- Here, an emerging, threatening disease, influenza in dogs, is presented. Like other mammalian influenza viruses, canine influenza virus (CIV), causes an acute respiratory infection. There is no season for this disease and infections can occur any time of the year. Dogs have acquired two influenza viruses since 1999. Canine influenza H3N8 virus is thought to develop from an equine H3N8 strain, whereas canine H3N2 influenza virus most likely arose through the direct transfer of an avian influenza virus from birds. The H3N8 CIV has only been reported in dogs, whereas the H3N2 CIV has caused clinical cases in dogs and cats in Asia, and antibodies to this virus have been found in both species. Almost all dogs exposed to canine influenza virus become infected, with approximately 80% developing clinical signs of disease. Some dogs have asymptomatic infections, while some have severe illness, however death cases due to CIV infection are rare. Fatal H3N8 cases in racing greyhounds were often characterized by hemorrhages in the lungs, mediastinum and pleural cavity. Severe hemorrhagic, cranio-ventral broncho-interstitial pneumonia was reported in most fatal cases of canine H3N2 influenza in naturally infected dogs from Asia. Experimentally infected dogs also had signs of pneumonia with multifocal to coalescing reddish consolidation, edema and hemorrhages in the lungs. No lesions were found outside the respiratory tract. The majority of infected dogs have the mild form of canine influenza. The approximately 20% of infected animals that do not exhibit clinical signs of disease can still shed the virus. The diagnosis is performed by serological methods, with hemagglutination inhibition (HI) as the test of choice, and by molecular methods as RT-PCR. Treatment is supportive, and often includes antibiotics to control secondary bacterial infections. Vaccines for canine influenza are available in some areas. Infection control measures include isolation of infected animals, cleaning and disinfection of cages, bowls and other fomites, and hygiene measures.
