TL;DR
This study explores how free-ranging dogs use scent marking for territorial and social communication, revealing gender differences and responses to different scent sources that influence their social interactions.
Contribution
It provides new insights into the complex role of scent marks in territoriality and social dynamics of free-ranging dogs, emphasizing gender-specific behaviors and responses.
Findings
Males are more territorial than females.
Dogs respond strongly to scent marks from different individuals.
Overmarking is predominantly observed in males, especially towards male scents.
Abstract
Scent marks play a crucial role in both territorial and sexual communication in many species. We investigated how free-ranging dogs respond to scent marks from individuals of different identities in terms of sex and group, across varying strategic locations within their territory. Both male and female dogs showed heightened interest in scent marks compared to control, exhibiting stronger territorial responses,. with males being more territorial than females. Overmarking behaviour was predominantly observed in males, particularly in response to male scent marks and those from neighbouring groups. Behavioural cluster analysis revealed distinct responses to different scent marks, with neighbouring group male scents eliciting the most distinct reactions. Our findings highlight the multifaceted role of scent marks in free-ranging dog communication, mediating both territorial defence and…
