Dog Flu Arrives In U.S.

This year's human flu season may be about over, but if you have a dog, you need to watch for dog flu. Dr. Kathryn Primm, a veterinarian and the co-author of "Pet Parents Guide to Infectious Diseases," says dog flu appears to have come from Korea.  She says dog flu is like human flu when it comes to symptoms, but unlike human flu, dog flu is year-round.  There is a vaccine, and it's far more effective than human flu vaccine because there are only two dog flu strains.  If you think your dog has canine influenza, call your veterinarian, or you can learn more at dogflu.com.
