Key facts about canine influenza (dog flu) – CDC

Canine influenza, also known as dog flu, is a contagious respiratory disease that affects dogs. Here are some key facts about this viral infection:

First identified in greyhounds in 2004

The first outbreak of canine influenza was reported in 2004 among racing greyhounds at a Florida racetrack. The virus responsible for the illness is called H3N8 and is believed to have originated from an equine influenza virus that adapted to infect dogs. Since then, it has spread to different parts of the United States.

Spreads through respiratory droplets or contaminated surfaces

Similar to human flu, canine influenza spreads easily through respiratory droplets when infected dogs cough, sneeze, or bark. It can also be transmitted indirectly through contaminated objects such as food bowls, toys, and clothing. Dogs housed together in close quarters like kennels, shelters, or doggy daycares are more susceptible to contracting the virus.

Symptoms include coughing, fever, nasal discharge, and lethargy

Dogs infected with the flu virus may exhibit symptoms such as persistent coughing that can last for several weeks. They may also have a high fever accompanied by nasal discharge and sneezing. In some cases, dogs may become lethargic and lose their appetite. Severe infections can lead to pneumonia or exacerbate existing respiratory conditions.

To determine if a dog has canine influenza, veterinarians can perform tests on respiratory secretions or blood samples. Early detection is crucial for prompt treatment and preventing further spread of the virus.

Canine influenza in different states across the United States

Since its initial identification in greyhounds back in 2004, canine influenza has been reported in various states across the United States. Outbreaks have occurred sporadically over the years in different regions. It’s important for dog owners to stay informed about the prevalence of dog flu in their area and take necessary precautions to protect their pets.

Testing and Diagnosing Canine Influenza

Testing and diagnosing the disease is crucial for effective treatment. Veterinary consultation is necessary to accurately diagnose respiratory infections in dogs.

Nasal or Throat Swab for Diagnostic Testing

One common method used to test for canine influenza is through nasal or throat swabs. These swabs are non-invasive and can be easily performed by a veterinarian or trained technician. The sample collected from the swab contains cells and secretions from the respiratory tract that may contain the virus.

Once the sample is obtained, it is sent to an animal health diagnostic center or veterinary diagnostic laboratory for further analysis. The laboratory technicians will examine the sample under a microscope to check for any signs of infection. They will also perform specific tests to detect the presence of the virus.

PCR Tests for Detection

PCR (Polymerase Chain Reaction) tests are highly sensitive and can detect even small amounts of viral genetic material in a sample. This makes them particularly useful in diagnosing canine influenza. PCR tests work by amplifying specific segments of DNA from the virus, allowing for its detection.

During a PCR test, laboratory technicians extract genetic material from the nasal or throat swab sample collected from an infected dog. They then use specialized equipment to amplify and analyze this genetic material. If viral DNA is present in the sample, it will be detected by this test.

PCR tests not only confirm if a dog has been infected with canine influenza but also help identify which strain of the virus they have contracted. This information is essential for determining appropriate treatment options and implementing preventive measures.

Veterinary Consultation: Ensuring Accurate Diagnosis

While at-home testing kits may be available on the market, it is crucial to consult a veterinarian for accurate diagnosis of canine influenza. A veterinary professional has the knowledge and experience to interpret test results correctly and provide appropriate guidance.

When visiting a veterinarian, be prepared to provide information about your dog’s symptoms, such as fever, cough, nasal discharge, or runny nose. These details will assist the veterinarian in making an accurate diagnosis.

A thorough physical examination will be conducted by the veterinarian to assess your dog’s overall health and look for any additional signs of respiratory illness. This comprehensive approach ensures that other possible causes of respiratory symptoms are ruled out before confirming a diagnosis of canine influenza.
