Prevention involves vaccination, avoiding contact with sick dogs, and maintaining good hygiene.
What Causes Kennel Cough?
Kennel cough is a complex condition caused by a combination of viruses and bacteria. The most common culprits include:
Viral Causes:
- Bordetella bronchiseptica: This bacterium is the most common cause of kennel cough. It is highly contagious and can survive in the environment for extended periods.
- Canine adenovirus type 2 (CAV-2): This virus is also a common cause of kennel cough. It can cause severe symptoms, particularly in puppies.
- Canine parainfluenza virus (CPIV): This virus is another common cause of kennel cough. It is highly contagious and can lead to severe respiratory distress.
- Other viruses: Other viruses, such as canine distemper virus (CDV) and canine herpesvirus (CHV), can also contribute to kennel cough.
Bacterial Causes:
- Streptococcus equi: This bacterium is often involved in secondary infections associated with kennel cough.
- Mycoplasma spp.: These bacteria can also cause secondary infections in dogs with kennel cough.
Contributing Factors:
- Stress: Stressful situations, such as boarding at a kennel or being at a dog show, can weaken a dog’s immune system and make them more susceptible to kennel cough.
- Crowding: Overcrowded environments, such as kennels or shelters, can facilitate the spread of kennel cough.
- Environmental factors: Poor ventilation, cold temperatures, and dusty environments can also increase the risk of developing kennel cough.
How Is Kennel Cough Spread?
Kennel cough is highly contagious and spreads through various routes:
- Airborne droplets: Infected dogs release droplets when they cough, sneeze, or bark, which can travel through the air and infect other dogs.
- Direct contact: Dogs can become infected by direct contact with infected dogs, such as through sniffing, licking, or playing.
- Contaminated surfaces: The virus and bacteria responsible for kennel cough can survive on surfaces such as bowls, toys, bedding, and grooming tools. Dogs can become infected by coming into contact with these contaminated surfaces.
Recognizing the Symptoms of Kennel Cough
The signs and symptoms of kennel cough can vary depending on the underlying cause and the severity of the infection. However, some common symptoms include:
- Dry, hacking cough: This is often described as a “goose honk” or “whooping” cough.
- Sneezing: Dogs may sneeze frequently, particularly in the early stages of the infection.
- Runny nose: Clear or white nasal discharge is common.
- Lethargy: Dogs may appear tired and sluggish.
- Loss of appetite: Some dogs may lose interest in food.
- Difficulty breathing: In severe cases, dogs may experience difficulty breathing, such as wheezing or gasping.
- Fever: Fever is not always present, but it can occur, especially in puppies or dogs with weakened immune systems.
Differentiating Kennel Cough from Other Conditions
It’s important to note that the symptoms of kennel cough can be similar to those of other respiratory conditions, such as:
- Tracheal collapse: This condition occurs when the windpipe (trachea) collapses, causing a characteristic “honking” cough.
- Heartworm disease: In some cases, heartworm disease can cause coughing, especially when the dog is active.
- Pneumonia: This condition can also cause coughing, fever, and difficulty breathing.
If you suspect your dog has kennel cough, it’s crucial to seek veterinary attention to rule out other conditions and receive appropriate treatment.
Diagnosing Kennel Cough
Diagnosing kennel cough is typically based on:
- Clinical signs: A veterinarian will examine your dog and ask about their recent history, including any exposure to other dogs.
- Physical exam: The veterinarian will listen to your dog’s chest with a stethoscope to assess their breathing and detect any abnormal sounds.
- Nasal and throat swabs: These swabs can be used to identify the specific virus or bacteria causing the infection.
- Radiographs: X-rays can be used to evaluate the lungs and identify any signs of pneumonia.
Treatment Options for Kennel Cough
Treatment for kennel cough typically focuses on managing symptoms and preventing complications. Options may include:
- Rest: Giving your dog plenty of rest can help their body fight off the infection.
- Humidifier: A humidifier can help moisten the air and make breathing easier.
- Cough suppressants: In some cases, your veterinarian may prescribe a cough suppressant to reduce the severity of coughing.
- Antibiotics: If a bacterial infection is suspected, antibiotics may be prescribed to fight the bacteria.
- Fluid therapy: In severe cases, intravenous fluids may be needed to prevent dehydration.
Complications of Kennel Cough
While kennel cough is usually self-limiting and resolves within 2-3 weeks, some dogs may develop complications, such as:
- Pneumonia: Pneumonia is a serious complication that can occur if the infection spreads to the lungs.
- Tracheitis: Inflammation of the windpipe (trachea) can cause difficulty breathing and a persistent cough.
- Bronchitis: Inflammation of the airways can lead to chronic cough and respiratory distress.
Preventing Kennel Cough in Dogs
Prevention is key when it comes to kennel cough. You can take several steps to protect your dog:
- Vaccination: Vaccination is the most effective way to prevent kennel cough. There are two main types of kennel cough vaccines:
- Bordetella bronchiseptica vaccine: This vaccine protects against the bacterium that is most commonly associated with kennel cough.
- Combined vaccine: This vaccine protects against both Bordetella bronchiseptica and other viruses, such as parainfluenza virus and adenovirus.
- Avoid contact with sick dogs: Keep your dog away from dogs that are coughing or sneezing, especially if they haven’t been vaccinated.
- Maintain good hygiene: Wash your hands thoroughly after handling dogs, and disinfect surfaces that your dog may come into contact with.
- Stress management: Minimize stress in your dog’s life as much as possible.
- Regular vet checkups: Schedule regular veterinary checkups for your dog to ensure they are healthy and up-to-date on their vaccinations.

FAQ
What is Kennel Cough?
Kennel cough is a highly contagious respiratory infection common in dogs. It’s not a single disease but rather a collection of conditions caused by several viruses and bacteria. These pathogens can cause inflammation of the trachea (windpipe) and bronchi (airways) leading to coughing, gagging, and other respiratory symptoms. The name comes from the fact that the condition often spreads quickly in crowded environments like kennels and shelters.
However, it can also be transmitted in other settings where dogs come into contact, such as dog parks, groomers, or even during walks. The good news is that kennel cough is usually mild and self-limiting, meaning most dogs recover on their own. But it’s important to be aware of the symptoms and seek veterinary care if your dog becomes seriously ill.
