Canine Influenza is a newly emerging infectious disease caused by a “flu” virus. In dogs, a highly contagious strain of the influenza A virus known a H3N8 is able to cause respiratory illness. The virus is relatively new, and dogs have no natural immunity to it. While 100% of dogs are susceptible to influenza infection, about 80% of infected dogs will show signs of infection. Since 2003, there have been numerous reports of influenza outbreaks in veterinary clinics, kennels and shelters.
The most common sign of canine influenza is a persistent cough similar to kennel cough. Some dogs will exhibit a low grade fever, nasal discharge, lack of energy, loss of appetite, and a cough that can last up to several weeks. In about 20% of cases, more severe signs will occur, such as a high fever and pneumonia. Canine influenza is difficult to diagnose and is often confused with kennel cough. |

Fortunately a new canine influenza vaccine was recently approved in the US. The vaccine for Canine Influenza H3N8 is manufactured by Intervet/Schering-Plough and is available through veterinarians. The initial vaccination requires 2 doses, 2-4 weeks apart, followed by annual revaccination. This does not take the place of the Canine Bordetella vaccine for kennel cough. Your dog should continue to be vaccinated for Bordetella.
Dogs housed in community are more at risk for Canine Influenza. We recommend that dogs coming to board at the kennel be vaccinated for Canine Influenza. Many dogs have had very little exposure to other dogs and are very susceptible to the Canine Flu virus and Kennel Cough much like young children going to school. Ask your veterinarian about vaccinating your dog for Canine Influenza.
