Kennel Cough in Pets: A Detailed Overview

Kennel cough is a common and highly contagious respiratory condition that affects dogs, and it’s known by its medical term as Canine Infectious Tracheobronchitis. This condition is especially prevalent in environments where multiple dogs are housed together, such as dog kennels, animal shelters, pet stores, and even dog parks. It causes inflammation of the trachea and bronchi, resulting in coughing, sneezing, and general respiratory discomfort. While kennel cough itself is typically not life-threatening, it can lead to serious complications in vulnerable animals, including puppies, senior dogs, and those with weakened immune systems.

This article explores the causes, symptoms, prevention, and treatment options for kennel cough, as well as addressing common questions surrounding the condition.

What is Kennel Cough?

Kennel cough refers to an umbrella term for a variety of respiratory infections that affect the upper airways in dogs. It often presents as a hacking cough, which may sound like a honking noise. Although it is more common in places where dogs are in close contact with one another, it can also occur in pets that are primarily kept indoors or outside.

Kennel cough is highly contagious and can be transmitted through:

Direct contact: between infected and healthy dogs.

Aerosol transmission: When an infected dog coughs or sneezes, droplets containing the bacteria or virus can be inhaled by nearby dogs.

Shared surfaces or environments: Such as shared bedding, water bowls, or play areas.

The condition can be caused by a combination of viral and bacterial agents. The primary pathogens responsible for kennel cough include:

Bordetella bronchiseptica: A bacterium that is one of the most common culprits.

Canine parainfluenza virus: A virus that is often found alongside other infections.

Canine adenovirus-2 and canine respiratory coronavirus: Other potential viral causes.

Mycoplasma spp.: A bacterium that may also play a role in the disease.

In many cases, kennel cough is caused by a combination of these agents, making it more challenging to treat.

Causes of Kennel Cough

As previously mentioned, kennel cough can be caused by both viral and bacterial pathogens. The presence of these pathogens, in combination with environmental factors, leads to the disease. Below are some of the most common causes:

Bordetella Bronchiseptica

Bordetella bronchiseptica is the most commonly identified bacteria in cases of kennel cough. It is a gram-negative bacterium that infects the respiratory tract and causes inflammation. It primarily affects the trachea (windpipe) and bronchi (air passages), leading to coughing, sneezing, nasal discharge, and general respiratory distress.

Bordetella can be transmitted from dog to dog through inhalation of infected droplets from a coughing dog. Because of its contagious nature, it spreads easily in crowded environments such as kennels and shelters.

Canine Parainfluenza Virus

The parainfluenza virus is a significant contributor to the development of kennel cough. It weakens the dog’s respiratory defenses, making the animal more susceptible to secondary bacterial infections. This virus, which is highly contagious, causes inflammation in the dog’s respiratory tract, leading to symptoms such as a dry, honking cough, fever, nasal discharge, and lethargy.

Other Pathogens

In addition to Bordetella and parainfluenza, other viruses such as canine adenovirus-2 and canine respiratory coronavirus can contribute to kennel cough. These agents may exacerbate the condition and make it more severe.

Symptoms of Kennel Cough

The primary symptom of kennel cough is a persistent, dry cough, which is often described as a "hacking" or "honking" cough. Other symptoms may include:

Runny nose or nasal discharge (clear or cloudy).

Sneezing.

Fever (though this is not always present).

Lethargy or reduced energy levels.

Loss of appetite.

Gagging or retching after coughing.

While kennel cough generally resolves on its own within a few weeks, it is essential to monitor the dog closely. In severe cases, especially when there are underlying conditions such as pneumonia or bronchitis, additional treatment may be necessary.

Diagnosis of Kennel Cough

Diagnosing kennel cough typically involves:

Clinical examination: The veterinarian will listen for characteristic cough sounds and check for other signs of illness, such as fever and lethargy.

History of exposure: If the dog has recently been in an environment where other dogs are present, this increases the likelihood of kennel cough.

