What, Exactly, is the Canine Influenza Virus?

H3N8, get to know it. A friend recently forwarded me an email from a local email hospital about Canine Influenza Virus (CIV), which said that the disease is especially prevalent in the New York City Area. (So far, it has been detected in 30 states.) Clinical signs are similar to those of kennel cough (Bordatella), and they include cough, ocular/nasal discharge, fever, decreased appetite and lethargy.

Oftentimes, CIV is no big deal—much like kennel cough—but sometimes it can progress, and in these cases dogs will exhibit symptoms such as a high fever, spontaneous bleeding, bacterial pneumonia, shock and death. Transmission occurs through contact with an infected dog and its secretions. (Yeah, gross word.)

Since this is a "newly emerging disease," it's important to keep an eye on your pet for symptoms. A CIV vaccine was developed this year, so maybe ask your vet about it if your dog tends to frequent areas like dog parks or kennels. Bear in mind, the vaccine requires a booster 2-4 weeks after the first dose is given.
