Influenza is one of the most contagious diseases and can easily be transmitted to other horses by coughing or direct contact with another horse.  There has been a recent outbreak of confirmed equine influenza in the Red Bluff and Cottonwood area of California that has claimed the lives of 3 horses.  If your horse begins coughing or has a fever, please give us a call immediately. Vaccination is recommend to protect any horses that may be exposed or at risk. If your horse has not been vaccinated recently, a booster may be needed as the protection of the vaccine can decrease over a few months.
