WHAT IS LEPTOSPIROSIS?
Leptospirosis is an infectious disease that causes illness in dogs, other animals, and people throughout the US. The disease is caused by a bacteria that lives in water or warm, wet soil. Leptospirosis causes flu-like symptoms, but can develop into a more severe, life threatening illness that can affect the kidneys, liver, brain, lungs, and heart.

HOW DOES MY DOG BECOME INFECTED?
The most common way for a dog to become infected with leptospirosis is by coming in contact with the urine of infected animals, usually in water or on wet ground. Dogs become infected by swimming in or drinking contaminated water, or by playing in areas where infected urine is present.
The bacteria enters the body through the eyes, nose, mouth, or through a break in the skin caused by a cut or scratch. Once a dog has been infected, the bacteria reproduce and multiply, spreading to other parts of the body. If the infection reaches the kidneys and bladder, this dog will spread the bacteria each time it urinates.

WHAT ARE THE SIGNS OF LEPTOSPIROSIS?
Some dogs have no obvious symptoms. Early signs usually appear about a week after infection and may include fever, muscle weakness, and loss of appetite and energy.
