The mild form is usually treated with cough suppressants. Antibiotics may be used if there is a secondary bacterial infection. Rest and isolation from other dogs is also important.
The severe form needs to be treated aggressively with a broad spectrum of antibiotics, fluids and other general support treatments. Hospitalization and isolation are necessary until the dog is stable.
A vaccine for the canine flu is currently available, though it should only be considered after speaking with your veterinarian. In addition, there are other respiratory conditions that can be vaccinated against, specifically Bordetella bronchiseptica, the bacteria responsible for what is commonly called "kennel cough."
Any dog that is suspected to have canine influenza should be isolated from other dogs. Those dogs with the mild form of the infection usually recover on their own. Canine influenza is not a contagion issue for humans or other species.