Diagnostic tests: In some cases, diagnostic tests such as blood work, cultures, or PCR tests may be needed to identify the specific pathogens responsible for the illness. These tests are especially helpful if the dog’s symptoms persist or worsen.

Treatment of Kennel Cough

In most cases, kennel cough is self-limiting and will resolve on its own within a couple of weeks. However, treatment may still be necessary, especially in cases of severe symptoms or secondary infections.

Medications

Antibiotics: If a bacterial infection like Bordetella bronchiseptica is suspected, antibiotics may be prescribed. However, antibiotics are ineffective against viral causes of kennel cough.

Cough suppressants: These may be recommended for dogs with a persistent cough that interferes with daily activities, although they are generally not used in cases of secondary bacterial infection.

Anti-inflammatory drugs: These can reduce inflammation in the respiratory tract, which helps ease coughing and breathing.

Home Care

For mild cases, there are several ways to manage kennel cough at home:

Rest and hydration: Ensure that the dog rests and has access to plenty of water.

Humidifier or steam therapy: A humidifier can help keep the airways moist and soothe irritated throats. Steam from a hot shower may also help clear congestion.

Isolation: Since kennel cough is highly contagious, isolating the affected dog from other pets is important to prevent the spread of the disease.

Hospitalization

In severe cases where the dog has developed pneumonia or another complication, hospitalization may be required for more intensive treatment, including oxygen therapy, intravenous fluids, and a more aggressive approach to managing the infection.

Prevention of Kennel Cough

Preventing kennel cough involves a combination of vaccination, good hygiene practices, and responsible pet ownership.

Vaccination

Vaccines are available for certain pathogens responsible for kennel cough, including Bordetella bronchiseptica and parainfluenza virus. The vaccine is typically given via injection or intranasal administration. Though not 100% effective in preventing the infection, the vaccine can significantly reduce the severity and duration of symptoms if a dog does contract kennel cough.

Dogs who frequently interact with other dogs in high-risk environments (kennels, parks, grooming salons, etc.) should receive the kennel cough vaccine annually. It’s advisable to speak with a veterinarian to determine the best vaccination schedule for your dog.

Hygiene

Maintaining proper hygiene is essential in reducing the spread of kennel cough. Some steps include:

Regular cleaning: of kennels, pet bedding, water bowls, and toys.

Disinfecting surfaces: regularly, especially if a dog in the area is showing signs of illness.

Limiting exposure: to other dogs that appear unwell or have recently been in contact with sick animals.

Avoiding Stress

Stress can weaken a dog’s immune system, making it more susceptible to respiratory infections. Limiting stress and ensuring your dog is in a safe, comfortable environment can help lower the risk of kennel cough.

Complications and Risk Factors

While kennel cough is generally a mild illness, it can lead to complications in certain cases. These complications include:

Pneumonia: If the infection spreads to the lower respiratory tract, pneumonia can develop, which is a potentially life-threatening condition.

Secondary bacterial infections: Dogs with a weakened immune system are more susceptible to additional infections.

At-risk dogs include:

Puppies and senior dogs, whose immune systems are less effective.

Dogs with underlying health conditions, such as heart disease or respiratory issues.

Dogs with compromised immune systems, such as those undergoing chemotherapy or recovering from surgery.

Conclusion

Kennel cough is a highly contagious respiratory infection that primarily affects dogs in environments where they come into close contact with one another. It is caused by a combination of viral and bacterial agents, with Bordetella bronchiseptica being the most common culprit. While kennel cough is usually a mild illness that resolves on its own, some dogs may experience more severe symptoms or complications. Vaccination, good hygiene, and minimizing exposure to other dogs can help reduce the risk of infection. Treatment is often supportive, with antibiotics, cough suppressants, and anti-inflammatory drugs being used in more severe cases. Early intervention can prevent complications, and proper care and attention will allow most dogs to recover fully.
