Dog Canine Leishmaniosis Welfare

Leishmaniosis is a parasitic disease of dogs transmitted by sandflies, causing chronic systemic disease with significant welfare implications.

Key Facts

Leishmania infantum is transmitted by phlebotomine sandflies in Mediterranean and tropical regions
Over 2.5 million dogs in Europe are estimated to be infected
Clinical disease causes skin lesions, weight loss, kidney failure, and death if untreated
An effective vaccine has been available in Europe since 2011
Dogs from endemic regions can carry infection without clinical signs for years before disease manifests

Welfare Considerations

Dogs with active leishmaniosis experience chronic systemic illness, painful skin lesions, and progressive organ failure. Early treatment can induce remission but rarely eliminates the parasite entirely.

What You Can Do

Vaccinate dogs in or travelling to endemic regions against leishmaniosis
Use repellent spot-ons and protective collars to prevent sandfly bites
Seek veterinary testing for dogs returning from endemic regions showing weight loss or skin problems
