12Domestic dogs (Canis lupus familiaris) are remarkably sensitive and responsive while 13 interacting with humans. Pet dogs are known to have social skills and abilities to display 14 situation-specific responses, but there is lack of information regarding free-ranging dogs 15 which constitute majority of the world's dog population. Free-ranging dogs found in most of 16 the developing countries interact constantly with familiar and unfamiliar humans receiving 17 both positive and negative behavior. Thus, understanding human intentions and subsequent 18 behavioral adjustments are crucial for dogs that share habitats with humans. Here we 19 subjected free-ranging dogs to different human social communicative cues (friendly and 20 threateninglow and high), followed by a food provisioning phase and tested their 21 responsiveness. Dogs exhibited higher proximity seeking behavior as a reaction to friendly 22 gesture whereas, they were prompted to maintain distance depending on the impact of the 23 threatening cues. Interestingly, only the high-impact threatening showed to have a persistent 24 effect which also remained during the subsequent food provisioning phase. An elevated 25 approach in the food provisioning phase elicited the dependency of free-ranging dogs on 26 humans for sustenance. Our findings suggest that free-ranging dogs demonstrate behavioral 27 plasticity on interacting with humans; which provides significant insights into the 28 establishment of the dog-human relationship on streets. 29 30 Dog-human relationship.32 33 Recent trends in research on interspecific interactions have unveiled several important 35 aspects regarding the interplay of the component species. Investigating the eco-ethology of 36 one component species and its trajectories can provide adequate information on the other 37 (Bertness and Callaway , 1994; Thompson, 1999). Human-animal interaction is one such field 38 that attracts researchers to find solutions for evolving problems like human-animal conflict, 39 spread of zoonoses, uncontrolled population growth of unwanted species, etc. In the recent 40 times, studies on human-animal interactions have enabled us to apprehend evolutionary 41 processes like domestication (Hare et al., 2002; MiklĂłsi and Soproni, 2006). Such scientific 45 (Larson et al., 2012; Morey, 2006; Perri, 2016). Thus, exploring the dog-human interaction 46 paradigm, is specifically helpful to analyse the underlying dynamics of the domestication 47 process that enabled the transition of wolf-like ancestors to man's best friend.
48Domesticated dogs interact with humans regularly and possess social abilities to respond to 49 various human actions (Hare and Tomasello, 2005; MiklĂłsi and Soproni, 2006). Dogs are 50 highly sensitive to human communicative cues like pointing, touching, body orientation etc. 51 and in utilising such cues to find hidden rewards such as food (Hare et al., 2002; MiklĂłsi and 52 Soproni, 2006). It has been suggested that domestication played a pivotal role in the 53 development of hu...
