"....Our experimental reproduction of the disease caused by this isolate induced severe
pathologic changes and showed that infected dogs excreted influenza virus (H3N2) in nasal
discharge but not in feces. This finding suggests that dog-to-dog transmission of subtype H3N2
could occur through the nasal route and that dog-to-dog transmission of the virus could play an
important role in the epizootiology of the disease.

In our study, virologic, serologic, pathologic, and phylogenetic analyses showed crossspecies
infection of an entire avian influenza A virus (H3N2) to another mammalian species,
dogs. Evidence of avian influenza virus infection in pet dogs raises the concern that dogs may be
become a new source of transmission of novel influenza viruses, especially where avian
influenza viruses are circulating or have been detected...."

Interesting. So much for canine influenza being caused by H3N8.

Domestic and feral canine/feline overpopulation is a real problem in many countries. It just might be a factor worth serious consideration in estimating outbreak and transmission risks to humans, in these highly virulent H5 and H3 influenza subtypes that readily cross species barriers.
