Canine Influenza

By now you have probably heard about the canine influenza virus or H3N8.   This virus is a disease of dogs, not humans.  There is no evidence that this virus infects humans.  The virus is extremely contagious amongst canines.  Most infected dogs will have a mild form of disease, which may be characterized by coughing, sneezing, and nasal discharge.  Ten to twenty percent of infected dogs may progress to a more severe form of the disease, characterized by the onset of pneumonia and may even lead to death.  Some dogs may not develop any symptoms, but will still be able to transmit the disease to other dogs.   Testing is required to confirm the diagnosis.  Cases have been identified in 30 states and the District of Columbia.

Canine influenza virus can be spread through the air via a cough or sneeze and by contact with contaminated objects such as dog bowls and clothing, or by people moving between infected and uninfected dogs.  Dog owners whose dogs are coughing or sneezing should limit unnecessary contact with other animals.

Therapy relies mainly on supportive care while the viral infection runs its course.  Antibiotics are indicated for dogs with secondary bacterial infections.  Most dogs recover from canine influenza within 2 - 3 weeks.  

Because CIV is a new disease, virtually every dog not previously exposed to the virus will become infected.  Many dogs are candidates for the vaccine because of routine contact with other dogs, in such places as dog parks, boarding kennels, dog shows, shelters, adoption centers and pet shops. 

A vaccine is available for H3N8.  There were no reported side effects in the vaccine field safety trial.  Branchville Animal Hospital currently has vaccine in stock.  If you think your dog may be at risk for exposure, please talk to the staff about assessing the risk and vaccinating your pet.
