How Can You Tell If Your Dog Has The Flu?

Just like humans, dogs can catch the flu, and it can sometimes spread rapidly within specific areas, turning into localized outbreaks. Canine influenza, commonly referred to as dog flu, is a contagious respiratory illness caused by specific strains of the influenza virus.

Your dog may contract it through direct contact with an infected dog or by sharing the same environment. While dog flu often resembles a cold, and it can usually be cured with proper care and rest. It is important to identify if your dog has the flu early to ensure your dog recovers quickly and avoids complications.

In most cases, the canine flu really isn’t much more than a cold and can be treated with antibiotics and rest. However, sometimes it is hard to detect if your dog actually has the flu.

What Are The Symptoms of Influenza (Flu) in Dogs

Dogs that are infected with canine influenza may experience symptoms that range from mild to severe.

By recognizing the symptoms, it can help you determine the seriousness of your dog’s condition:

Mild Symptoms

Cough: Often moist but can sometimes be dry and persistent.

Nasal Discharge: Clear or slightly cloudy mucus.

Runny Eyes: Redness and watery eyes are common in some cases.

Lethargic: Dogs might seem tired or less energetic than usual.

Most mild cases will resolve on their own within two to three weeks if your dog gets the adequate rest and care. Typically, these symptoms appear after contact with an infected dog.

Severe Symptoms

High Fever: A temperature above 104°F.

Difficulty Breathing: Labored breathing or wheezing.

Coughing Blood: In severe cases, pneumonia may develop, causing your dog to cough up blood.

Severe symptoms require immediate veterinary attention as they can escalate rapidly and become life-threatening without proper treatment.

How Do Vets Diagnose Dog Flu?

Diagnosing the dog flu can be tricky since its symptoms—persistent cough, low fever, runny nose, and fatigue—mimic other respiratory illnesses like kennel cough or bronchitis.

Your veterinarian may perform diagnostic tests, such as bloodwork or nasal swabs, to confirm canine influenza. Early diagnosis is important as untreated flu can lead to secondary infections or worsen pre-existing conditions, especially in dogs with compromised immune systems.

Interestingly, canine influenza is closely related to equine influenza and may have mutated from that virus. While the illness is generally mild, dogs with weak immune systems are more vulnerable to severe forms of the flu.

How Likely Is Your Dog to Catch the Flu?

The influenza virus is contagious and spreads from dog to dog by sharing the same environment. It is generally a respiratory based illness and therefore dogs that are together for a period of time at a boarding facility, or shelter can spread it around.

Your dog could even catch it from the dog park as well even though you are outside. The virus can even be picked up through the respiratory droplets from another dog.

Your dog might also pick up the flu from other places such as the following:

Boarding Kennels: Close quarters make it easy for the virus to spread. The flu is different from kennel cough which is typically caught the same way.

Doggie Daycares: Frequent interaction among dogs can transmit the virus.

Shelters: High-density living conditions often lead to outbreaks.

The virus spreads through direct contact, shared surfaces, or airborne particles from coughs and sneezes. If an outbreak occurs in your area, it’s wise to limit your dog’s interactions with other dogs.

Preventing the Spread of Dog Flu If Your Dog Catches It

If your dog contracts the flu, it’s important to minimize contact with other dogs to prevent further transmission.

Here are some tips:

Isolation: Keep your dog away from other pets until fully recovered.

Hygiene: Regularly disinfect your dog’s living areas, bowls, and bedding.

Protective Measures: If you work with dogs in shelters or daycare facilities, wear gloves and sanitize surfaces frequently.

Treatment for Canine Influenza

Treating dog flu is similar to managing a cold in humans. While antibiotics cannot combat the flu virus itself, they may be prescribed to treat secondary bacterial infections.

For Mild Cases:

Rest: Make sure your dog gets plenty of quiet time to recover.

Fluids: Keep your dog hydrated to support their immune system.

Comfort: Use humidifiers or steam to alleviate nasal congestion.

For Severe Cases:

Veterinary Care: Hospitalization may be necessary for dogs with severe symptoms.

Aggressive Treatment: A combination of antibiotics, fluids, and supportive therapies may be used to stabilize your dog.

Prompt veterinary attention will help your dog to recover quickly and reduce the risk of complications.

Early Detection and Recovery

If your dog shows any signs of the flu, don’t hesitate to visit the vet. Early detection can make a significant difference in your dog’s recovery time and overall health. While canine influenza can be concerning, it is treatable, and most dogs recover fully with proper care.

By keeping an eye on your dog’s symptoms and taking preventative measures, it can certainly go a long way in keeping your furry friend healthy and happy.
