A bad case of kennel cough presents with severe and persistent coughing fits, often accompanied by wheezing, lethargy, loss of appetite, and potentially pneumonia. It’s more than just a mild hacking sound; it’s a debilitating illness.

Understanding Kennel Cough

Kennel cough, formally known as canine infectious tracheobronchitis, is a highly contagious respiratory disease affecting dogs. While often mild and self-limiting, a bad case of kennel cough can be quite serious and requires prompt veterinary attention. The term “kennel cough” is actually an umbrella term, encompassing infections caused by various bacteria and viruses, often acting in combination. Bordetella bronchiseptica is the most common culprit, but others, such as canine parainfluenza virus and canine adenovirus, can also contribute.

Transmission and Risk Factors

The highly contagious nature of kennel cough makes it easily transmissible between dogs, especially in environments with close contact, such as kennels, dog parks, and grooming facilities. Transmission occurs through:

Airborne droplets produced when an infected dog coughs or sneezes.
Direct contact with an infected dog.
Contaminated surfaces such as bowls, toys, or bedding.

Risk factors for developing a bad case of kennel cough include:

Age: Puppies and older dogs are more vulnerable due to their immature or weakened immune systems.
Underlying Health Conditions: Dogs with pre-existing respiratory problems or compromised immune systems are at higher risk.
Stress: Stressful environments can weaken a dog’s immune system, making them more susceptible to infection.
Lack of Vaccination: Unvaccinated dogs are at significantly greater risk of contracting kennel cough.

Signs and Symptoms of a Bad Case

What does a bad case of kennel cough look like? It presents differently than a mild case. While a mild case might involve a dry, hacking cough, often described as a goose honk, a severe case exhibits more pronounced and concerning symptoms. These can include:

Severe, Persistent Coughing: The cough is frequent, intense, and may be productive, meaning it brings up phlegm or mucus.
Wheezing or Difficulty Breathing: Inflammation and narrowing of the airways can lead to wheezing sounds and labored breathing.
Lethargy and Weakness: Infected dogs may become extremely tired and reluctant to exercise.
Loss of Appetite: A diminished or complete loss of appetite is common.
Fever: Elevated body temperature can indicate a more serious infection.
Nasal Discharge: Thick, yellow or green nasal discharge suggests a secondary bacterial infection.
Pneumonia: In severe cases, kennel cough can progress to pneumonia, characterized by difficulty breathing, rapid breathing, and crackling sounds in the lungs.
Cyanosis: Bluish discoloration of the gums and tongue indicates a lack of oxygen and requires immediate veterinary attention.

Diagnosis and Treatment

Diagnosis typically involves a physical examination and a review of the dog’s history. The veterinarian may listen to the dog’s lungs and observe their breathing. In some cases, further diagnostic tests, such as a tracheal wash or chest X-rays, may be necessary, especially if pneumonia is suspected.

Treatment for a bad case of kennel cough is more aggressive than treatment for a mild case. It may include:

Antibiotics: To combat secondary bacterial infections.
Cough Suppressants: To provide relief from the coughing. However, these should be used cautiously as they can suppress the body’s ability to clear mucus.
Bronchodilators: To open up the airways and ease breathing.
Nebulization or Humidification: To help loosen mucus and soothe the airways.
Supportive Care: This includes providing a quiet, comfortable environment, ensuring adequate hydration, and offering palatable food. In severe cases, hospitalization and oxygen therapy may be necessary.

Prevention

Vaccination is the most effective way to prevent kennel cough. Several types of vaccines are available, including injectable, intranasal, and oral vaccines. Vaccinations don’t guarantee complete immunity, but they significantly reduce the severity and duration of the illness. Other preventive measures include:

Avoiding crowded dog environments when possible.
Practicing good hygiene by washing hands after interacting with other dogs.
Ensuring good ventilation in kennels and other dog facilities.
Minimizing stress for your dog.

Frequently Asked Questions (FAQs)

What is the incubation period for kennel cough?

The incubation period for kennel cough is typically between 2 and 14 days. This means that a dog can be infected and contagious for up to two weeks before showing any symptoms. This lengthy incubation period contributes to the rapid spread of the disease.

Is kennel cough contagious to humans?

While Bordetella bronchiseptica, the most common cause of kennel cough, is primarily a canine pathogen, it can, in very rare cases, infect humans, particularly those with weakened immune systems.

How long is a dog contagious with kennel cough?

Dogs are typically contagious for several weeks after the onset of symptoms, even after the cough has subsided. Some dogs can remain carriers of the bacteria for months, shedding it intermittently without showing any clinical signs.

Can a vaccinated dog still get kennel cough?

Yes, vaccinated dogs can still contract kennel cough, but the symptoms are usually milder and the duration of the illness is shorter. This is because the vaccine provides partial protection against the most common strains of the disease.

What should I do if I suspect my dog has kennel cough?

If you suspect your dog has kennel cough, it’s crucial to isolate them from other dogs immediately and contact your veterinarian for advice. Prompt diagnosis and treatment can prevent the condition from worsening.

Can I treat kennel cough at home?

While mild cases of kennel cough may resolve on their own with rest and supportive care, a bad case of kennel cough always requires veterinary intervention. Attempting to treat it at home can lead to complications.

Is kennel cough always a dry cough?

While the classic symptom of kennel cough is a dry, hacking cough, a bad case of kennel cough can produce a moist cough with phlegm or mucus, especially if a secondary bacterial infection is present.

What’s the difference between kennel cough and canine influenza?

Both kennel cough and canine influenza are contagious respiratory diseases, but they are caused by different pathogens. Canine influenza tends to cause more systemic signs, such as fever, lethargy, and anorexia, compared to a typical case of kennel cough.

How can I differentiate between a mild and a bad case of kennel cough?

A mild case usually involves a dry, hacking cough with no other significant symptoms. A bad case of kennel cough is characterized by severe, persistent coughing, wheezing, lethargy, loss of appetite, fever, and potentially pneumonia.

Are certain dog breeds more susceptible to kennel cough?

While all dog breeds are susceptible to kennel cough, breeds with shorter snouts (brachycephalic breeds) like Bulldogs and Pugs may experience more severe symptoms due to their already compromised airways.

What’s the role of humidity in managing kennel cough?

Humidifying the air can help to soothe the airways and loosen mucus, making it easier for the dog to cough up. A humidifier or vaporizer can be beneficial, particularly in dry environments.

What is the long-term prognosis for a dog with a bad case of kennel cough?

With prompt and appropriate veterinary treatment, the prognosis for a dog with a bad case of kennel cough is generally good. However, pneumonia or other complications can lead to a less favorable outcome. Early detection and aggressive treatment are key.
