Crate cough, also known as kennel cough, is a common and highly contagious respiratory infection that affects dogs. It’s not a specific disease, but rather a syndrome caused by a variety of infectious agents. Understanding crate cough – its causes, symptoms, treatment, and prevention – is crucial for any dog owner. This article aims to provide a comprehensive overview of this canine ailment.
Understanding Kennel Cough: The Basics
Kennel cough, or infectious tracheobronchitis, is characterized by inflammation of the trachea (windpipe) and bronchi (large airways) in dogs. The name “kennel cough” stems from the fact that it spreads rapidly in environments where dogs are kept in close proximity, such as kennels, dog parks, boarding facilities, and even groomers.
It’s important to remember that kennel cough isn’t typically life-threatening for healthy adult dogs, but it can be more serious in puppies, senior dogs, and dogs with compromised immune systems.
The Culprits Behind the Cough
Kennel cough is usually caused by a combination of viral and bacterial agents. Several different pathogens can contribute to the development of the condition.
The most common culprit is the bacterium Bordetella bronchiseptica. This bacterium attaches to the lining of the respiratory tract and damages the cells, making the dog more susceptible to secondary infections.
Viruses that can cause or contribute to kennel cough include:
- Canine adenovirus type 2
- Canine parainfluenza virus
- Canine influenza virus
- Canine distemper virus
- Canine herpesvirus
These viruses weaken the dog’s respiratory defenses, making them more vulnerable to bacterial infections like Bordetella. Less commonly, mycoplasmas can also play a role.
How Kennel Cough Spreads
Kennel cough is highly contagious and spreads through airborne droplets produced when infected dogs cough or sneeze. Direct contact with infected dogs, or sharing contaminated objects like water bowls or toys, can also transmit the disease.
The incubation period, the time between exposure and the onset of symptoms, is typically between 2 and 14 days. During this time, a dog can be contagious even before showing any signs of illness.
Recognizing the Symptoms of Crate Cough
The hallmark symptom of kennel cough is a persistent, forceful cough that is often described as a “goose honk.” This dry, hacking cough can be quite distressing for both the dog and the owner.
Other Common Symptoms
While the characteristic cough is the most noticeable sign, other symptoms can accompany it.
Sneezing and a runny nose are frequent occurrences. The nasal discharge can range from clear to thick and purulent, depending on the severity of the infection and the presence of secondary bacterial infections.
Some dogs may also develop a mild fever. Their temperature may be slightly elevated, indicating that their body is fighting off an infection.
Lethargy and reduced appetite can also be seen. The dog may seem tired, less energetic, and have a decreased interest in food. In mild cases, these signs might be subtle.
In severe cases, kennel cough can progress to pneumonia, a more serious lung infection. Symptoms of pneumonia include difficulty breathing, rapid breathing, and a bluish tinge to the gums (cyanosis). If these signs are observed, immediate veterinary attention is crucial.
Distinguishing Kennel Cough from Other Conditions
It’s important to differentiate kennel cough from other conditions that can cause coughing in dogs, such as heart disease, collapsing trachea, or foreign body inhalation. A veterinarian can perform a thorough examination and run diagnostic tests to determine the underlying cause of the cough.
Diagnosing Kennel Cough
Diagnosis of kennel cough is typically based on the dog’s history, clinical signs, and a physical examination.
Veterinary Examination
The veterinarian will listen to the dog’s lungs with a stethoscope to assess for abnormal lung sounds. They will also palpate the trachea to check for sensitivity, which is often present in dogs with kennel cough.
A tracheal wash, where a small amount of fluid is flushed into the trachea and then collected for analysis, can help identify the specific bacteria or viruses causing the infection.
In cases where pneumonia is suspected, chest X-rays may be taken to evaluate the lungs. These radiographs can reveal inflammation or fluid accumulation in the lungs.
Ruling Out Other Possibilities
The veterinarian will also consider other possible causes of the dog’s cough, such as heart disease, collapsing trachea, or foreign body inhalation. Additional diagnostic tests, such as blood tests or echocardiograms, may be necessary to rule out these conditions.
Treating Kennel Cough: A Comprehensive Approach
Treatment for kennel cough depends on the severity of the infection and the dog’s overall health.
Mild Cases: Supportive Care
In mild cases, kennel cough often resolves on its own within a few weeks with supportive care. Rest is crucial to allow the dog’s body to recover.
