UNITED NEWS INTERNATIONAL (UNI) — It’s flu season and not just for humans.

Canine influenza is laying dogs low across North America.

Newsweek said earlier this month cases of the dog flu have been reported in the U.S. states of Washington, California, Arizona, Colorado and Pennsylvania.

The Toronto Sun said that the virus has popped up in Canada for the first time.

Canine influenza is highly contagious among man’s best friend.

The respiratory disease is spread through coughing, barking and sneezing. Dogs in kennels, groomers, daycare facilities and shelters are at a higher risk of getting sick.

Symptoms include decreased appetite, fever, sneezing and runny nose. Officials say infected dogs should be kept isolated for two weeks to avoid passing the virus to others.

Humans can’t come down with dog flu but it can be fatal to a dog. The American Veterinary Medical Association says the virus has a less-than-10-percent mortality rate.
