"Many species can become infected with influenza viruses, but the current 2009 H1N1 virus, which is a mixture of genetic material from different species, has not been identified in animal populations in the United States to date. These viruses are notoriously unpredictable, though, and it is important that we remain vigilant.Pet owners must remain vigilant against canine influenza, which is not the same disease as H1N1 (Swine Flu).
Canine influenza is extremely contagious to dogs, but poses no risk to humans. According to the CDC, symptoms of canine influenza include: cough, runny nose and fever. Some dogs exhibit severe infections that can lead to pneumonia and some dogs show not symptoms at all.
If you suspect that your pooch has been exposed to the disease or if she shows any symptoms or is acting strangely, contact your vet immediately and avoid areas populated by other dogs. While you're talking to your veterinarian, ask about the new flu vaccine.
