Dog overpopulation causes enormous welfare harm through stray dog suffering, shelter crowding, and euthanasia, with effective and humane solutions now well established through research.
Dog overpopulation creates welfare suffering at enormous scale — stray dogs face malnutrition, disease, injury, and inhumane killing in many parts of the world. The evidence base for effective population management is now clear: culling does not work because it creates population vacuums rapidly filled by surviving or immigrating dogs, while community-based neutering and vaccination programs sustainably reduce populations while improving dog and human health. The welfare case for evidence-based population management is compelling — reducing the overall population of stray dogs through humane means reduces the total suffering experienced by dogs born into difficult circumstances. Investment in accessible low-cost neutering services is the most direct welfare intervention available.
