Kennel cough, also known as canine infectious respiratory disease (CIRD) or canine infectious tracheobronchitis, is a highly contagious respiratory infection in dogs. It's commonly seen in places where dogs are in close proximity, such as kennels, dog parks, grooming salons, or shelters. This condition can affect dogs of all ages and breeds, making it important for dog owners to recognize the symptoms, understand the causes, and take preventative measures.
1. What Causes Kennel Cough?
Kennel cough is typically caused by a combination of bacteria and viruses that affect the respiratory tract. The most common culprits include:
- Bordetella bronchiseptica: A bacterium that is often associated with kennel cough. Many cases involve Bordetella, and dogs infected with it are more susceptible to viral infections.
- Canine Parainfluenza Virus: One of the most common viral contributors to kennel cough.
- Canine Adenovirus: Another virus that can cause respiratory infections in dogs.
- Canine Herpesvirus: Though less common, it can still contribute to respiratory symptoms.
Dogs usually become infected through airborne droplets (from coughing or sneezing), direct contact with infected dogs, or contaminated surfaces, such as food bowls or toys.
2. Symptoms of Kennel Cough
The main symptom of kennel cough is a persistent, dry, hacking cough that sounds like a honking goose. It can be startling to dog owners who may think their dog is choking or gagging. Other symptoms can include:
- Coughing Fits: These fits are usually worse after exercise, excitement, or pressure on the throat.
- Gagging or Retching: Dogs may try to clear their throat by retching, especially after coughing.
- Sneezing: Some dogs may experience sneezing along with their cough.
- Runny Nose: A mild nasal discharge may occur in some cases.
- Lethargy: In severe cases, dogs might appear more tired than usual.
- Loss of Appetite: Severe cases of kennel cough may lead to reduced appetite.
- Mild Fever: Some dogs may develop a low-grade fever if the infection progresses.
Most dogs with kennel cough remain bright and alert, though more severe cases can lead to pneumonia, especially in puppies, elderly dogs, or dogs with compromised immune systems.
3. Diagnosing Kennel Cough
Veterinarians typically diagnose kennel cough based on the symptoms and the dog's history of exposure to other dogs in high-risk environments. In some cases, additional tests may be needed to rule out other respiratory conditions such as pneumonia or canine influenza. These tests may include:
- Chest X-rays: To check for any signs of pneumonia or other lung-related issues.
- Throat Swabs or Nasal Samples: To identify the bacteria or viruses causing the infection.
- Blood Tests: In rare cases, blood tests may be used to determine if the dog has a more severe infection.
4. Treatment Options for Kennel Cough
Kennel cough is usually mild and resolves on its own within 1-3 weeks. However, treatment can help alleviate symptoms and prevent complications. Common treatments include:
- Cough Suppressants: These can help reduce the intensity of coughing, making your dog more comfortable. Your vet can prescribe safe cough medications designed for dogs.
- Antibiotics: If the infection is caused by the Bordetella bacteria, or if there's a secondary bacterial infection, antibiotics may be prescribed.
- Rest: Just like humans with a cold, dogs with kennel cough need plenty of rest and minimal stress. Avoid strenuous exercise until the cough has fully resolved.
- Humidifiers: Using a humidifier or taking your dog into a steamy bathroom can help soothe irritated airways.
- Supportive Care: Ensure your dog is eating, drinking, and staying hydrated. A nutritious diet and plenty of fluids will help them recover faster.
Most dogs recover fully without any complications, but in more severe cases, particularly in puppies or immunocompromised dogs, hospitalization may be required if pneumonia develops.
5. Preventing Kennel Cough
While kennel cough can’t always be prevented, there are several steps you can take to reduce your dog's risk:
- Vaccination: The Bordetella vaccine is one of the best ways to protect your dog from kennel cough. It comes in three forms: injectable, intranasal (a spray into the nose), or oral. While the vaccine doesn’t offer 100% protection, it significantly reduces the severity of the illness if your dog does get infected. Some boarding facilities require this vaccine for entry.
- Avoid Crowded Areas: If your dog is unvaccinated, avoid taking them to places where many dogs gather, such as dog parks, daycare centers, or boarding facilities, especially during kennel cough outbreaks.
- Good Hygiene: Always wash your hands after touching other dogs, and regularly clean your dog’s bowls, bedding, and toys, especially after being in shared spaces.
- Minimize Stress: Stress can weaken your dog’s immune system, making them more susceptible to infections. Provide a calm environment for your dog, especially after traveling or boarding.
6. When to See a Vet
Most cases of kennel cough are mild and resolve with rest and supportive care. However, you should consult your vet if:
- The cough persists for more than three weeks.
- Your dog shows signs of lethargy, has a fever, or stops eating.
- The cough worsens or becomes more frequent.
- Your dog develops difficulty breathing or shows signs of respiratory distress.
In severe cases, particularly in puppies or elderly dogs, kennel cough can lead to pneumonia, which requires prompt veterinary care.
Conclusion
Kennel cough is a common and highly contagious respiratory illness in dogs, but it’s usually not serious. With proper care, most dogs recover quickly without complications. Vaccination, avoiding high-risk environments, and maintaining good hygiene are key steps to reducing your dog's risk of contracting kennel cough. If your dog shows signs of a persistent cough or any other concerning symptoms, consult your veterinarian for diagnosis and treatment.
