When Dog Desk Animal Action reviewed Tanzania for inclusion on the Global Stray Dog Crisis Map, the assessment proved more complicated than expected.
At first glance, Tanzania appears to be a success story. The country has played a central role in some of the world’s most important rabies-control research. International organisations, veterinary researchers and public health experts frequently point to Tanzania as evidence that mass dog vaccination can control rabies effectively without relying on widespread dog culling. Yet alongside that success story is another reality, dogs continue to be culled in parts of Tanzania.
Local authorities have periodically announced dog killing campaigns following rabies outbreaks, and animal welfare organisations have repeatedly intervened to oppose proposed culls. In some cases, thousands of dogs have been targeted during efforts to reduce disease transmission and address public safety concerns. For those following global animal welfare, this creates an obvious question. If Tanzania helped prove that vaccination works, why are dogs still being killed?
The answer lies in understanding the difference between national direction and local response.
For many years, Tanzania has been at the forefront of research into humane rabies control. Scientists working in the country demonstrated that vaccinating around 70 per cent of a dog population can dramatically reduce rabies transmission and eventually eliminate the disease from both dogs and people. These findings became some of the strongest evidence available to support vaccination based rabies control programmes around the world.
The importance of this research cannot be overstated. For decades, governments across the globe relied on dog culling as a primary response to rabies outbreaks. The logic appeared straightforward. Fewer dogs should mean less disease. However, repeated studies showed that the reality was far more complicated. Dog populations often recovered quickly after culling, new animals moved into areas where others had been removed, and disease transmission frequently continued despite large numbers of dogs being killed.
Tanzania helped demonstrate that there was a better way.
Mass vaccination programmes achieved what culling often could not. They reduced rabies transmission while avoiding the welfare concerns associated with large scale killing. The evidence generated in Tanzania has since influenced rabies control strategies far beyond the country’s borders and has become part of the foundation for international efforts to eliminate dog-mediated human rabies deaths.
This is one side of Tanzania’s story. The other side is that public pressure does not disappear simply because scientific evidence exists.
Rabies remains a serious concern in parts of Tanzania. Human deaths still occur. Dog bites generate understandable fear. Communities faced with outbreaks often demand immediate action from authorities. In those circumstances, local governments can come under intense pressure to deliver visible solutions. Removing or killing dogs may create the appearance of rapid intervention, even when longer-term evidence suggests vaccination is more effective.
As a result, Tanzania continues to experience periodic culling campaigns. These incidents do not appear to represent a coordinated national policy aimed at eliminating free roaming dogs. Rather, they reflect local responses to specific outbreaks and public health concerns. Nevertheless, they serve as a reminder that the debate between vaccination and culling has not been fully settled in practice, even where the scientific evidence is strongest.
This tension is precisely what makes Tanzania so interesting from a policy perspective.
Unlike Türkiye, Tanzania is not pursuing a national programme of collecting dogs from the streets and confining them in shelters. Unlike India, it is not experiencing court driven efforts to remove large numbers of dogs from public spaces. Unlike the Philippines, there is little evidence of municipal euthanasia systems operating as a routine component of dog management. Unlike Romania, Tanzania is not characterised by repeated reports of shelter mortality scandals.
Instead, Tanzania occupies a middle ground.
The country has embraced humane rabies control and contributed enormously to global understanding of dog population management. At the same time, local authorities continue to resort to culling under certain circumstances. The result is a nation that demonstrates both the progress that can be achieved through evidence based policy and the challenges of maintaining that progress when public fear and political pressure intensify.
For the purposes of the Dog Desk Animal Action Global Stray Dog Crisis Map, Tanzania remains classified as Stable.
This decision may surprise some readers given the existence of dog culls. However, the map does not classify countries solely on whether dogs are killed. If it did, a large number of nations would immediately move into higher risk categories. Instead, the assessment considers whether culling forms part of a broader systemic problem involving mass removals, shelter overcrowding, widespread euthanasia systems or deteriorating welfare conditions.
At present, the evidence does not support such a classification for Tanzania.
The country’s overall direction remains rooted in vaccination and humane population management. The scientific community, veterinary sector and many public health authorities continue to promote approaches that reduce rabies without relying on mass killing. While localised culls remain a concern and should be monitored closely, they do not currently outweigh the broader evidence that Tanzania is moving in a more humane direction than many countries facing similar challenges.
Perhaps the most important lesson from Tanzania is that evidence alone is not always enough. The country helped prove that vaccination works, yet authorities still face calls to kill dogs when outbreaks occur. This is not simply an animal welfare issue. It is a lesson about policymaking itself. Scientific solutions must compete with public fear, political pressure and demands for immediate action.
Tanzania therefore occupies a unique position on the Global Stray Dog Crisis Map. It is neither a crisis country nor a perfect success story. Instead, it is a reminder that progress is rarely linear and that even where humane solutions have been proven beyond doubt, the temptation to return to older methods never completely disappears.
For now, Tanzania remains in the Stable category. Its future position will depend not on whether rabies remains a challenge, but on whether the country continues to trust the evidence that helped make it one of the world’s most influential examples of humane dog population management.
