Transmission of Kennel Cough: How Dogs Get It

Kennel cough is a highly contagious respiratory disease that affects dogs of all ages and breeds. It can be transmitted in a variety of ways, including direct and indirect contact.

Direct Contact

Direct contact is the most common way that kennel cough is transmitted. This occurs when an infected dog comes into contact with a healthy dog. This can happen through a variety of ways, such as:

• Sharing food and water bowls;
• Playing together;
• Sniffing each other; and
• Licking each other.

When an infected dog coughs or sneezes, they release aerosolized droplets that contain the bacteria or virus that causes kennel cough. These droplets can be inhaled by a healthy dog, leading to infection.

Indirect Contact

Indirect contact occurs when a healthy dog comes into contact with a contaminated object or surface. This can happen when a healthy dog comes into contact with an object that has been contaminated by an infected dog, such as:

• Toys;
• Food and water bowls;
• Bedding; and
• Collars and leashes.

The bacteria or virus that causes kennel cough can survive on surfaces for several days, increasing the risk of transmission. When a healthy dog comes into contact with a contaminated object or surface, they can become infected if they lick or sniff the object.

It’s important to note that kennel cough can also be transmitted by humans who have come into contact with an infected dog. Humans can carry the bacteria or virus on their clothing or skin, increasing the risk of transmission to healthy dogs.

5 Most Common Ways Dogs Get Kennel Cough

Kennel cough is a highly contagious respiratory disease that is caused by a combination of bacteria and viruses. The disease is commonly found in places where dogs congregate, such as kennels, dog parks, and dog shows. Here are the most common ways dogs get kennel cough:

1. Direct Contact

The most common way dogs get kennel cough is through direct contact with an infected dog. This can happen when dogs are playing together, sharing toys or water bowls, or simply sniffing each other. The bacteria and viruses that cause kennel cough can be easily spread through the air, so even a brief encounter with an infected dog can lead to infection.

2. Contaminated Surfaces

Dogs can also get kennel cough by coming into contact with contaminated surfaces. This can include toys, food and water bowls, bedding, and even the ground. The bacteria and viruses that cause kennel cough can survive on surfaces for several hours, so it’s important to keep these areas clean and disinfected.

3. Stress

Stress can weaken a dog’s immune system, making them more susceptible to infections like kennel cough. Dogs that are in crowded or noisy environments, or those that are exposed to extreme temperatures, are more likely to develop kennel cough. It’s important to keep your dog’s stress levels low and provide them with a comfortable and safe environment.

4. Weakened Immune System

Dogs with weakened immune systems, such as puppies, older dogs, and dogs with pre-existing medical conditions, are more likely to develop kennel cough. It’s important to keep these dogs away from other dogs and to provide them with extra care and attention to help boost their immune system.

In summary, kennel cough is a highly contagious respiratory disease that can be easily spread through direct contact with infected dogs, contaminated surfaces, stress, and weakened immune systems. It’s important to take steps to prevent the spread of kennel cough and to provide your dog with a safe and comfortable environment.

Factors Increasing the Risk of Kennel Cough in Dogs

Kennel cough is a highly contagious respiratory disease in dogs, primarily caused by the bacterium Bordetella bronchiseptica and less commonly by viruses like parainfluenza. The condition can occur as a bacterial or viral infection first, and either way, it creates a weakened state that makes the respiratory tract more susceptible to a secondary infection.

The pathogens are typically spread through airborne droplets when an infected dog coughs or sneezes but can also survive on contaminated surfaces. Here are some factors that can increase your dog’s risk of developing kennel cough:

1. Crowded or Poorly Ventilated Conditions

Places like kennels, rescue centers, and shelters often house a large number of dogs in close proximity. Poor ventilation can contribute to the rapid spread of respiratory pathogens, including those causing kennel cough.

2. Social Gatherings of Dogs

Dog training classes, agility courses, or even informal gatherings facilitated by dog walkers or house sitters can be risky if any of the dogs are infected. The closer and more numerous the dogs, the higher the chances of disease spread.

3. Cold Temperatures

Cold weather can weaken a dog’s immune system and make the respiratory tract more susceptible to infection. This creates an ideal condition for kennel cough pathogens to take hold.

4. Dust and Cigarette Smoke

Exposure to irritants like dust or cigarette smoke can inflame your dog’s respiratory tract, making it easier for kennel cough bacteria or viruses to infect them.

5. Travel-Induced Stress

Stress, like that which can occur during travel, can weaken your dog’s immune system, making them more susceptible to infections like kennel cough.

Being aware of these risk factors can help you take appropriate preventative measures. While vaccines for kennel cough are available, they may not protect against all strains. Therefore, it’s crucial to combine vaccination with practical steps, like avoiding high-risk scenarios when possible, to keep your dog healthy. Always consult your veterinarian for personalized advice tailored to your dog’s specific needs.

Understanding Kennel Cough

Kennel cough, also known as canine infectious respiratory disease complex (CIRDC), is a highly contagious respiratory illness that affects dogs of all ages and breeds. The disease is caused by a combination of viruses and bacteria, including the canine parainfluenza virus, canine adenovirus, and Bordetella bronchiseptica bacteria.

Kennel cough primarily targets a dog’s upper respiratory tract, which includes the trachea (windpipe) and larynx (voice box). When the bacteria or viruses responsible for kennel cough enter the respiratory tract, they adhere to the mucosal lining and start to multiply. This causes inflammation and irritation in the affected areas.

Inflammation and Irritation

The immediate effect is usually a dry, hacking cough, often compared to the sound of a goose honk. This is a result of the inflammation and irritation in the trachea and larynx. The cough is usually worse during moments of excitement or physical activity and can be exacerbated in cold or dusty conditions.

