What Is It?

Leptospirosis is a bacterial disease affecting both animals and humans. It can affect the blood, liver, or kidneys


It is transmitted between animals (humans and pets) through contact with infected urine; venereal and placental transfer; bite wounds; or the ingestion of infected tissue. Indirect transmission occurs through contaminated water sources, food or even bedding.


The organism quickly spreads through the bloodstream leading to fever, joint pain, and general malaise, lasting up to a week. The organism settles in the kidneys and begins to reproduce, leading to further inflammation and then kidney failure. Other organ failure (especially liver) can be expected as well. Make no mistake, leptospirosis is a life-threatening disease. Even if the dog survives the acute infection, Leptospirosis may result in chronic kidney or liver damage.

Diagnosis and Treatment...

A diagnosis can be made with a blood test. Treatment consists of antibiotics, fluid replacement, controlling the vomiting, and supportive care designed to address the associated liver and/or kidney dysfunction

Why Is It So Complex?

Within the Leptospirosis family there are many different strains (serovars). Of these different strains there are eight that are of importance for dogs and cats. There are vaccines available, but vaccination against one strain does not protect against the other strains.

Prevention is Best!

We have chosen a Lepto Vaccine, that is proven effective against four strains of Leptospira (grippotyphosa, Pomona, icterohaemorrhagiae and canicola). This is the best product available today. There is no vaccine available that protects against all strains, and some protection is better than no protection.
