Hi Brittany,

Great question and an important one at the moment...

Canine influenza (aka dog flu) is an extremely contagious respiratory infection that is caused by an influenza A virus.

In the US 2 strains have been documented so far.

The first one, started in 2004, and was an H3N8 influenza A virus (closely related to the virus that causes Equine Influenza).

The second, starting more recently in 2015 in Chicago, was caused by a different canine influenza virus, H3N2. This one had only previously been reported in Korea, China and Thailand. H3N2 is thought to have resulted from the direct transfer of an avian influenza virus to dogs.

2 forms of canine influenza are seen -

Mild - soft, moist cough for 10 to 30 days.

Severe - high fever (104ºF to 106ºF) and pneumonia like clinical signs
