What is Kennel Cough?

Kennel Cough, also known as canine infectious tracheobronchitis, is a highly contagious respiratory disease that affects dogs. It is caused by a combination of viral and bacterial infections, with the most common culprits most dogs being the Bordetella bronchiseptica bacterium and the parainfluenza virus. The infection spreads when dogs inhale contaminated respiratory secretions from an infected animal or other dogs.

How Does Kennel Cough Affect a Dog’s Immune System?

Kennel Cough can have varying effects on a dog’s immune system depending on the severity of the infection and the overall health of the dog’s condition. In most cases, Kennel Cough is a mild respiratory illness that primarily affects the upper respiratory tract, including the trachea and bronchi. The immune system’s response to the infection aims to control and eliminate the invading viruses and bacteria.

Here’s how Kennel Cough can affect a dog’s immune system:

Immune Response Activation

When a dog is exposed to the bacteria or viruses that cause Kennel Cough, the immune system recognizes these foreign invaders as pathogens. This triggers an immune response, including the activation of immune cells like white blood cells, antibodies, and cytokines, to fight off the infection.

Inflammation

In response to the infection, the dog’s immune system causes inflammation in the respiratory tract. This inflammation can lead to the characteristic dry, persistent cough seen in certain breeds, in Kennel Cough.

Mucosal Immunity

Kennel Cough primarily targets the mucous membranes lining the respiratory tract. The immune system at these mucosal surfaces plays a crucial role in preventing the pathogens from entering the dog’s body further.

Impact on Immune-Compromised Dogs

Dogs with weakened immune systems, such wild animals such as puppies, older dogs, or those with pre-existing health conditions, may experience a more severe form of Kennel Cough.

Secondary Infections

In some cases, the primary infection of Kennel Cough can weaken the dog’s respiratory system and tract’s defenses, making it more susceptible to secondary bacterial infections. This can further challenge the dog shows immune system and lead to more severe complications.

Recovery and Immunity

The majority of dogs recover from Kennel Cough without complications or treatment. As the immune system successfully eliminates the pathogens, the dog develops immunity to those specific strains of the infection. However, it’s important to note that immunity may not be lifelong, which is why regular vaccinations are necessary elderly dogs to maintain protection.

Causes of Kennel Cough in Infected Dogs

Kennel Cough in infected dogs is primarily caused by a combination of viral and bacterial agents. The most common culprits responsible for this highly contagious respiratory disease infect dogs are:

Bordetella Bronchiseptica

This bacterium is one of the primary causes of Kennel Cough. It infects the respiratory tract, leading to inflammation of the trachea and bronchi, resulting in the characteristic dry, hacking cough.

Canine Parainfluenza Virus

The parainfluenza virus is another significant viral agent that contributes to Kennel Cough. It attacks the respiratory system, causing irritation and coughing in infected dogs young puppies.

Canine Adenovirus Type 2

This virus can weaken the pet, respiratory tract and pet’s immune defenses, making the dog more susceptible to bacterial infections intestinal parasites like Bordetella bronchiseptica.

Canine Distemper Virus

While less common, the canine distemper virus can also contribute to Kennel Cough, particularly in dogs with compromised immune systems.

Canine Influenza Virus

In regions where canine influenza is prevalent, it can be a contributing factor to Kennel Cough outbreaks.

It’s important to note that Kennel Cough is highly contagious and spreads through direct contact with respiratory secretions from an infected dog or other dogs. Dogs can contract the infection by inhaling airborne particles or through contact with contaminated surfaces, such as water, food bowls, or toys.

What are The Symptoms of Kennel Cough

The symptoms clinical signs of Kennel Cough can vary in severity and may resemble those of a common cold or respiratory infection. It is essential to recognize these signs early to seek appropriate veterinary care and prevent further transmission. The most common symptoms clinical signs of Kennel Cough include:

Persistent Dry Cough

The hallmark symptom of Kennel Cough is a dry, hacking cough that may sound like the dog is trying to clear something from its throat. The cough is often described as a “honking” sound and can be quite frequent.

