Dog Flu (Canine influenza) is an emerging threat to all dogs.
Canine influenza is a relatively new disease commonly referred to as “dog flu.” and can be caused by two different canine influenza viruses. Just like human flu is among humans, canine influenza is highly contagious among dogs. In fact, unless a dog has already had the illness and recovered, almost every dog exposed to the virus will become infected. Two different strains of canine influenza virus have been isolated in the US. Canine influenza virus H3N8 was first reported in 2003, and canine influenza virus H3N2 emerged in March 2015. These strains are not related. Therefore, dogs at risk should be vaccinated against both strains.2 This is because the viruses are relatively new, and dogs have no natural immunity to it. Nobivac® Canine Flu H3N8 was the first vaccine for canine influenza and still is highly effective against this strain. It has been clinically proven to significantly reduce the severity of influenza and the length of time that a dog is sick. Merck Animal Health just recently launched Canine Influenza Vaccine H3N2 under a conditional license. The vaccine has a reasonable expectation of efficacy and safety.33 Your veterinarian can advise you whether canine influenza vaccines should be added to your dog’s vaccination schedule.
