The highly contagious equine influenza A virus subtype H3N8 was found to have been the cause of Greyhound race dog fatalities from a respiratory illness at a Florida racetrack in January 2004.
The exposure and transfer apparently occurred at horse racing tracks, where dog racing had also occurred.
CIV possibly caused some of the respiratory disease outbreaks at tracks between 1999 and 2003.

H3N8 was also responsible for a major dog-flu outbreak in New York state in all breeds of dogs.
From January to May 2005, outbreaks occurred at 20 racetracks in 10 states (Arizona, Arkansas, Colorado, Florida, Iowa, Kansas, Massachusetts, Rhode Island, Texas, and West Virginia).
Three areas in the United States may now be considered endemic for CIV due to continuous waves of cases: New York, southern Florida, and northern Colorado/southern Wyoming.

H5N1 (avian influenza) was also shown to cause death in one dog in Thailand, following ingestion of an infected duck

The virus

Influenza A viruses are enveloped, negative sense, single-stranded RNA viruses.
The incubation period is two to five days, and viral shedding may occur for seven to ten days following the onset of symptoms.
It does not induce a persistent carrier state.


About 80% of infected dogs with H3N8 show symptoms, usually mild (the other 20% have subclinical infections), and the fatality rate for Greyhounds in early outbreaks was 5 to 8 percent,[11] although the overall fatality rate in the general pet and shelter population is probably less than 1%.
Symptoms of the mild form include a cough that lasts for ten to 30 days and possibly a greenish nasal discharge.
The fatality rate of dogs that develop pneumonia secondary to canine influenza can reach 50% if not given proper treatment.
Necropsies in dogs that die from the disease have revealed severe hemorrhagic pneumonia and evidence of vasculitis.




Because any vaccine can have negative side effects on some dogs, many dog owners are choosing not to vaccinate because most dogs recover from the flu with mild symptoms, and research indicates that once a dog has recovered from canine influenza, immunity appears to last at least two years.
