Bacterial Pneumonia in Dogs: All you need to know

Bacterial Pneumonia in Dogs: Does your dog have a severe cough, shortness of breath and nasty-looking pus from his nose? It’s not as cold as we thought.

Dogs, especially middle-aged to aged dogs are prone to respiratory problems. If they are not detected or treated, the result is a bad case of pneumonia.

Yes, Dogs can get Bacterial Pneumonia. If you ever have inflammation of the lungs, you know how nasty it can be.

Pneumonia is uncommon in healthy adult puppies, but dogs and senior dogs can also be at risk. Puppies and senior dogs have less effective immunity to fight off body invaders.

Causes of Bacterial Pneumonia

Bacterial pneumonia in dogs is a serious respiratory condition that can be caused by various types of bacteria. Understanding the causes and risk factors associated with this condition is essential for pet owners to help prevent and manage it effectively.

Several common respiratory bacteria can lead to bacterial pneumonia in dogs, including:

1. Bordetella bronchiseptica: This bacterium is well-known for causing Kennel Cough, a highly contagious upper respiratory infection. If left untreated, Kennel Cough can progress to pneumonia.
2. Streptococcus zooepidemicus: This bacterium can lead to respiratory infections in dogs, including pneumonia. It’s important to note that Streptococcus zooepidemicus is also a zoonotic pathogen, meaning it can be transmitted from dogs to humans.
3. Pasteurella multocida: This bacterium is often associated with bite wounds or animal-related injuries, but it can also cause respiratory infections and pneumonia in dogs.
4. Pseudomonas aeruginosa and Klebsiella pneumoniae: These are opportunistic pathogens that can infect dogs with weakened immune systems, especially those with underlying health conditions.
5. E. coli: While more commonly associated with gastrointestinal issues, E. coli can also cause respiratory infections in dogs.
6. Mycoplasma: Mycoplasma is a type of bacteria that can infect the respiratory system and contribute to pneumonia.

Several factors can increase a dog’s susceptibility to bacterial pneumonia:

1. Weakened Immune System: Dogs with compromised immune systems, whether due to age, underlying health conditions, or medications that suppress the immune system, are more vulnerable to bacterial infections, including pneumonia.
2. Metabolic Diseases: Conditions like renal failure, Cushing’s disease, diabetes, and Addison’s disease can weaken a dog’s immune system and make them more susceptible to bacterial pneumonia.
3. Environmental Factors: Exposure to lung irritants such as smoke, smog, or other environmental pollutants can increase the risk of respiratory infections, as these substances can damage the respiratory tract’s defenses.
4. Viral Infections: Viral infections like parainfluenza and distemper can weaken a dog’s respiratory defenses, making them more susceptible to secondary bacterial infections, including pneumonia.

Preventing bacterial pneumonia in dogs involves maintaining their overall health, ensuring they receive proper vaccinations, and minimizing exposure to risk factors. Regular veterinary check-ups, vaccination schedules, and a clean and safe environment can significantly reduce the chances of bacterial pneumonia.

Identifying signs Pneumonia

Here are some typical signs of pneumonia in dogs:

• Shallow, tiring or difficult to breathe.
• Rapid respiratory rate
• Lack of appetite.
• Dry, hacking cough or wet cough that brings up mucus or blood.
• Laziness.
• Green or cloudy yellow discharge from the nose (if in the upper lung).

These can also be signs of other illnesses. Whenever your dog exhibits these signs, she needs to visit a veterinarian.

Here’s a chart outlining common signs and symptoms of pneumonia in dogs:

Sign/Symptom	Description
Coughing	Persistent or worsening cough, often productive.
Rapid or Labored Breathing	Breathing is faster than normal; may be shallow or difficult.
Fever	Elevated body temperature, often accompanied by lethargy.
Nasal Discharge	Thick or purulent discharge from the nose.
Lethargy	Unusual tiredness, reluctance to move or exercise.
Loss of Appetite	Decreased interest in eating or drinking.
Weight Loss	Unexplained weight loss over a period of time.
Wheezing	High-pitched, whistling sounds during breathing.
Sneezing	Frequent sneezing, sometimes accompanied by discharge.
Cyanosis	Bluish or grayish discoloration of the mucous membranes or gums due to inadequate oxygenation.
Gagging	Frequent gagging or attempts to clear the throat.
Increased Heart Rate	Elevated heart rate (tachycardia) due to respiratory distress.
Reduced Energy	Decreased activity and overall energy levels.
Shallow Breathing	Breathing appears shallow and may be more visible.

After your veterinarian has done a physical exam and history, diagnostics for pneumonia may include a full blood panel and chest x-rays.

Once the diagnosis is confirmed, additional tests are recommended to help identify the underlying cause.

Multiple medications may be needed to treat the infection. They include antibiotics, drugs that help open the airways, and nasal decongestants that help break down mucus.

The treatment can take several weeks to be successful. Dogs with severe cases need to be hospitalized so they can receive supportive care such as intravenous fluids and oxygen.

A bad case of pneumonia is hard for a dog to fight. If the infection spreads throughout the body, other organs become inflamed, affecting their ability to function.

When things go bad, these dogs find it very difficult to recover, and their survival is in doubt.

That’s why veterinary care is a must if you notice these signs in your dog.
