As if we didn't have enough to worry about with the swine flu, now the dog flu is moving across the country.

As the name suggests, it only affects dogs. But it has many dog owners pretty concerned.

Many people do everything they can to take good care of their dog.

"Especially our dog is like having a child," dog owner Tyler Lamotte said.

So they're concerned about the new dog flu, also known the canine influenza virus, or H3N8, which can be deadly. 

"It's not something we should be worried about, but we should be alert for," veterinarian Dr. Mike Jones said.

The dog flu can not be transmitted to humans, but is very contagious among dogs. 

So at Dogtopia, and other kennels, dogs may soon need canine flu vaccinations to be admitted.

"The dogs play for about 11 hours during the day in an open play environment," Dogtopia owner Tami Land said.

Canine flu was discovered at a dog racing track four years ago and has spread to 30 states.

Symptoms include cough, runny nose, fever and lethargy. 

The vaccine consists of two shots spread two weeks apart and requires a booster shot every year.

Each shot costs about $30, a price some owners are willing to pay in exchange for peace of mind.

"You bet, you bet -- it will be a precautionary measure, worth it too, by all means," dog owner Travis Larson said.
