This chapter describes an original and much-needed approach to understanding worldwide efforts among disadvantaged communities to deal with roaming and unhealthy dogs. Rather than focus on the ways these efforts impact dogs and public health, as is typical of such interventions, we explore how people, too, are socially, psychologically, and economically affected by the dogs. More specifically, we examine the community impact that roaming or unhealthy dog populations can have, including negative or indifferent human-canine interactions; decreased quality of life because of dog nuisances, lack of safety, and disturbing encounters with injured, dead, or suffering dogs; weakened or fractured social ties; and economic losses from reduced tourism, livestock predation, and disease management. Lastly, we review how dog population management can have residual communitywide impact.
