Plain-English summary
A dog in China showed signs of respiratory illness, including sneezing and a runny nose, and was found to have a new strain of influenza virus called H5N2. Researchers discovered that this virus could spread between dogs through direct contact. Infected dogs experienced mild symptoms like increased body temperature and coughing, but none became seriously ill. This suggests that dogs can transmit this type of influenza virus to each other, although it doesn't seem to cause severe disease.

Abstract
In 2009, an influenza virus (IV), A/canine/Shandong/JT01/2009 (CA/SD/JT01/09), was isolated from the dog exhibiting respiratory signs in China, and was a novel H5N2. Intraspecies transmission of the virus in dog population had thus far remained unclear. To determine whether the novel H5N2 was transmitted among dogs, we conducted contact exposure and inoculation experiments. Susceptible dogs were housed in the room which the novel H5N2 infected dogs were housed in. As a result, the direct contact resulted in intraspecies transmission. Most of the infected dogs and the sentinel animals developed mild respiratory syndrome, including transient increased body temperatures, conjunctivitis, sneezing, nasal discharge and mild coughing, virus shedding and seroconversion, but no fatal disease. These data suggest that dogs may play a role in transmission and spread of influenza virus.
