An outbreak of canine influenza requiring the treatment of 100 dogs has closed a Chicago animal shelter. Last spring, more than 1,000 dogs in the Chicago area became sick, according to NBC Chicago.

However, there have been no widespread reports of canine influenza in Michigan.

Jennifer Holton at the Michigan Department of Agriculture and Rural Development says Michigan had approximately five canine influenza positive dogs in 2015 and one in 2016 to date.

Canine influenza, or dog flu, was added to the State of Michigan’s reportable disease list in 2015, which means veterinarians and diagnostic labs across the state must notify the Michigan Department of Agriculture and Rural Development if they suspect or have a positive canine influenza test.

The dog flu is a highly contagious respiratory infection in dogs which has not been found to cause human illness.

Holton says most dogs are susceptible to canine influenza; however, most affected dogs recover from illness within two-three weeks. Signs of canine influenza can include fever, lethargy, coughing, and nasal and/or eye discharge.

There is a vaccine available to help provide immunity against H3N8 canine influenza, but there is no vaccine available to protect against the H3N2 strain. Consult with your veterinarian about vaccination options.
