Canine Leptospirosis

Leptospirosis is a bacterial disease that infects and damages the liver and kidneys. It leads to organ failure and usually death.

Rodents and wild animals carry this disease in their urine, which passes into soil or water, where it can survive for weeks.

CAUSES:

Your dog can get leptospirosis through direct contact with the bacteria. Either symptoms will show within a week, or the dog will only become a carrier and not show any symptoms.

Animals can spread leptospirosis to humans, causing flu-like symptoms, and sometimes life-threatening illnesses. If you think you may have been exposed, contact your physician.

SYMPTOMS:

If you notice any of the above symptoms, go to your veterinarian immediately, because leptospirosis can lead to kidney failure and death.

PROGNOSIS:
