What is Bordetella for Dogs?

Bordetella is a common respiratory infection in dogs, often referred to as “kennel cough.” It’s caused by a bacterium called Bordetella bronchiseptica, which can lead to a variety of symptoms, including coughing, sneezing, and difficulty breathing. While usually not life-threatening, it can be uncomfortable for your dog and can be contagious to other dogs. This article will delve into the intricacies of Bordetella in dogs, exploring its causes, symptoms, diagnosis, treatment, and prevention.

What is Bordetella and How Does it Affect Dogs?

Bordetella is a bacterial infection that primarily affects the respiratory system of dogs. The bacterium Bordetella bronchiseptica is highly contagious and easily spreads among dogs in close contact, making kennels, dog parks, and shelters breeding grounds for the infection.

Causes of Bordetella in Dogs

The primary culprit behind canine bordetella is the Bordetella bronchiseptica bacterium. This bacterium, when inhaled, can colonize the upper respiratory tract, triggering an inflammatory response. While Bordetella bronchiseptica is the most common cause, other bacteria and viruses can contribute to kennel cough, creating a complex respiratory illness.

Symptoms of Bordetella in Dogs

Recognizing the symptoms of bordetella is crucial for prompt diagnosis and treatment. Some common signs include:

  • Coughing: The hallmark symptom of bordetella is a characteristic “honking” or “whooping” cough, often described as sounding like a goose.
  • Sneezing: Frequent sneezing is another indicator of bordetella.
  • Discharge from the nose and eyes: Clear or slightly yellow discharge can be observed around the eyes and nose.
  • Lethargy: Affected dogs may seem tired and lack energy.
  • Loss of appetite: Bordetella can cause a decrease in appetite.
  • Difficulty breathing: In severe cases, dogs might experience labored breathing.

It’s important to note that not all dogs exhibiting these symptoms necessarily have bordetella. Other respiratory infections can mimic the symptoms, making a proper diagnosis by a veterinarian essential.

Diagnosis of Bordetella in Dogs

A veterinarian will conduct a thorough physical examination, taking into account your dog’s history and symptoms. To confirm a diagnosis, they might recommend:

  • Nasal swab: A swab taken from the dog’s nose can be analyzed for the presence of Bordetella bronchiseptica.
  • X-rays: Chest x-rays might be done to assess the severity of the infection and rule out other conditions.
  • Blood tests: Blood tests can help identify other infections and determine the dog’s overall health.

Treatment for Bordetella in Dogs

Treatment for bordetella typically involves:

  • Rest: Allow your dog to rest and avoid strenuous activity.
  • Fluid therapy: Ensuring proper hydration is crucial, especially if your dog is experiencing a loss of appetite.
  • Antibiotics: Antibiotics are often prescribed to fight the bacterial infection.
  • Cough suppressants: Medications to alleviate coughing may be recommended.
  • Humidifier: Using a humidifier can help soothe the irritated respiratory tract.

Prevention of Bordetella in Dogs

Prevention is key to minimizing the risk of bordetella infection in your dog. Here are some effective preventive measures:

  • Vaccination: Bordetella vaccination is highly recommended for dogs, especially those that frequent kennels, shelters, dog parks, or groomers. The vaccine is typically administered intranasally, mimicking the natural route of infection.
  • Avoid contact with sick dogs: Keep your dog away from dogs exhibiting signs of respiratory illness.
  • Good hygiene: Wash your hands thoroughly after interacting with other dogs.

Bordetella in Puppies and Older Dogs

Puppies and senior dogs are particularly susceptible to bordetella infection. Puppies have developing immune systems, making them more vulnerable to infections. Older dogs, on the other hand, may have weakened immune systems, making them more prone to developing complications.

Complications of Bordetella

While bordetella is typically a mild illness, complications can arise in certain cases, particularly in puppies, senior dogs, and dogs with underlying health conditions. Potential complications include:

  • Pneumonia: Inflammation of the lungs can develop, leading to difficulty breathing.
  • Bronchitis: Inflammation of the bronchial tubes can cause persistent coughing and wheezing.
  • Tracheobronchitis: Inflammation of the trachea and bronchi can lead to a persistent, severe cough.

Bordetella and Other Respiratory Illnesses

Bordetella is often associated with other respiratory illnesses, creating a complex picture of canine respiratory disease. Viruses, such as canine adenovirus, canine distemper virus, and canine parainfluenza virus, can co-infect with bordetella, making the illness more severe.

Bordetella and Humans

While Bordetella bronchiseptica is primarily a dog pathogen, it can occasionally cause respiratory infections in humans. This is particularly relevant for individuals with weakened immune systems. However, the risk of humans contracting bordetella from dogs is relatively low.

Conclusion

Bordetella, often referred to as “kennel cough,” is a common respiratory infection in dogs. It is caused by the bacterium Bordetella bronchiseptica and can lead to coughing, sneezing, and other symptoms. While usually not life-threatening, it can be uncomfortable for your dog and can be contagious to other dogs. Vaccination, good hygiene, and avoiding contact with sick dogs are effective measures to prevent bordetella. If your dog exhibits signs of bordetella, it’s crucial to consult a veterinarian for proper diagnosis and treatment.

Frequently Asked Questions

1. What is Bordetella?

Bordetella is a highly contagious bacterial infection that affects the respiratory system of dogs. It is commonly known as “kennel cough” due to its prevalence in kennels and other dog-populated environments. The bacteria, Bordetella bronchiseptica, causes inflammation and irritation in the trachea and bronchi, leading to a characteristic cough.

While Bordetella is often mild and self-limiting, it can be particularly dangerous for puppies, senior dogs, and dogs with compromised immune systems. It can also lead to more serious respiratory issues, such as pneumonia, especially in susceptible individuals.

2. How is Bordetella spread?

Bordetella spreads primarily through direct contact with infected dogs. This can occur through sneezing, coughing, or even sharing water bowls or toys. The bacteria can also linger in the environment, potentially contaminating surfaces and remaining infectious for several days.

Dogs with Bordetella can also spread the infection indirectly through contact with humans or objects contaminated with the bacteria. This is why good hygiene practices, such as washing hands frequently and disinfecting surfaces, are essential in preventing the spread of the infection.

3. What are the symptoms of Bordetella in dogs?

The most common symptom of Bordetella is a persistent, dry, hacking cough. This cough may sound like a “goose honk” or “whooping” sound. Other symptoms may include:

  • Runny nose
  • Sneezing
  • Loss of appetite
  • Lethargy
  • Fever

While these symptoms are often mild, they can be severe in some cases, particularly in young, elderly, or immune-compromised dogs.

4. How is Bordetella diagnosed?

Diagnosis of Bordetella typically involves a physical examination, a review of the dog’s symptoms, and a nasal swab. The nasal swab will be tested for the presence of the Bordetella bacteria.

In some cases, other tests, such as chest x-rays, may be conducted to rule out other respiratory illnesses and assess the severity of the infection.

5. How is Bordetella treated?

Treatment for Bordetella typically involves supportive care, such as rest, fluids, and cough suppressants. In severe cases, antibiotics may be prescribed to help clear the infection.

It’s essential to follow your veterinarian’s instructions closely and monitor your dog’s condition. Supportive care can help to alleviate the symptoms and allow the dog’s immune system to fight off the infection.
