Dog Leishmania Control: Treatment and Prevention in Endemic Areas

Canine leishmaniasis is a serious zoonotic disease requiring long-term management and preventive strategies in endemic regions.

Key Facts

Leishmania infantum is transmitted by sandflies and is endemic across Southern Europe, the Middle East, and Latin America.
Clinical signs include skin lesions, weight loss, renal failure, and ocular changes.
Diagnosis requires serology, PCR, or bone marrow cytology; a staged classification guides treatment.
Allopurinol is the main long-term treatment; meglumine antimoniate or miltefosine are used for induction.
No treatment is curative; lifelong monitoring and maintenance therapy are required.
A licensed vaccine (Letifend) and regular sand fly repellent use reduce infection risk.

Welfare Considerations

Dogs with leishmaniasis face chronic disease, painful skin changes, and progressive organ damage without adequate treatment. In endemic areas, welfare requires both treatment of affected dogs and population-level prevention through vaccination and vector control. Imported cases in non-endemic countries require specialist management and careful owner education about zoonotic risk and lifelong commitment to treatment.

What You Can Do

Use veterinary-recommended sand fly repellents when travelling with dogs in endemic areas.
Discuss leishmaniasis vaccination with your vet if you live in or travel to endemic regions.
Ensure regular 6-monthly blood tests for dogs on long-term allopurinol treatment.
Support organisations working on leishmaniasis control in street dog populations in endemic countries.
