The H3N8 virus and the H3N2 virus are the main subtypes of canine influenza virus (CIV). H3N8 CIV mainly circulates in America, and H3N2 CIV mainly circulates in Asia. However, there was an outbreak of the Asian H3N2 virus in the United States (US) in 2015. Thus, it is important to evaluate the presence of subtype H3N8 virus in dogs in China. From May 2015 to November 2015, 600 sera from pet dogs were collected from Guangzhou, Shanghai, Beijing and Shenzhen for hemagglutination inhibition (HI) assays and microneutralization (MN) assays. Fifty-two (8.66%) of the 600 sera were positive for the subtype H3N2 virus, which matched the previous reports. Five (0.83%) of 600 sera were positive for the subtype H3N8 virus (H3N8 EIV or H3N8 AIV or H3N8 CIV), which is the first report of subtype H3N8 virus infection among dogs in China and remind us to play more attention to this subtype virus. Therefore, further serological and virological surveillance of influenza virus infection among dogs in China is imperative.
H3N8病毒和H3N2病毒是犬流感病毒（CIV）的主要亚型。H3N8 CIV主要在美国传播，而H3N2 CIV主要在亚洲传播。然而，2015年美国爆发了亚洲H3N2病毒疫情。因此，评估中国犬类中H3N8病毒亚型的存在情况很重要。2015年5月至2015年11月，从广州、上海、北京和深圳收集了600份宠物犬血清，用于血凝抑制（HI）试验和微量中和（MN）试验。600份血清中有52份（8.66%）对H3N2病毒亚型呈阳性，这与之前的报告相符。600份血清中有5份（0.83%）对H3N8病毒亚型（H3N8 EIV或H3N8 AIV或H3N8 CIV）呈阳性，这是中国犬类中H3N8病毒亚型感染的首次报告，提醒我们要更加关注这种亚型病毒。因此，对中国犬类流感病毒感染进行进一步的血清学和病毒学监测势在必行。
