A new threat has emerged for tigers in Rajasthan’s Sariska Tiger Reserve. The forest authorities have intensified monitoring of stray and domestic dogs following concerns over the spread of Canine Distemper Virus (CDV), a potentially fatal infection known to affect the ‘big cats’.
Officials said the virus, commonly found in dogs, poses a serious risk to the growing tiger population in Sariska. As a precautionary measure, the forest department has now begun preparations for a large-scale vaccination drive targeting dogs living in and around tiger territories.
Sariska currently has around 52 tigers, with the reserve witnessing a steady rise in the big cat population over recent years. While tigers are regarded as apex predators in the wild, authorities say they are vulnerable to infectious diseases transmitted by animals such as dogs.
According to forest officials, dogs roaming inside tiger habitats and nearby villages will be vaccinated against CDV. Under the proposed plan, puppies will receive the vaccine at six, nine and 12 weeks of age, followed by annual booster doses. Authorities also plan to identify and isolate infected dogs to prevent contact with wildlife.
To strengthen surveillance, the Sariska administration has increased monitoring across the reserve. More than 400 camera traps have reportedly been installed at different locations to track animal movement and identify potential risks within tiger territories.
Chief Conservator of Forests Sangram Singh said the vaccination process would begin soon and the procurement of vaccines is currently underway.
“All dogs moving within tiger territories will be vaccinated. Dogs in villages located inside forest areas will also be covered under the campaign,” Singh said.
He added that special precautions are also being taken around water bodies frequently visited by tigers. Forest teams have been instructed to ensure that dogs remain away from ponds and water sources used by the big cats.
Officials said teams have also been sensitised to immediately report and respond if any symptoms of the virus are detected among dogs or wildlife.
Canine Distemper Virus has earlier caused concern in wildlife reserves across the world because of its ability to spread from domestic animals to wild carnivores. Forest authorities fear that any outbreak among Sariska’s tiger population could prove devastating, making preventive action crucial for conservation efforts.
