Two different influenza A viruses have infected and spread among dogs since 2000, and both have been widespread in dogs in North America. The H3N8 canine influenza virus arose in the United States as a variant of equine influenza virus. The H3N2 canine influenza virus arose in Asia by transfer of an avian influenza virus to dogs. Both viruses cause mild respiratory disease and are associated with outbreaks in densely housed dogs or those with frequent connections to other dogs. The 2 canine influenza viruses each caused widespread epidemics over at least several years that were associated with localized outbreaks.
自2000年以来，两种不同的甲型流感病毒已在犬类中感染并传播，且在北美犬类中均广泛存在。H3N8犬流感病毒作为马流感病毒的变种在美国出现。H3N2犬流感病毒则是通过禽流感病毒传播至犬类而在亚洲出现。这两种病毒都会引发轻度呼吸道疾病，且与犬只密集饲养环境中或经常与其他犬只接触的犬只群体中的疫情爆发有关。这两种犬流感病毒各自至少在数年时间里引发了广泛流行，并伴有局部疫情爆发。
