Canine Influenza Virus (Dog Flu)
With the emergence of the highly contagious new Canine Influenza in more regions across the country, please review this information on behalf of your furry friends.
What is the dog flu (Canine Influenza)?
The dog flu is caused by Canine Influenza viruses. There are two main strains of Influenza in dogs, H3N3 and H3N2. Canine Influenza is one of the multitude of bacteria & viruses that contribute to a "Kennel Cough" syndrome.
Is my dog at risk?
Because this virus is new and novel in most regions including the Palouse, it means that no dogs have immunity to it already, leaving all dogs susceptible. Virtually all exposed dogs will develop an infection, and approximately 80% of those will show symptoms. Dogs typically develop symptoms within a few days of being exposed, and dogs that have close social contact with other dogs, or shared indoor air for several hours are at greatest risk. Dogs that attend dog shows, agility trials, dog parks, boarding kennels, grooming salons, or dog daycare facilities should take special precautions, including possible vaccination.
What symptoms should I watch for in my dog?
The most common form of the disease is fairly mild, with symptoms of upper respiratory tract infection including cough, lethargy, reduced appetite, mild fever, sneezing, and/or ocular and nasal discharge. Rarely, some dogs can succumb to a more severe form of the virus, leading to pneumonia. Symptoms of pneumonia include worsening cough, high fever, lethargy, inappetence, and rapid or deep breathing.
How can I protect my dog?
Dogs that attend dog shows, agility trials, dog parks, boarding kennels, grooming salons and dog daycare facilities are at the highest exposure risk of any respiratory illnesses. Those dogs are candidates for vaccination against the new strains of Influenza, as well as the already recommended Bordetella vaccine (another component of "Kennel Cough"). If you have upcoming travel to regions outside eastern WA, consider vaccinating your dog now. Vaccination cannot prevent exposure or symptoms, but it is helpful at reducing the severity and duration of illness. Vaccinated pets are highly unlikely to develop a serious infection, pneumonia, or death from flu. Alpine Animal Hospital carries the bivalent vaccine which confers immunity against both of the known strains.
How does the vaccine work?
The vaccine is made from a killed version of both of the Influenza strains, and stimulates your dog's immune system to better ward off the virus should they be exposed. As reviewed above, Influenza vaccine does not prevent your dog from getting the flu, but does greatly reduce the severity and duration of the illness. The vaccine is given as a series of two, three weeks apart. The second vaccine should be given at least 10-15 days prior to travel or possible exposure. Given the vaccine timeline, owners should start the vaccines at least 5 weeks before travel or possible exposure.
Please schedule an exam to discuss your dog's individual risk, or set up a vaccine appointment today!
