Canine influenza is similar to our human flu, except that it has no season, and breakouts can happen seemingly from out of the blue. The respiratory infection is spread very easily from dog to dog. Those who are often in the company of other dogs such as visitors to dog parks, groomers, boarding facilities and competitions are most at risk. The best method of treatment is prevention. The vaccine protects against the more prevalent H3N2 strain of the illness, keeping your pet safe and the pet population as a whole healthier. Ask your veterinarian about more information and whether you pet would be a prime candidate for the canine flu vaccine.
