Disease of the Month

Canine Influenza

Once in a while a completely new virus pops up.  Since it is new, nobody has immunity and just about everyone gets it.  A highly contagious strain of influenza A virus has appeared and is called H3N8 canine influenza.

This is a viral infection distinct and different from others.  It was discovered in 2004 in racing greyhounds in Florida and is now in over 30 states including California.  The dogs at highest risk are those in social environments such as: Boarding Facilities, dog parks, doggy daycares, veterinary hospitals, dog groomers, dog shows, etc.  When most dogs are shedding the virus, they are not displaying clinical signs.    This means the virus is being shed in the environment to the other dogs, while the infected dog appears healthy.  This virus does not affect humans in any way.

Most dogs that are exposed get the infection.  For the majority of the dogs, it causes a soft moist cough, mild fever, and nasal discharge.  However, in about 20% of the cases, dogs can develop pneumonia, severe cough and high fever.  It is estimated that there is an 8% mortality rate in dogs with severe Canine Influenza.

Recently a vaccine for Canine Influenza was given approval by the FDA.  Initial immunization requires two separate subcutaneous injections given at 2 - 4 weeks apart.  Any dog that has contact with other dogs should be vaccinated.

We here at Critter Creek Veterinary Hospital feel very strong about protecting all pets from this disease.  Please feel free to call our office and inquire about this vaccination.
