Causes
The Leishmania parasite, transmitted by the bite of the sandfly, which is active from dusk (May to October). An infected dog does not directly infect other dogs.
Diagnosis
Blood test (serology) and, if needed, cytology of bone marrow or a lymph node. An annual test is recommended in endemic areas.
Treatment
Lifelong treatment to control the parasite burden and the symptoms. A combination of drugs depending on the stage. Regular monitoring of kidney function. There is no complete cure.
Prevention
PREVENTION is key: a repellent collar or spot-on against the sandfly (from May to October), an annual vaccine, and keeping the dog from sleeping outdoors at dusk. Prevention is far more effective than treatment.
