An estimated 200 million stray dogs live worldwide, causing road accidents, disease transmission, and human injuries; humane trap-neuter-return programmes offer a welfare-conscious management alternative.
Stray dogs experience significant welfare problems: malnutrition, parasitism, injury from road traffic and dog fights, and exposure to disease. Mass culling programmes — widely used historically and still practised in some countries — cause enormous suffering, are inhumane, and are ineffective because culled populations are rapidly replenished from remaining fertile dogs. The most effective and humane approach combines trap-neuter-return with vaccination against rabies, stable population management, and parallel programmes to improve responsible ownership among the human population.
