an increased approach when food was provided. Low human flux zone dogs were the least sociable, and even the food reward had minimal impact on them. Our study provides the first evidence of behavioral variation in the degree of sociability of free-ranging dogs in urban environments.
