Public Health Safety Alert: Two Canine Leptospirosis cases reported in Tucson, AZ.

May 24, 2017

There are now two confirmed positive Leptospirosis (Lepto) cases with potentially 7 dogs affected - all from the same day care facility. The first case was identified 1 week ago with the second case being identified 3 days later. (There have been 70 cases in Maricopa County since February 2016.)

It is likely this outbreak is the result of a non-hospital carrier of Lepto in close proximity to a naive dog population as the vast majority of dogs in our area are not vaccinated for Lepto.

The state veterinarian has been notified of these cases and has recommended vaccinating dogs with the new tetravalent Lepto vaccines as they have a much lower incidence of adverse reaction than the previously reported bivalent vaccines. We carry the tetravalent Lepto vaccines at Rolling Hills Pet Clinic.

This zoonotic disease can put all family members at risk since it can be passed from animals to people. People infected with Lepto may experience flu-like symptoms and may lead to kidney or liver failure or meningitis.

It is spread through infected urine that may be found in various water sources, soil, or on contaminated food or rodents and other wildlife in our area.

Signs of Leptospirosis in Dogs:


    • Decreased appetite or not eating
    • Increased drinking and urination
    • Vomiting
    • Diarrhea
    • Muscle pain, stiffness, reluctance to move
    • Dyspnea (difficulty breathing) or coughing

    • Jaundice
    • Fever
    • Conjunctivitis (red eyes)
    • Weakness and depression
    • Or no symptoms at all


Please schedule an appointment to get your dog vaccinated for Lepto TODAY!
