Leptospirosis Vaccination for Dogs

Leptospirosis Vaccination
Leptospiros Vaccine


What is Leptospirosis?

Leptospirosis is a bacterial infection. It causes fever, vomiting, increased urination, and can lead to kidney and sometimes liver failure and death in both animals and humans.

Leptospirosis has different strains of bacteria that cause infection. These are commonly referred to as different serovars of the bacteria. Of the 8 commonly tested for, the most recent vaccination protects against the 4 most commonly contracted serovars (Leptospira Canicola, Grippotyphosa, Icterohaemorrhagiae, and Pomona).

How can my dog contract Leptospirosis?

It is passed along in the urine of infected animals. Wildlife such as raccoons, deer, and rats are common carriers. Leptospirosis can also be passed to people from wildlife or their own pets. Leptospirosis is found both in country settings and in dense cities.


About the Leptospirosis Vaccine:

The newest and most effective vaccine is Merialís Recombitek 4 Lepto. This vaccine offers excellent protection for a full year (previous vaccines did not). The initial series of Leptospirosis vaccines consist of 2 vaccines given 3 weeks apart. After that it should be boostered annually. The Leptospirosis vaccine should only be given to those dogs that are at risk for contracting it in their specific environment. Not all dogs in all places need this vaccine.

In the past the Leptospirosis vaccine was attributed to causing vaccine reactions (vomiting, diarrhea, facial swelling, hives, and soreness). Though any vaccine can cause a reaction, the new Leptospirosis vaccine typically only causes soreness for 24 hours after injection. If this is bothersome, a single dose of an anti-inflammatory prescribed by your vet can relieve the soreness. Due to the minor increased risk of vaccine reactions, it is recommended the Leptospirosis vaccine be given separately from other vaccinations.

Does my dog need the Leptospirosis Vaccine?

Due to the seriousness of the illness and the fact that we can contract it from our pets, it is important to be aware of the risk level in your area. Ask your vet and your local health department to help assess your risk level. While Leptospirosis is a dangerous disease to both dogs and humans, it is important to note that only dogs at risk need consider vaccination.
