Influenza...Seasonal, H1N1 or K9 Influenza (H3N8) or Just Kennel Cough?

During winter months we are all too aware of the seasonal flu; this year we are particularly aware of H1N1, a variation of Influenza A which can be transmitted from humans to dogs and cats. We have no current therapeutic preventatives for this cross-species transmission other than supportive care. However, are you also aware of Canine Influenza (H3N8), which was originally detected in Florida in 2003? K9 influenza is not transmissible to humans or cats but is a highly contagious viral disease. Since the virus is relatively new, dogs have no natural  immunity to it; virtually every dog exposed to the virus will become infected. The presence of one sick dog can spread the virus and infect many other dogs. You would consider your dog at risk for K9 influenza if: they come from a shelter, rescue center, breeding kennel, or pet store; they board at a kennel or go to doggie daycare; attend group training, visit a groomer, dog parks or engage other dogs on daily walks; enter into dog events or even walk in the local PetSmart. We can now protect against infection with H3N8 vaccine, a killed virus vaccine which had no reported side effects during clinical testing. This vaccination is given initially, then boosted 3 weeks later, and then followed up with annual boosters. If your dog is at risk for Bordetella (kennel cough) then it is at risk for K9 influenza. The symptoms can include a cough (soft and productive or dry) which lasts for more than a few days, a fever (can be low to high grade depending on severity of viral disease), nasal discharge (either clear or colored), lack of energy and loss of appetite.

Currently at HVH, Dr. Zehr and Dr. Blair are offering the vaccination, but are not requiring it yet since there have yet to be any reported cases in W.N.C.

How is canine influenza spread?

Canine influenza spreads the same way that human flu spreads--through direct contact (kissing, licking, nuzzling); through the air (coughing or sneezing); and via contaminated surfaces (such as when a person picks up the virus on their hands or clothing, then touches or pets a dog). Spread can also occur if that same person touches and contaminates another surface-a doorknob, for example.
