The Ovens & Kiewa Vet Hospital: Leptospirosis – Update

We Recommend Vaccination against Leptospirosis for Dogs

Due to recent cases of leptospirosis being recorded in dogs in our local area, we are recommending that patients be vaccinated in order to stay protected.

What is Leptospirosis?

Leptospirosis is a bacterial disease of dogs and other mammals that primarily affects the liver or kidneys. The bacteria (Leptospira) that causes leptospirosis is excreted in the urine of affected animals and thrives in standing water. Leptospirosis in cats is very rare and is not associated with clinical disease.

How are Dogs Infected?

Leptospira bacteria are carried mainly by rats and other rodents but can be carried by almost any mammal, including people. Ingestion of infected urine or rodent-contaminated garbage is the most important means of transmission, but some forms of the bacteria can penetrate damaged or thin skin.

What are the Signs of Leptospirosis?

• High fever
• Lethargy
• Loss of appetite
• Hemorrhagic (bleeding), sometimes in the mouth and on the whites of the eyes
• Bloody diarrhea and vomiting may occur
• Presence of a yellow color (jaundice or icterus) in the mouth and whites of the eyes
