Population Demographics of Owned Dogs in Greater Bangkok and Implications for Free-Roaming Dog Population Management.

Greater Bangkok, Thailand, has large numbers of both owned and free-roaming dogs, two populations that intersect and overlap in complex and nuanced ways. A more robust understanding of owned dog populations is, therefore, important not only in supporting the welfare of owned dogs but also in managing free-roaming dog populations and protecting human health through the prevention of rabies transmission. Over 3200 residents were surveyed to explore the numbers and demographics of owned dogs in Greater Bangkok, plus owners' attitudes and reported behaviours related to their dogs; the acquisition and loss of owned dogs; and caretaking by owners (confinement practices, sterilisation, rabies vaccination, and other veterinary care). The study also considered dog owners' practices in relation to a Catch, Neuter, Vaccinate, Return (CNVR) programme designed to humanely manage dog populations and vaccinate dogs against rabies. Survey results indicate that there are approximately 1.3 million owned dogs in Greater Bangkok. Key findings include high reported rabies vaccination among owned dogs (84% in the past year). Fifty-three percent of owned dogs in the sample were reported to be sterilised, 66% were allowed to roam, and 46% of dogs acquired into households were adopted from the street. The CNVR programme appeared to impact the care and keeping of owned dogs in the community, as it was associated with greater confinement and sterilisation levels.
