Canine Influenza (H3N2) - Health Alert

a highly contagious disease that knows no boundaries

What began as an isolated episode of respiratory disease in 1 state has now become a nationwide health concern for all dogs.  The most recent confirmed case has been reported in Bloomington, IL in April 2016.


The canine influenza virus travels from infected dogs to uninfected dogs through:

· Direct contact

· Coughing, barking and sneezing

· Contaminated clothing, kennel surfaces, food and water bowls, collars and leashes

· People handling or moving between infected and uninfected dogs



· Range from mild to severe: persistent coughing, sneezing, nasal or eye discharge, lethargy, reduced appetite and fever



· Secondary bacterial infection can  develop and may cause more severe  illness and pneumonia.



· Talk to your veterinarian about your dog’s risk of exposure and if the  influenza  vaccine is right for your dog

· Avoid exposing your dog to obviously sick dogs

· If there is a CIV outbreak in your area, avoid taking your dog to areas where dogs gather

· If your dog shows signs of illness, isolate it from other dogs and seek veterinary care

· Wash your hands after handling any dog and especially after handling a sick dog

· Do not share equipment or toys between sick and apparently healthy dogs



· Provide supportive care to keep the dog as comfortable as possible

· Medications may be necessary for severe illness or secondary bacterial infections


RECOVERY: Most dogs recover within 2-3 weeks.


SPECIAL NOTE:  In light of these factors, it is becoming more common to require canine influenza vaccination for all dogs entering pet care facilities, just as is required for Bordetella―another highly contagious pathogen that causes respiratory disease. Vaccine  has been shown to control the spread and reduce the impact of canine influenza symptoms.  DOGS SHOULD BE VACCINATED  2 WEEKS PRIOR TO POSSIBLE EXPOSURE TO RISK AREAS.  There is a initial dose injection and a booster that is given 3 weeks later and every year following.