Retching or Gagging

Some dogs with Kennel Cough may experience retching bloody diarrhea or gagging episodes up to three weeks or up to six weeks, particularly after coughing fits. This is the body’s attempt to clear the irritated respiratory tract.

Nasal Discharge

Infected dogs may have a clear or white nasal discharge, which is more common in cases with viral involvement.

Sneezing or Runny Nose

Sneezing can also be observed in some dogs infected with Kennel Cough, especially during the early stages of the infection.

Mild Fever

Some dogs may exhibit a mild increase in body temperature as the immune system responds to the infection.

Lethargy

Kennel Cough can make many dogs and a dog feel tired and lethargic, leading to reduced energy levels and enthusiasm.

Loss of Appetite

Infected dogs may show a decreased interest in food and water due other symptoms due to throat irritation abdominal pain and discomfort.

How Does Kennel Cough Spread?

Kennel Cough spreads through direct or indirect contact with respiratory secretions from infected dogs. The infectious agents responsible for Kennel Cough, such as the Bordetella bronchiseptica bacterium and various viruses, are highly contagious and can survive in the environment for some time. Here are the primary ways in which Kennel Cough spreads:

Airborne Transmission

When an infected dog coughs, sneezes, or even barks, tiny droplets containing the infectious agents are released into the air. These droplets can travel short distances and be inhaled by nearby dogs, leading to the transmission of the disease.

Direct Contact

Direct contact with an infected dog is one of the most common ways Kennel Cough spreads. Dogs who greet each other by sniffing, licking, or nuzzling can exchange respiratory secretions and pass on the infection.

Contaminated Surfaces

The pathogens responsible for Kennel Cough can survive on surfaces such as water bowls, toys, and kennel walls. When a healthy dog comes into contact with these contaminated objects and surfaces, they can pick up the infectious agents and become infected.

Shared Air Space

In places like kennels, shelters, dog parks, and pet daycare centers, where dogs are kept in close proximity, the airborne pathogens can easily spread from one dog to another pet to another.

Overcrowded Conditions

Overcrowding and inadequate ventilation can facilitate the rapid spread of Kennel Cough. When large groups of dogs are in confined spaces, the chances of infection increase significantly.

Human Transmission

While less common, humans can also play a role in transmitting Kennel Cough. If a person handles an infected dog and then interacts with a healthy dog without proper handwashing, they can inadvertently transfer the infectious agents to other animals.

Diagnosing Kennel Cough

Diagnosing Kennel Cough typically involves a combination of clinical signs, medical history, and physical examination by a veterinarian. Since Kennel Cough shares symptoms with other respiratory infections, a thorough evaluation is essential to rule out other potential causes.

Patient History

The veterinarian will begin by asking the dog owner about the dog’s recent activities and any possible exposure to other dogs in places like kennels, shelters, or dog parks.

Kennel Sickness: Clinical Signs

The characteristic symptoms of Kennel Cough, such as a dry, persistent cough, retching, nasal discharge, and sneezing, are essential clues for diagnosis intensive treatment. Additionally, the veterinarian will inquire about the duration and progression of these symptoms.

Kennel Sickness: Physical Examination

A thorough physical examination will be conducted to assess the dog’s overall health and look for any signs of respiratory distress or abnormalities in the throat and lungs.

Kennel Sickness: Laboratory Tests

In some cases, the veterinarian may recommend additional tests to confirm the diagnosis and rule out other potential causes of the symptoms. These tests may include tracheal swabs or nasopharyngeal swabs to collect samples from the respiratory tract.

Kennel Sickness: Differential Diagnosis

Kennel Cough shares symptoms with other respiratory infections, such as canine influenza or canine distemper. The veterinarian will consider these possibilities during the diagnosis and may perform additional tests to differentiate between them.
