The incubation period of kennel cough is a crucial factor in understanding the illness. It typically ranges from 2 to 14 days, with an average of 5-7 days.

During this time, the dog may not show any symptoms, but the virus is still contagious. This is why it's essential to keep a new dog isolated for at least 10 days after exposure to prevent the spread of the virus.

The symptoms of kennel cough usually start with a mild cough, which can progress to a more severe and persistent one. In some cases, the cough can be accompanied by a runny nose, sneezing, and loss of appetite.

Treatment options for kennel cough include antibiotics, cough suppressants, and supportive care such as plenty of rest and hydration.

What is Kennel Cough?

Kennel Cough is a highly contagious respiratory disease that affects dogs. It's caused by a type of bacteria called Bordetella bronchiseptica.

The disease is also known as infectious tracheobronchitis and is often spread through the air when an infected dog coughs or sneezes.

Symptoms and Diagnosis

Kennel cough is characterized by a dry-sounding, spasmodic cough caused by pathogens that induce inflammation of the trachea and bronchi. The cough is often followed by retching and gagging, and can be easily induced by gentle palpation of the larynx or trachea.

A dog's symptoms, history, and response to therapy are key factors in diagnosing kennel cough. However, diagnostic testing is recommended in certain cases, such as when pneumonia is suspected, or if an outbreak is occurring in multiple dogs.

The primary sign of kennel cough is a cough that sounds like a "goose honk" that may be followed by retching and gagging. If your dog is experiencing a fever, purulent nasal discharge, depression, anorexia, and a productive cough, it may indicate bronchopneumonia.

Here are some common signs and symptoms of kennel cough:

  • Characteristic cough that sounds like a "goose honk"
  • Retching and gagging
  • Fever
  • Purulent nasal discharge
  • Depression
  • Anorexia
  • Productive cough

Signs and Symptoms

The primary sign of kennel cough is a dry-sounding, spasmodic cough caused by pathogens that induce inflammation of the trachea and bronchi. This cough can be quite characteristic and is often described as sounding like a "goose honk".

A dog with kennel cough will often retch and cough up a white foamy discharge at the end of a coughing spell. This is a common symptom that can help veterinarians diagnose the condition.

Some dogs may also develop conjunctivitis, rhinitis, and a nasal discharge, but these symptoms are not as common as the cough. If you suspect your dog has kennel cough, it's essential to isolate it from other dogs and call your veterinarian.

The cough can be easily elicited by massaging the dog's larynx or trachea, which is a common diagnostic technique used by veterinarians. This is because the cough is often very characteristic and can be a key indicator of the condition.

If a dog is depressed, feverish, or expelling a thick yellow or green discharge from its nose, it may require further diagnostic tests to determine the underlying cause of the symptoms. These tests can include a complete blood count, chest x-ray, and laboratory analysis of the microorganisms inhabiting the dog's airways.

Here are some common signs that may indicate a dog has developed pneumonia or another infectious illness, such as canine distemper:

  • Depression
  • Fever
  • Thick yellow or green nasal discharge
  • Abnormal lung sounds

In these cases, diagnostic tests may be necessary to determine the underlying cause of the symptoms and provide an accurate diagnosis.

How Veterinarians Diagnose

Diagnosing kennel cough in dogs can be a bit tricky, but veterinarians have a few key steps they follow to determine if your furry friend has it. They'll typically start by looking at your dog's symptoms, history, and response to therapy.

Most of the time, veterinarians don't need to identify the underlying bacteria or virus causing the kennel cough. However, they may recommend diagnostic testing in certain situations, such as if your dog has developed pneumonia, isn't responding to supportive care, or shows signs of systemic disease.

If your dog is showing signs of pneumonia, treatment can involve a range of options, including medication to help manage the symptoms and support your dog's recovery.

Veterinarians will also use diagnostic testing to determine the severity of the disease and rule out other causes of cough. Thoracic radiographs, or X-rays of the chest, are often used to evaluate the severity of the disease and check for any signs of pneumonia.

Diagnostic testing may also involve taking swabs from your dog's throat, nose, and eyes to check for the presence of bacteria or viruses. This is typically recommended if multiple dogs are affected or if your dog is showing signs of worsening despite supportive treatment.

In some cases, veterinarians may also take a swab sample from your dog's throat, nose, or eyes for PCR testing to identify the cause of the clinical signs. This is usually recommended if your dog has developed pneumonia or if an outbreak is occurring in multiple dogs.

Contributing Organisms

Canine Infectious Respiratory Disease Complex (CIRDC) is caused by a mix of viruses and bacteria that can be contagious and spread quickly.

Some of the most common organisms that contribute to CIRDC include canine parainfluenza virus, canine adenovirus type 2, and canine influenza virus.

These viruses are often present in the environment and can survive for weeks, making it challenging to control the spread of infection.

Additional contributing organisms include Bordetella bronchiseptica, Mycoplasma species, and Streptococcus equis subspecies zooepidemicus.

Bordetella bronchiseptica is particularly concerning as it can infect both dogs and people, although cases of dog-to-human transmission are extremely rare.

Treatment and Management

For mild cases of kennel cough, treatment may only include supportive care, which focuses on rest, nutrition, and hydration. Keeping your dog's airways moist is crucial, so keeping them in the bathroom while you shower or using a humidifier in their sleep area can be beneficial.

A cough suppressant may be prescribed by your veterinarian to help reduce the frequency of the cough. This can help your dog get some much-needed rest.

Some dogs can completely recover on their own with no treatment required, but it's essential to monitor their condition and seek veterinary care if symptoms worsen.

Complicated cases of kennel cough can cause your dog to become extremely sick, so if you notice any of the following symptoms, seek veterinary care immediately: coughing, lethargy, and loss of appetite.

Hospitalization may be necessary for severe cases, and your veterinarian may prescribe intravenous fluids, antibiotics, and possibly oxygen therapy.

Here are some common antibiotics prescribed for kennel cough:

  • Amoxicillin/clavulanic acid (12–25 mg/kg, PO, every 12 hours)
  • Trimethoprim-sulfa drugs (15–30 mg/kg, PO, every 12 hours)
  • Enrofloxacin (10 mg/kg, PO, every 24 hours)
  • Doxycycline or minocycline (5–10 mg/kg, PO, every 12 hours for 7–14 days)

If your dog requires hospitalization, it's essential to house them in isolation from other animals to prevent the spread of the disease.

Frequently Asked Questions

What is the timeline of a dog with kennel cough?

Typically, dogs recover from kennel cough within 3 weeks, but in some cases, symptoms can last up to 6 weeks. Understanding the timeline is crucial for proper care and management of the condition

When is kennel cough no longer contagious?

Kennel cough is no longer contagious 7 days after symptoms have completely disappeared, but it can remain contagious for up to 14 days after symptoms resolve.
