What are the clinical signs of canine influenza?
Like influenza viruses for other species, CIV causes flu‐like illness consisting of cough, sneezing, and nasal discharge. Virtually all exposed dogs become infected; about 80% develop flu‐like illness, while another 20% do not become ill. Fortunately, most dogs recover within 2 weeks without any further health complications. However, some dogs progress to pneumonia, which is usually due to secondary bacterial infections. While the overall mortality rate for canine influenza is low, the secondary pneumonia can be life‐threatening. There is no evidence for age or breed susceptibility for developing pneumonia during canine influenza.
