Abstract
A total of 150 nasal swab specimens collected from H3N2 canine influenza -suspected cases in Hanoi from May 2015 to February 2016werediagnosed by the RT-PCR method. The diagnostic results showed that6% of swab samples were positive for H3N2 canine influenza.Dogs infected with canine influenzavirus(CIV)showed typical clinical signs such as coughing, sneezing, difficulty to breath and fever. However, some cases occasionally developedsecondarycomplications, such as severe pneumonia. The rate of infected dogs was highest at 2-6 monthsold. The proportion of infected dogs with H3N2 in winter-spring was higher than in summer-autumn.
