How to Keep Your Squishy-Face Pneumonia-Proof

Pneumonia in bulldogs and French bulldogs is way more common than in most other breeds.

Why? Because our adorable flat-faced babies come with some… special edition features. The good news? […]

Many cases are preventable—especially when caught early.

Let’s break down the Top 3 Causes of pneumonia in bulldogs

#1: Pneumonia Due To BOAS

— The Big huff & puff Trouble Maker

BOAS (Brachycephalic Obstructive Airway Syndrome) is the Queen Bee of bulldog respiratory issues.

BOAS makes it harder for bulldogs to breathe and more likely for them to

  • retch
  • reflux
  • regurgitate
  • and vomit

And all that ā€œcoming back upā€ can get aspirated (inhaled) into the lungs, leading to pneumonia

Pneumonia due to BOAS is likely to worsens with age and is associated with increased chest and abdominal pressure, as well as an increase of your bulldog vasovagal tone.

If your bulldog sounds like Darth Vader doing CrossFit, BOAS is waving hello.

#2 Pneumonia Due to MegaesophagusĀ 

The ā€œFood Pocketā€ Regurgitation Problem

Megaesophagus means part of your dog’s esophagus becomes stretched out like a little pouch. Food collects there instead of sliding smoothly into the stomach.

And what happens next? It comes right back up.

Regurgitated food = major risk for aspiration pneumonia.

What Causes Bulldog Megaesophagus?

Most often megaesophagus is due to chronic esophagitis, usually caused by:

  1. Long-term reflux (often tied to BOAS)
  2. Hiatal hernia
  3. Bulldog GERD (yes… they get it too!)

So when your bulldog ā€œspits upā€ without warning, that’s not being naughty — it may be megaesophagus warning.

#3: Pneumonia due to Post-Anesthesia Complications

— A Big One for Bulldogs

Here’s something many bulldog moms don’t know, Not all veterinary anesthesia protocols are bulldog-friendly.

Bulldogs have unique anatomy, and if pre-op, anesthesia, and recovery protocols aren’t tailored to the breed, things can go downhill FAST.

What Cause Anesthetic Pneumonia?

  • Laryngeal edema
  • Airway collapse
  • Regurgitation

Pneumonia Warning: Some vets recommend elective surgeries (like spay/neuter) before addressing BOAS, which can be risky and sometimes catastrophic.

If the bulldog airway isn’t optimized first, anesthesia can become a dangerous event rather than a routine one.
