What Is Kennel Cough?

Kennel cough, also known as canine infectious tracheobronchitis, is a highly contagious respiratory disease that affects dogs. It’s characterized by a persistent, hacking cough that can last for days or weeks. This condition is often compared to the common cold in humans due to its widespread nature and typical mild severity.

Causes

Kennel cough is primarily caused by a combination of pathogens:

• Bacteria: Bordetella bronchiseptica is the most common bacterial cause
• Viruses: Canine adenovirus type 2 and parainfluenza virus often contribute

These pathogens work together to inflame the dog’s upper respiratory system, leading to the characteristic symptoms.

Symptoms

The main symptoms of kennel cough include:

• A loud, honking cough (often described as sounding like a goose)
• Sneezing
• Runny nose
• Lethargy
• Fever (in some cases)

While most dogs remain alert and active even though the cough, the persistent hacking can be bothersome and disruptive to both the dog and its owners.

Transmission

Kennel cough spreads rapidly in environments where dogs congregate, such as:

• Kennels
• Dog parks
• Boarding facilities
• Grooming salons
• Dog daycare centers
• Veterinary waiting rooms and wards

The disease is transmitted through:

1. Direct contact with an infected dog’s cough or sneeze
2. Contact with contaminated surfaces or objects (e.g., food bowls, toys)
3. Airborne droplets

The highly contagious nature of kennel cough means that if one dog in a household becomes infected, other dogs in the same environment are likely to contract the disease as well.

While kennel cough can be a nuisance, it’s important to note that most cases resolve on their own within a few days to weeks. But, young puppies, older dogs, and those with compromised immune systems may be at higher risk for more severe complications, such as pneumonia. In these cases, veterinary intervention may be necessary to manage symptoms and prevent secondary infections.

Understanding the Kennel Cough Vaccine

Kennel cough vaccines protect dogs against a contagious respiratory disease caused by various pathogens. These vaccines target the most common culprits: Bordetella bronchiseptica bacteria and canine parainfluenza virus.

Types of Vaccines Available

Two primary types of kennel cough vaccines are available:

• Intranasal (IN) Vaccines:

• Administered directly into the nostrils
• Provide rapid, localized mucosal protection
• Contain live, attenuated strains of B. bronchiseptica
• May include canine parainfluenza virus and canine adenovirus
• Develop protective immunity within 4 days of a single dose

• Oral Vaccines:

• Given orally
• Highly effective in preventing disease
• Reduce shedding of B. bronchiseptica

Some vaccines, like the DA2PP vaccine, offer protection against adenovirus type 2 and parainfluenza. Bordetella vaccines are available separately and may be referred to as “Bord” in veterinary records.

How the Vaccine Works?

Kennel cough vaccines stimulate the dog’s immune system to produce antibodies against exact pathogens. The intranasal and oral vaccines work by mimicking natural infection, triggering a localized immune response in the respiratory tract.

These vaccines contain weakened or modified forms of the target pathogens, allowing the dog’s body to recognize and develop immunity without causing the actual disease. The immune system creates memory cells that can quickly respond to future infections.

While no vaccine offers complete protection, kennel cough vaccines significantly reduce the risk of infection and minimize symptom severity if infection occurs. They’re particularly effective against the most common strains of Bordetella bronchiseptica and canine parainfluenza virus.

For optimal protection, veterinarians often recommend a combination of vaccines to cover multiple pathogens associated with kennel cough. The exact vaccine protocol may vary based on the dog’s risk factors, lifestyle, and local prevalence of different strains.

Benefits of Vaccination

Kennel cough vaccination offers many advantages for dogs and their owners. Let’s explore the key benefits of this preventive measure.

Protection for Individual Dogs

Kennel cough vaccines significantly reduce the risk and severity of respiratory infections in dogs. Vaccinated dogs are more likely to experience mild symptoms if they contract kennel cough, minimizing discomfort and potential complications. The vaccine targets primary pathogens like Bordetella bronchiseptica, parainfluenza virus, and adenovirus type 2, providing comprehensive protection. Intranasal vaccines offer rapid immunity within 48-72 hours, ideal for dogs needing immediate protection. This swift response is particularly beneficial for puppies, senior dogs, and those with compromised immune systems, who are more susceptible to severe cases of kennel cough.

Preventing Outbreaks in Kennels and Shelters

Vaccination plays a crucial role in preventing widespread kennel cough outbreaks in group settings. In kennels and shelters, where dogs are in close proximity, the highly contagious nature of kennel cough can lead to rapid transmission. Vaccinated dogs are less likely to contract and spread the disease, creating a barrier against outbreaks. This protection extends to boarding facilities, dog daycare centers, and animal shelters, where maintaining a healthy environment is essential. By reducing the overall infection rate, vaccination helps minimize the economic impact of outbreaks on these facilities, including treatment costs and potential closures. Also, it contributes to the well-being of shelter animals, improving their chances of adoption by keeping them healthy.

When to Vaccinate Your Dog

Timing is crucial when vaccinating dogs against kennel cough. The optimal vaccination schedule varies depending on the dog’s age, lifestyle, and risk factors. Here’s what you need to know about vaccinating puppies and adult dogs.

Puppies vs. Adult Dogs

Puppies require early protection against kennel cough. Vaccinations typically start at 6-8 weeks of age, with intranasal vaccines administered as early as 6 weeks. These provide rapid, localized protection within 4 days of a single dose. Adult dogs at high risk of exposure, such as those attending dog shows or staying in boarding facilities, should be vaccinated before potential exposure. Intranasal vaccines offer protection within days, while subcutaneous vaccines may take 10-14 days for partial immunity. Adult dogs often need a second dose 2-4 weeks after the initial vaccination for full protection.

