Humans are not the only ones suffering from this winter's extreme flu season, with veterinarians across the U.S. advising dog owners to get their furry friends vaccinated. 

"Canine flu is one of the infectious respiratory things that we can see in dogs," Dr. Jess Fejes, medical director at the Veterinary Emergency Group, told Fox 29.

Canine flu symptoms include coughing, sneezing, eye and nose discharge, fever, lethargy and trouble breathing. While there are limited treatment options after a dog becomes infected, there is a preventative vaccine. While it is not a core puppy vaccine, dogs that are at risk for catching the flu virus can receive it from their vet.

Vets are now having the flu shot discussion with dog owners. They say not every dog needs the vaccine, but if a dog is social, it’s something an owner should consider.

"It’s going to be somewhat specific, based on region and what they are exposed to, but, generally, dogs exposed to a lot of other dogs, dogs in doggie day care, boarding, things like that," Dr. Fejes explained.

If pet owners choose to keep their dog unvaccinated, there are still ways to ensure that your pooch stays safe this flu season. The viruses spread through the air, so places where dogs congregate, like dog parks, can be risky for man's best friend.

"Canine influenza is transmitted through droplets or aerosols containing respiratory secretions from coughing, barking and sneezing. Dogs in close contact with infected dogs in places such as kennels, groomers, day care facilities and shelters are at increased risk of infection." the American Veterinary Medical Association explained. "Canine influenza can be spread indirectly through objects (e.g., kennels, food and water bowls, collars and leashes) or people that have been in contact with infected dogs."

According to one veterinary office in Florida, an influenza vaccine will only cost between $25 and $35.

Dog owners should always be on the lookout for warning signs. If your dog stops eating or has difficulty breathing, contact your veterinarian. Getting your dog vaccinated for canine influenza may not prevent infection altogether, but it may reduce the severity and duration of the illness, the American Veterinary Medical Association advised.