Cough suppressants may be prescribed to help relieve the coughing. These medications should only be given under the direction of a veterinarian, as they can sometimes suppress the dog’s ability to clear mucus from the airways.
Using a humidifier or vaporizer can help moisten the air and soothe the irritated airways. Steam from a hot shower can also be beneficial.
Avoid using a collar and leash during walks, as pressure on the trachea can irritate it and worsen the cough. A harness is a better option.
More Severe Cases: Antibiotics and Other Medications
In more severe cases, or if the dog is not improving with supportive care, antibiotics may be necessary to treat secondary bacterial infections. The veterinarian will choose an antibiotic that is effective against the bacteria identified in the tracheal wash, if one was performed.
In some cases, bronchodilators may be prescribed to help open up the airways and make breathing easier.
If the dog is having difficulty breathing, oxygen therapy may be needed. This can be administered in a veterinary hospital.
Home Remedies and Over-the-Counter Medications
While some home remedies, such as honey, have been suggested for soothing a cough, it’s important to consult with a veterinarian before using any home remedies or over-the-counter medications. Some human medications can be toxic to dogs.
When to Seek Veterinary Care
It’s essential to consult a veterinarian if your dog has a persistent cough, especially if it’s accompanied by other symptoms such as fever, lethargy, loss of appetite, or difficulty breathing. Puppies, senior dogs, and dogs with underlying health conditions are at higher risk for complications and should be seen by a veterinarian promptly.
Preventing Kennel Cough: Proactive Measures
Prevention is always better than cure, and there are several steps you can take to reduce your dog’s risk of contracting kennel cough.
Vaccination: A Key Preventative Measure
Vaccination is the most effective way to protect your dog from kennel cough. Vaccines are available for Bordetella bronchiseptica, canine parainfluenza virus, canine adenovirus type 2, and canine influenza virus.
The Bordetella vaccine is available in injectable, intranasal (nose drops), and oral forms. The intranasal vaccine is often preferred because it provides local immunity in the respiratory tract.
The frequency of vaccination depends on the dog’s lifestyle and risk of exposure. Dogs that are frequently exposed to other dogs in kennels, dog parks, or boarding facilities should be vaccinated more often.
Hygiene and Sanitation
Good hygiene and sanitation practices can help reduce the spread of kennel cough. Regularly clean and disinfect surfaces that dogs come into contact with, such as water bowls, food bowls, and toys.
Proper ventilation in kennels and other confined spaces can also help reduce the concentration of airborne pathogens.
Avoid overcrowding in kennels and boarding facilities. This can help reduce the risk of transmission.
Avoiding Exposure to Infected Dogs
Avoid contact with dogs that are coughing or showing signs of respiratory illness. This can help prevent your dog from contracting kennel cough.
If your dog has been diagnosed with kennel cough, isolate them from other dogs to prevent the spread of the infection.
Boosting Your Dog’s Immune System
A strong immune system can help your dog fight off infections. Feed your dog a balanced diet, provide regular exercise, and minimize stress.
Consider supplementing your dog’s diet with immune-boosting supplements, such as vitamin C or echinacea. Consult with your veterinarian before giving any supplements to your dog.
Living with Kennel Cough: Tips for Pet Owners
Caring for a dog with kennel cough can be challenging, but with proper care and attention, most dogs recover fully.
Creating a Comfortable Environment
Provide a comfortable and stress-free environment for your dog. Ensure they have a warm, quiet place to rest.
Avoid exposing your dog to smoke, dust, or other irritants that can worsen the cough.
Monitoring Your Dog’s Condition
Closely monitor your dog’s condition for any signs of worsening illness, such as difficulty breathing, fever, or loss of appetite. If you notice any of these signs, contact your veterinarian immediately.
Following Veterinary Instructions
It is crucial to follow your veterinarian’s instructions carefully regarding medication and supportive care.
Give all medications as prescribed and do not stop treatment prematurely, even if your dog seems to be improving.
Attend all follow-up appointments with your veterinarian to ensure that your dog is recovering properly.
Kennel cough can be a frustrating experience for both dogs and their owners. However, with a good understanding of the condition, prompt diagnosis, and appropriate treatment, most dogs recover fully and return to their normal, happy lives. Prevention is key, so make sure your dog is vaccinated and practice good hygiene to minimize their risk of contracting this common canine ailment.
What exactly is crate cough, and is it different from kennel cough?
