Stray Dog Population Management: Evidence-Based Approaches

Stray dog populations cause welfare harm to individual dogs and pose public health risks; evidence increasingly supports humane management over mass culling.

Key Facts

An estimated 200 million stray dogs exist globally, with the highest numbers in Asia and Latin America
Lethal culling does not sustainably reduce stray dog populations as surviving dogs breed to fill the vacuum
CNVR programmes (Catch, Neuter, Vaccinate, Return) stabilise and slowly reduce populations over time
Rabies vaccination of dogs is more cost-effective than human post-exposure treatment
The WHO and OIE both recommend humane population management over culling for stray dog control

Welfare Considerations

Mass culling of stray dogs has been practiced for centuries and consistently fails to deliver lasting population reduction. Removing dogs creates a population vacuum rapidly filled by survivors with increased reproductive rate and by immigration from surrounding areas. Humane alternatives — CNVR programmes that stabilise populations through neutering and vaccination — work with population dynamics rather than against them. They also deliver welfare benefits to individual dogs, who are returned to their territories rather than killed, and create the vaccinated buffer populations that effectively control rabies. The evidence base for humane management has strengthened substantially, and international health and veterinary bodies now endorse it over culling for both welfare and public health grounds.

What You Can Do

Support organisations running CNVR programmes in high-stray-dog regions
Donate to rabies vaccination campaigns for dog populations in endemic countries
Advocate for government adoption of humane stray dog management policies
Avoid purchasing products from destinations with known mass dog culling programmes
Educate others about the evidence showing culling does not sustainably reduce stray dog numbers
