Leptospirosis: An Emerging Problem for Pet Owners

Leptospirosis (“lepto”) has been diagnosed in pets for several decades, but recently, it’s begun to show up across the United States in higher numbers. Although the illness is most often associated with warm, rainy regions, outbreaks have occurred in cities such as Phoenix, New York City, and Denver.

In part, the increased diagnoses can be blamed on climate change and unpredictable weather patterns, more urban-adapted wildlife, and our ability to more accurately diagnose the illness. Because of the severity of lepto among dogs, as well as its risk to people, it’s integral to understand how this disease is contracted and what you can do to protect your pet and others.