Crate cough is not a separate disease; it’s simply a term sometimes used to describe kennel cough symptoms that develop or worsen when a dog is confined, such as in a crate. The confinement, poor ventilation, and stress associated with being in a crate can exacerbate the coughing and other respiratory symptoms. Think of it as kennel cough presenting more noticeably or intensely under specific environmental conditions.
Kennel cough, formally known as canine infectious tracheobronchitis, is a highly contagious respiratory infection that causes inflammation of the trachea and bronchi. It’s often caused by a combination of viruses and bacteria, with Bordetella bronchiseptica being a common culprit. Regardless of where a dog contracts it, confinement can make the symptoms seem more prominent, leading to the informal “crate cough” label.
How does kennel cough spread, and how can I prevent my dog from catching it?
Kennel cough is highly contagious and spreads primarily through airborne droplets produced when an infected dog coughs or sneezes. Direct contact, such as sharing water bowls, toys, or even petting an infected dog, can also transmit the disease. Close proximity in kennels, dog parks, grooming facilities, and training classes creates ample opportunities for transmission.
Prevention is key, and vaccination is the most effective measure. Vaccines are available for Bordetella bronchiseptica, adenovirus, and parainfluenza virus, which are common causes of kennel cough. Minimizing contact with unknown or potentially sick dogs, ensuring good ventilation in kennels and confined spaces, and maintaining overall good health in your dog can also reduce the risk of infection.
What are the typical symptoms of kennel cough, and how quickly do they appear after exposure?
The hallmark symptom of kennel cough is a persistent, dry, hacking cough, often described as a goose honk. Other symptoms may include sneezing, a runny nose, mild fever, lethargy, and loss of appetite. While most dogs with kennel cough will experience only mild symptoms, some may develop more severe complications such as pneumonia.
Symptoms typically appear within 2 to 14 days after exposure to the infectious agents. This incubation period can vary depending on the dog’s immune system and the specific pathogens involved. Early detection and veterinary care are crucial to prevent the infection from worsening and to minimize the spread to other dogs.
Can kennel cough be treated at home, or is a vet visit always necessary?
In mild cases, kennel cough may resolve on its own with rest and supportive care, such as providing a humidifier and ensuring the dog stays hydrated. Avoiding strenuous exercise and exposure to irritants like smoke and dust is also important. Honey can sometimes soothe the throat, but consult your vet before administering it.
However, a vet visit is always recommended to confirm the diagnosis, rule out other potential causes of the cough, and determine the best course of treatment. If your dog has a severe cough, fever, difficulty breathing, or is lethargic, immediate veterinary attention is crucial. Your vet may prescribe antibiotics to combat bacterial infections, cough suppressants to relieve the cough, or bronchodilators to open up the airways.
How long does kennel cough last, and when is my dog no longer contagious?
The duration of kennel cough can vary depending on the severity of the infection and the dog’s overall health. In most cases, symptoms will subside within 1 to 3 weeks with appropriate treatment. However, some dogs may continue to cough for several weeks, even after completing antibiotic therapy.
Dogs remain contagious for several weeks after the symptoms have resolved, typically around 1 to 2 weeks. Your vet can advise you on when it is safe to reintroduce your dog to other dogs. Following your vet’s recommendations and practicing good hygiene are essential to prevent further spread of the infection.
Are there any long-term complications associated with kennel cough?
In most cases, kennel cough resolves completely without any long-term complications. However, in rare instances, especially in young puppies, elderly dogs, or dogs with compromised immune systems, kennel cough can lead to more severe conditions such as pneumonia. Pneumonia can cause permanent lung damage and, in severe cases, can be fatal.
Additionally, persistent or untreated kennel cough can sometimes lead to chronic bronchitis, a long-term inflammation of the airways. This condition can cause ongoing coughing and difficulty breathing, requiring lifelong management. Therefore, prompt veterinary care is essential to minimize the risk of complications and ensure a full recovery.
Is the kennel cough vaccine completely effective, and are there different types of vaccines available?
While the kennel cough vaccine is highly effective in reducing the risk of infection and the severity of symptoms, it doesn’t guarantee complete immunity. Kennel cough can be caused by a variety of viruses and bacteria, and the vaccine typically covers the most common strains. Vaccinated dogs may still contract kennel cough, but their symptoms are usually milder and shorter in duration.
There are several types of kennel cough vaccines available, including injectable, intranasal (administered through the nose), and oral forms. Your veterinarian will recommend the most appropriate vaccine for your dog based on their individual risk factors, lifestyle, and local disease prevalence. Regular booster vaccinations are necessary to maintain protection.
