This article was prepared by Pet Sitters, Intl using published material fromMERCK Animal Health. Your vet. may refer to the vaccine as H3N8. If youare not already vaccinating your dog against this virus, be sure to discusswith your vet. Unless your vet. advises against it for particular health issuesrelated to your dog, I recommend that your dog be vaccinated and continueto receive the yearly boosters to protect against this highly contagious illness.____________________________________________Canine influenza virus (CIV) spreads fast whendogs get together
You may have heard: dogs can get the flu, too. It’s a relatively recent development. The virus that causes flu in dogs, canine influenza virus H3N8, was only first identified in January 2004. Dog flu cases have now been reported in 39 states.
One of the factors that makes CIV such a concern for anyone who owns or works with dogs is that the virus can spread quickly and easily.1 Because most dogs have no natural immunity against CIV, virtually all dogs exposed to the virus become infected.2,3 CIV can be spread through direct dog-to-dog contact and through airborne particles released when an infected dog coughs or sneezes.
Recognize the signs of dog flu
Like human flu, canine influenza causes respiratory infection and may lead to more serious conditions like pneumonia. The most common sign of dog flu is a soft, wet cough that may last for up to 3 to 4 weeks. Other signs include fever, nasal discharge, lethargy, and loss of appetite. If you notice any of these signs, have your dog examined by a veterinarian.
However, recognizing the signs of dog flu is not enough to prevent spreading the disease. Here are 3 reasons why:
1. Some infected dogs do not appear to be sick. About 20% of infected dogs show no signs of disease but can still spread CIV to other dogs.3
2. If you’ve spotted signs of flu, it’s probably too late. By the time a CIV-infected dog shows signs of illness, the dog is likely to have stopped spreading the virus. In other words, the damage has already been done. You may have already unintentionally spread the virus to other dogs. And remember, just because you see clinical signs of flu doesn’t mean it is flu.
3. Dog flu cannot be diagnosed by clinical signs alone.4The signs of dog flu are very similar to those of other respiratory infections, such as Bordetella. As a result, dog flu is often mistaken for other conditions.
The first CIV vaccine approved in 2009, Nobivac® Canine Flu H3N8 from Merck Animal Health, has been shown to reduce the spread of disease among dogs.5 This can help reduce the likelihood of dog flu outbreaks. As in human flu vaccination, vaccination in dogs is not 100% effective in preventing flu but can help reduce its impact.
Not only does CIV vaccination offer protection for individual dogs, it also promotes overall immunity for all dogs within a given population. This “community immunity” takes effect when a sufficient number of dogs are vaccinated to limit the spread of the virus.6

Canine influenza virus (CIV)
Wednesday, July 4, 2012
Americans celebrate freedom today and so does SNOW!
This year Snow and I both celebrate every day that we are together. (Read the blog posting I wrote earlier this spring to understand why we couldn't wait until July 4th to celebrate this year).
Just to update you a little, the picture here was taken recently and you can see that her head is tilted. She walks with it tilted all the time now, her appetite continues to be a challenge, she has a stubborn UTI that requires antibiotic injections every few weeks, and mostly likely, she has developed a brain lesion. All of this means that Snow is clearly in the sunset of her life, but she still smiles up at me when I say "Princess, you've seen seven more years of sunrises and sunsets than you would have if "Gotcha Day" hadn't occurred. So we celebrate her independence today and will continue to celebrate every day we have left together!
