Canine influenza or “dog flu” is a highly contagious disease which is caused by an influenza A-virus. The causative canine influenza virus strains have been classified as H3N8 and H3N2.
H3N2 canine influenza first appeared limited to Korea, China, and Thailand. However in March 2015, an outbreak started in the Chicago area and was determined to be due to an H3N2 strain.
The H3N8 canine influenza virus originated from the H3N8 equine influenza and adapted itself to replicate and infect canine.The H3N2 virus originated from avian influenza which then replicated and infected canines.
In March 2016, the University of Wisconsin School of Veterinary Medicine announced that the H3N2 strain has recently been shown to infect a group of felines in the Midwest area. Their findings suggest the virus is beginning to replicate and infect felines and may potentially spread from feline to feline in the future.
Influenza outbreaks are more commonly seen in high risk situations such as shelters, kennels, doggy day care, grooming & boarding facilities. Unlike human influenza the canine influenza is not seasonal, therefore care for your animals should be considered all year round.
The canine influenza vaccines are intended to control the influenza infection. The vaccine may not prevent infection, but trials have shown that it may reduce the severity and duration of the illness.
The vaccine is given in 2 doses at 3 week intervals. The following years it is given as one booster shot every year.
