Answering Your Questions About Leptospirosis

Many clients have been asking us about some recent news stories about leptospirosis—a deadly bacteria primarily affecting dogs but also, rarely, in cats.

Leptospirosis is nothing new and in fact, has been in Indiana for many years. The recent increase in diagnosed cases could be due to improved diagnostic tests for the disease, improved tracking, as well as increased contact between pets and the environment where leptospirosis can be found.

Fortunately, there is a leptospirosis vaccine available for dogs, which we recommend for all dogs that have any potential for exposure. If there is wildlife in your neighborhood, your pets are at risk. Another risk factor is exposure to or drinking from rivers, lakes or streams.

This disease can be fatal to our canine friends and is zoonotic, meaning humans can contract it. These are two reasons we highly recommend this vaccine for most dogs.

In some patients, the leptospirosis vaccine can cause a vaccine reaction. In most cases, the reactions we see are mild, with some facial swelling and hives. If your pet has a history of reactions to vaccines, please speak with your veterinarian to discuss the pros and cons of administering this vaccine.
