The Michigan Department of Agriculture confirms three cases of the canine flu, and one of them is in Macomb County. The two other cases are in Kent County on the west side of the state.
The virus isn't harmful to humans, but it's possible for people to spread it to other dogs.
As with any disease handwashing can help stop the outbreak.
The canine flu has hit hard this year in Illinois where more than a thousand dogs got sick. Six of them died.
Experts blame the epidemic on a strain called H3N2 that is seen in Asia and leaves pets feeling lousy for about two weeks. The virus gets passed through the air when dogs sneeze or by people when germs jump on hands or clothing, where they can live for hours.
The symptoms can include a lingering cough, lethargic behavior, poor appetite and fever.
You're urged to check with your vet if you think your dog has the flu.
