On Saturday, my dear friend Jody's healthy, beautiful, young Labrador died from canine influenza. Last weekend he was running agility and the picture of health. He started coughing on Thursday and was gone by Saturday morning. We are all in shock. Her other dogs are also sick but doing better (although the most elderly dog is hospitalized because he is tiny and old and its hit him fairly hard).

 

I had no idea that there was an influenza that could take out a healthy young dog in 3 days. Not all dogs who get it will have such an effect, but its a possibility. Its apparently a mutation of a horse flu. The CDC has some info on it, and there is a vaccine. I know I will be talking to my vet this week as my dogs go to places where they could come in contact with other dogs.

 

I wanted to share this info here in case anyone else wanted to talk to their vet about it.

 

What is canine influenza (dog flu) ?

 

Dog flu is a contagious respiratory disease in dogs caused by a specific Type A influenza virus referred to as a “canine influenza virus.” This is a disease of dogs, not of humans.

What is a canine influenza virus?

 

The “canine influenza virus” is an influenza A H3N8 influenza virus (not a human influenza virus) that was originally an equine (horse) influenza virus. This virus has spread to dogs and can now spread between dogs.

How long has canine influenza been around?

 

The H3N8 equine influenza virus has been known to exist in horses for more than 40 years. In 2004, however, cases of an unknown respiratory illness in dogs (initially greyhounds) were reported. An investigation showed that this respiratory illness was caused by the equine influenza A H3N8 virus. Scientists believe that this virus jumped species (from horses to dogs) and has now adapted to cause illness in dogs and spread efficiently among dogs. This is now considered a new dog-specific lineage of H3N8. In September of 2005, this virus was identified by experts as “a newly emerging pathogen in the dog population” in the United States.

What are the symptoms of this infection in dogs?

 

The symptoms of this illness in dogs are cough, runny nose and fever, however, a small proportion of dogs can develop severe disease.

How serious is this infection in dogs?

 

The number of dogs infected with this disease that die is very small. Some dogs have asymptomatic infections (no symptoms), while some have severe infections. Severe illness is characterized by the onset of pneumonia. Although this is a relatively new cause of disease in dogs and nearly all dogs are susceptible to infection, about 80 percent of dogs will have a mild form of disease.

How does dog flu spread?

 

Canine influenza virus can be spread by direct contact with aerosolized respiratory secretions from infected dogs, by contact with contaminated objects, and by people moving between infected and uninfected dogs. Therefore, dog owners whose dogs are coughing or showing other signs of respiratory disease should not participate in activities or bring their dogs to facilities where other dogs can be exposed to the virus. Clothing, equipment, surfaces, and hands should be cleaned and disinfected after exposure to dogs showing signs of respiratory disease.

Is there a test for canine influenza?

 

Testing to confirm canine influenza virus infection is available at veterinary diagnostic centers. The tests can be performed using respiratory secretions collected at the time of disease onset or using two blood samples; the first collected while the animal is sick and the second 2 to 3 weeks later.

How is canine influenza treated?

 

Treatment largely consists of supportive care. This helps the dog mount an immune response. In the milder form of the disease, this care may include medication to make your dog more comfortable and fluids to ensure that your dog remains well-hydrated. Broad spectrum antibiotics may be prescribed by your veterinarian if a secondary bacterial infection is suspected.

Is there a vaccine for canine influenza?

 

Yes, an approved vaccine is available.

I had it run through my dogs in the fall of 2008. I had 4 at the time, ranging in age from 2 years to 10 years old. They all had a fever, coughed and were tired for several weeks. One of them, the 2 year old, developed pneumonia and got very sick. It was part of a doggy epidemic in the area. That experience certainly taught me to respect canine influenza.
