What is Canine Influenza?

Canine influenza is a respiratory infection caused by specific influenza A viruses. These viruses can be further categorized into different strains based on their protein structures. The two most common strains affecting dogs are:

• Canine influenza virus (H3N8): This strain was first identified in racing greyhounds in Florida in 2004 and has since become widespread across the United States.
• Canine influenza virus (H3N2): This strain originated in Asia and emerged in the United States in 2015.

Signs and Symptoms of Canine Influenza

The signs and symptoms of canine influenza can vary depending on the severity of the infection, the dog’s age, and overall health. Common symptoms include:

• Coughing (often a dry, hacking cough)
• Fever
• Runny nose or nasal discharge
• Lethargy
• Loss of appetite
• Sneezing
• Difficulty breathing (in severe cases)

If you notice any of these signs in your dog, especially after they have been around other dogs, it’s important to contact your veterinarian right away. Early diagnosis and treatment can help prevent complications and shorten the duration of the illness.

Canine Influenza Vaccine Types and Efficacy

There are currently two main types of canine influenza vaccines available:

• Bivalent vaccine: This vaccine protects against both the H3N8 and H3N2 strains of canine influenza.
• H3N2-specific vaccine: This vaccine only protects against the H3N2 strain.

The efficacy of canine influenza vaccines varies depending on the specific vaccine, the dog’s immune system, and the strain of virus circulating. Studies have shown that bivalent vaccines can be highly effective (around 90%) in reducing the severity of illness and viral shedding in dogs exposed to canine influenza. However, no vaccine is 100% effective, and some dogs may still experience mild symptoms even after vaccination.

Canine Influenza Vaccine Protocols and Boosters

Canine influenza vaccines are typically administered as a two-dose series, with the second dose given 2-4 weeks after the first. The initial vaccination series can begin as early as 6 weeks of age for puppies.

The need for canine influenza vaccine boosters depends on several factors, including the type of vaccine used and the dog’s risk of exposure. Currently, there is no consensus on a universal booster recommendation. Some veterinarians may recommend annual boosters, while others may recommend boosters based on individual risk factors. Consulting with your veterinarian is essential to determine the best vaccination protocol for your dog.

Risks and Side Effects of Canine Influenza Vaccine

Canine influenza vaccines are generally considered safe for healthy dogs. The most common side effects are mild and short-lived, such as:

• Soreness at the injection site
• Mild fever
• Lethargy

In rare cases, more serious reactions like allergic reactions can occur. If you notice any concerning signs after your dog receives a canine influenza vaccine, contact your veterinarian immediately.

Who Should Get a Canine Influenza Vaccine?

The decision of whether or not to vaccinate your dog against canine influenza depends on several factors, including:

• Age: Puppies, senior dogs, and dogs with weakened immune systems are more susceptible to severe illness from canine influenza and may benefit from vaccination.
• Lifestyle: Dogs who frequently socialize with other dogs at boarding facilities, dog parks, doggy daycare, grooming salons, or other places where dogs congregate are at higher risk of exposure and may benefit from vaccination.
• Travel: Dogs who travel frequently, especially to areas with known outbreaks of canine influenza, may benefit from vaccination.
• Overall health: Dogs with underlying health conditions are more susceptible to complications from canine influenza and may benefit from vaccination after consulting with a veterinarian.

Canine Influenza Vaccine Schedule

The recommended canine influenza vaccine schedule for most dogs involves a two-dose series:

• First dose: Administered as early as 6 weeks of age for puppies.
• Second dose: Given 2-4 weeks after the first dose.

Booster vaccinations may be recommended depending on several factors, including the type of vaccine used, the dog’s risk of exposure, and your veterinarian’s advice. There is no single, universally accepted booster protocol. Some veterinarians recommend annual boosters, while others may recommend boosters based on individual risk factors. Discussing your dog’s specific needs with your veterinarian is crucial to determine the most appropriate vaccination schedule.

Canine Influenza Vaccine Price

The cost of a canine influenza vaccine can vary depending on your location, the type of vaccine used, and your veterinarian’s pricing structure. Typically, the cost falls within the range of  $30 to $80 per dose. Some veterinary clinics may offer discounts for bundled vaccinations, including the canine influenza vaccine along with other core vaccines.

Canine Influenza Vaccine Side Effects

Canine influenza vaccines are generally considered safe for healthy dogs. The most common side effects are mild and short-lived, typically resolving within a day or two. These may include:

• Soreness at the injection site
• Mild fever
• Lethargy

In rare cases, more serious reactions like allergic reactions can occur. If you notice any concerning signs after your dog receives a canine influenza vaccine, contact your veterinarian immediately.

Canine Influenza Vaccine Names

There are several commercially available canine influenza vaccines. Two of the most common brand names in the United States are:

• Nobivac Canine Flu (Intervet/Merck): This is a bivalent vaccine that protects against both the H3N8 and H3N2 strains.
• Influenza A H3N2 Canine (Zoetis): This vaccine protects specifically against the H3N2 strain.

Where to Get a Canine Influenza Vaccine

Canine influenza vaccines are typically administered by licensed veterinarians. You can schedule an appointment with your regular veterinarian to discuss the vaccine and whether it’s right for your dog. Many veterinary clinics also offer vaccination clinics where you can get your dog vaccinated without an appointment.
