The CIV has a two- to four-day incubation period before a dog will show signs, and infected dogs are most contagious during this period. Therefore, an apparently healthy dog may spread CIV. The virus can persist in the environment for 48 hours, and 80 percent of dogs who are exposed to CIV will become infected and show signs. Infected dogs must remain isolated from other pets for four weeks to prevent disease spread.

The incubation period is 1–5 days after exposure. Dogs are most contagious 2–4 days after infection and can be contagious before showing clinical signs. Dogs should be considered contagious up to 4 weeks after exposure. Most exposed dogs (approximately 80%) develop mild infection, with a cough that persists 1–3 weeks that may be similar to the cough of canine infectious tracheobronchitis. Clinical signs may persist for up to 30 days.

It takes about two to four days for clinical signs to develop after contact with the virus. Infected dogs are most contagious during this period before symptoms occur, making rapid transmission likely. This period is referred to as the incubation period. Infected dogs continue to spread the virus for up to 20 days.

Most cases of H3N8 appear two to three days after exposure though the virus has an incubation period of up to five days. For H3N2, dogs may show signs of infection between two to three days afterward. Dogs are most contagious during the incubation period. The virus can remain alive and able to infect dogs for up to 48 hours on surfaces, 24 hours on clothing and 12 hours on someone’s hands.

The incubation period for canine influenza is approximately 2-to-4 days from initial exposure to the dog flu virus. Viral shedding starts to decrease after the fourth day, but dogs with H3N8 remain contagious for up to 10 days after exposure, and dogs with H3N2 remain contagious for up to 26 days. This is made more dangerous by the fact that dogs are most contagious during the incubation period before they start exhibiting symptoms. Almost all dogs that come into contact with the disease will contract it, but not all dogs that become infected show symptoms of the virus. Most vets recommend isolating dogs with H3N2 for at least 21 days to reduce the risk of transmission.