Frequency of Vaccination

The frequency of kennel cough vaccination depends on the dog’s risk level and the exact vaccine used. Puppies typically receive a series of vaccinations over their first few months. Adult dogs generally need annual boosters to maintain immunity. High-risk dogs, such as those frequently boarded or attending dog shows, may require more frequent vaccinations. Intranasal vaccines often provide protection for up to 12 months, while injectable vaccines may offer immunity for 6-12 months. It’s essential to consult with a veterinarian to determine the most appropriate vaccination schedule based on your dog’s individual needs and lifestyle.

Administering the Vaccine

Administering the kennel cough vaccine correctly is crucial for its effectiveness. We’ll explore the different methods of administration and their exact applications.

Oral and Injectable Options

Oral kennel cough vaccines offer a convenient and stress-free administration method. The Recombitek Oral Bordetella vaccine has demonstrated 100% protection against kennel cough in studies, with no vaccinated dogs developing spontaneous cough. This oral vaccine also significantly reduces tracheal and nasal shedding of Bordetella bronchiseptica.

Injectable kennel cough vaccines are administered subcutaneously or intramuscularly. They’re often preferred when dogs are already visiting a veterinarian for other vaccinations or medical care. The choice between oral and injectable forms depends on factors such as the dog’s age, health status, and vaccination history.

Intranasal Application

Intranasal (IN) vaccines are a common and effective method for preventing kennel cough. These vaccines typically contain Bordetella bronchiseptica and may include additional antigens like canine-parainfluenza virus and canine-adenovirus type 2. IN vaccines produce rapid, localized mucosal protection, developing protective immunity within 4 days following a single dose.

The intranasal application is particularly beneficial for puppies, senior dogs, and those with compromised immune systems due to its quick onset of immunity. This method mimics the natural route of infection, stimulating a strong immune response in the respiratory tract where kennel cough pathogens typically enter the body.

Potential Side Effects and Risks

While kennel cough vaccines are generally safe and effective, they can cause some side effects. It’s important for dog owners to be aware of these potential reactions and understand when to seek veterinary care.

Common Reactions

Kennel cough vaccines typically cause mild, short-lived side effects in dogs. These common reactions include:

• Lethargy and discomfort: Dogs may experience mild malaise, lethargy, or discomfort for 1-2 days after vaccination.
• Fever: A slight increase in body temperature is normal and usually resolves within 48 hours.
• Injection site reactions: For injectable vaccines, lumps, bumps, and tenderness at the injection site can occur.
• Respiratory symptoms: Dogs receiving intranasal vaccines may exhibit sneezing, coughing, or a runny nose for 1-2 days.
• Reduced appetite: Some dogs may eat less for a day or two following vaccination.

These reactions are generally not cause for concern and resolve on their own within a few days. But, if symptoms persist or worsen, consult a veterinarian.

Rare Complications

While uncommon, more serious reactions to kennel cough vaccines can occur:

• Allergic reactions: Symptoms include facial swelling, difficulty breathing, or hives. These require immediate veterinary attention.
• Anaphylaxis: This severe, life-threatening allergic reaction is extremely rare but requires emergency treatment.
• Prolonged respiratory issues: In some cases, dogs may experience persistent coughing or other respiratory symptoms beyond the expected timeframe.
• Immune-mediated disorders: Very rarely, vaccines can trigger immune system reactions, leading to conditions like immune-mediated hemolytic anemia.
• Neurological symptoms: In extremely rare instances, dogs may exhibit neurological issues such as seizures or changes in behavior.

It’s crucial to monitor your dog closely after vaccination and report any unusual or severe symptoms to your veterinarian promptly. While these complications are rare, early intervention can significantly improve outcomes if they do occur.

Effectiveness of the Kennel Cough Vaccine

The kennel cough vaccine is highly effective in preventing and reducing the severity of canine infectious tracheobronchitis. Studies have shown that vaccinated dogs have a significantly lower risk of contracting kennel cough and experience milder symptoms if infected.

Factors Affecting Efficacy

The effectiveness of the kennel cough vaccine depends on several factors:

• Timing: Proper vaccination timing is crucial for optimal protection. Puppies typically start their vaccination series at 6-8 weeks old.
• Type of vaccine: Intranasal vaccines provide rapid immunity within 48-72 hours, while injectable vaccines may take longer to develop protection.
• Exposure risk: Dogs in high-risk environments, such as kennels or dog shows, may require more frequent vaccinations.
• Individual immune response: Each dog’s immune system may react differently to the vaccine, affecting its overall efficacy.
• Strain coverage: The vaccine’s effectiveness varies depending on its ability to target prevalent strains of Bordetella bronchiseptica and other pathogens.

Limitations of Vaccination

While the kennel cough vaccine is highly effective, it’s important to understand its limitations:

• Incomplete protection: No vaccine provides 100% immunity against all strains of kennel cough pathogens.
• Duration of immunity: Protection may wane over time, necessitating booster shots for continued effectiveness.
• Breakthrough infections: Vaccinated dogs can still contract kennel cough, though symptoms are usually milder.
• Evolving pathogens: New strains of bacteria or viruses may emerge that aren’t covered by existing vaccines.
• Individual variations: Some dogs may not develop a strong immune response to the vaccine, reducing its effectiveness.

Even though these limitations, the kennel cough vaccine remains a crucial tool in preventing and controlling the spread of this common canine respiratory disease.

Alternatives to Vaccination

While vaccination remains the most effective protection against kennel cough, some pet owners seek alternatives. Here are other preventive measures and natural immunity boosters that can complement vaccination strategies.
