In general, the H3N2 strain has been shown to be contagious longer than the H3N8 strain, two weeks or more after first showing signs of illness. The virus can survive in the environment for up to two days and on hands or clothing for up to 24 hours. Dogs shed pathogens during the incubation period before showing any clinical signs. Infected dogs that never show signs will also shed the virus. Testing within the first few days of illness is very important because this shedding is limited in duration. Testing after an animal has been ill for several days can yield negative results because the virus is no longer present. If your dog is showing signs of any illness, it is best to keep him/her at home and away from other dogs. Taking a dog to a kennel, day care, park, or other area where dogs interact with one another has the potential to spread illnesses.
