Everything You Need
to Know About Dog Flu

Almost All Dogs Are at Risk

Dog Flu is a relatively new disease composed of 2 viral strains: H3N8, first reported in 2003, and H3N2, first reported in 2015. Both strains are extremely contagious and spread easily from dog to dog. The H3N2 strain can even be transmitted to and from cats. Many dogs that visit dog parks and doggie day cares are vaccinated for canine (kennel) cough, more commonly known as Bordetella, a disease that easily can be treated with antibiotics. But for Dog Flu, there is only supportive treatment, and the virus can lead to pneumonia.
