It's just the influenza virus, when it hits, is more serious. Ten to 20% of those dogs can get bad pneumonia," Steed said.Vets look at where a dog has been. Dog flu is spread in dog shelters and other places with lots of canines."Doggie day care, dog parks, places where lots of dogs are interacting in a small area all the time," Steed said.He said he hasn't diagnosed any dogs with canine influenza so far.There is a vaccine available to protect your pet. Just like humans, the canine influenza vaccine is recommended once a year.If your dog does get the flu, don't be afraid to snuggle him or her back to health."It is species-specific, so this one is definitely not one that you can get from the dog," Steed said.Dog flu was discovered about a decade ago. Steed said it's highly contagious.According to dogflu.com, 46 states have recorded outbreaks so far this year.Watch the video above for the full story.