Secondary Infections

The inflammation and irritation weaken the normal defense mechanisms of the respiratory tract, making it easier for secondary bacterial or viral infections to establish themselves. This can lead to more serious conditions like pneumonia if not treated appropriately.

Production of Mucus

The body’s response to the infection often involves producing more mucus to trap and eliminate the pathogens. However, the excess mucus can further block the airways, leading to additional symptoms like wheezing or difficulty breathing in more severe cases.

Discomfort and Lethargy

The constant coughing and general discomfort can make a dog more lethargic and less interested in food or play. This can be distressing for the pet owner and can also weaken the dog’s overall condition, making recovery slower.

Though kennel cough is generally not a severe illness in otherwise healthy dogs, its symptoms can be quite uncomfortable and can significantly impact a dog’s quality of life for the duration of the illness. Treatment often involves supportive care like cough suppressants and sometimes antibiotics for secondary bacterial infections.

Symptoms of Kennel Cough

Kennel cough, also known as canine infectious tracheobronchitis, is a highly contagious respiratory disease that affects dogs of all ages. The symptoms of kennel cough are similar to those of a common cold in humans. They include:

• A dry, hacking cough;
• Sneezing;
• Runny nose;
• Watery eyes;
• Mild fever;
• Loss of appetite; and
• Lethargy.

The cough caused by kennel cough is often described as a “honking” sound, which is a result of inflammation in the dog’s trachea and bronchi. The cough may be triggered by excitement, exercise, or pressure on the dog’s trachea.

Most dogs with kennel cough will recover within two to three weeks, but in some cases, the disease can progress to pneumonia, which can be life-threatening.

If your dog is exhibiting any of these symptoms, it’s important to take them to the vet. The vet will be able to diagnose kennel cough and prescribe the appropriate treatment.

Diagnosis of Kennel Cough

Diagnosis of kennel cough is usually based on clinical signs and history of exposure to other dogs. A veterinarian can often diagnose kennel cough based on the dog’s history of recent exposure to other dogs, a thorough physical examination, and characteristic clinical signs.

During the physical examination, the veterinarian will listen to the dog’s lungs and airways with a stethoscope to check for the characteristic cough and other abnormal sounds. The veterinarian may also perform a tracheal wash or bronchoscopy to collect samples of respiratory secretions for laboratory testing.

Laboratory testing may include bacterial cultures, viral isolation, and polymerase chain reaction (PCR) testing. Bacterial cultures may be used to identify the specific bacteria causing the infection, while viral isolation and PCR testing can identify the specific virus causing the infection.

In some cases, radiographs (x-rays) may be taken to evaluate the dog’s lungs and airways for signs of pneumonia or other complications.

It is important to note that kennel cough can have similar clinical signs to other respiratory infections, such as canine influenza or pneumonia. Therefore, it is important to consult with a veterinarian for an accurate diagnosis and appropriate treatment.

Treatment and Prevention of Kennel Cough

So, let’s look at how to treat kennel cough in dogs.

Medical Treatment

If a dog is diagnosed with kennel cough, the veterinarian may prescribe antibiotics to treat the bacterial infection. Cough suppressants may also be prescribed to help the dog feel more comfortable. In severe cases, hospitalization may be necessary to provide oxygen therapy and intravenous fluids.

Home Care

In addition to medical treatment, home care can help speed up the recovery process. It is important to keep the dog in a warm and quiet environment to minimize stress on the respiratory system. Encouraging the dog to drink plenty of water can help keep them hydrated and loosen up mucus. Humidifiers or steam from a shower can also help soothe the dog’s cough.

Preventive Measures

Preventing kennel cough is possible by minimizing exposure to infected dogs. Vaccinations are available for some of the viruses that cause kennel cough, but they do not provide complete protection. It is important to keep the dog’s immune system strong through a healthy diet and regular exercise. Avoiding crowded areas such as dog parks and boarding facilities can also reduce the risk of infection.

Complications and Risks of Kennel Cough

Kennel cough is usually a mild, self-limiting infection, but in some cases, veterinary sources point out that it can lead to more serious complications. The following are some of the possible complications and risks associated with kennel cough:

Pneumonia

In some cases, kennel cough can progress to pneumonia, which is a more serious infection of the lungs. Pneumonia can cause fever, difficulty breathing, and coughing up blood. Pneumonia can be life-threatening, especially in young puppies, older dogs, or dogs with weakened immune systems.

Bronchitis

Kennel cough can also lead to bronchitis, which is inflammation of the bronchial tubes. Bronchitis can cause coughing, wheezing, and difficulty breathing. In severe cases, bronchitis can lead to respiratory failure.

Tracheal Collapse

Dogs with a pre-existing condition known as tracheal collapse may be at a higher risk of developing complications from kennel cough. Tracheal collapse is a condition in which the trachea, or windpipe, collapses or narrows, making it difficult for the dog to breathe. Kennel cough can exacerbate this condition, leading to more severe respiratory distress. Also see: Reasons for dogs not barking.

Weakened Immune System

Dogs with a weakened immune system, such as those with cancer, diabetes, or other chronic illnesses, may be at a higher risk of developing complications from kennel cough. These dogs may have a harder time fighting off the infection and may be more susceptible to secondary infections.

Spread of Infection

Kennel cough is highly contagious and can easily spread from dog to dog. Dogs with kennel cough should be kept away from other dogs to prevent the spread of infection. In some cases, kennel cough can also be transmitted to humans, although this is rare.

It is important to monitor dogs with kennel cough for any signs of complications and to seek veterinary care if necessary. With prompt treatment, most dogs with kennel cough will make a full recovery without any long-term complications.
