Protect Your Flat-Faced Bestie: Simple Ways to Prevent BOAS Problems

They snort, they snuggle, and they steal our hearts with their uniquely affectionate personalities. Our flat-faced companions are pure joy wrapped in wrinkles and charm.

But beneath those adorable faces lies a complex anatomy that needs special care to stay safe, healthy, and thriving.

Understanding BOAS – The Breathing Battle

Brachycephalic Obstructive Airway Syndrome (BOAS) affects breeds like Frenchies, Bulldogs, Pugs, Shih Tzus, Persians, and Exotic Shorthairs.

Narrow nostrils, soft palates extending into the airways, and tonsils under such pressure that they flip inside-out all contribute to catastrophe when it comes to breathing for these flat-faced breeds.

How Common Is BOAS?

The vast majority of these breeds suffer from the characteristics that impact their quality of life, and alarmingly, many of their families are completely unaware. Often, their snorting and snoring are mistaken for cute idiosyncrasies. 

Sleep apnoea, exercise intolerance and overheating are generally not recognised despite them being a very true reality for these breeds.

Check Your Dog’s Breathing at Home

Our short-nosed friends depend on us to notice what’s normal — and what’s not. You can perform a simple “mock” BOAS test at home to spot early warning signs.

This home test mirrors the Respiratory Function Grading Scheme (RFGS) used by accredited Australian vets.

Preparation

Choose a cool day below 25°C to prevent heat stress. Use a loose-fitting harness—never a collar—to protect your pet’s airway. Record your test for review and stop immediately if your dog slows, collapses, turns blue, or refuses to continue.

Phase 1: The Resting Check (1–2 minutes)

Before doing any activity, observe your dog whilst they are calm and resting. This gives you a baseline for how they breathe when relaxed.

• Listen for Noise: Do you hear snorting, snuffling, or a high-pitched whistle? Those sounds—called stertor or stridor—can signal airway resistance.
  
• Check the Effort: Look at their chest and sides. Are they breathing easily, or do you notice nostril flare or belly effort?
  
• Keep their head neutral: Tilting it can change how the airway sounds. Then note your findings.
  
• Score it: Quiet, effortless breathing = normal. Noisy or laboured = concerning and worth discussing with your vet.

Phase 2: The 3-Minute Exercise Test

This test shows how well your dog’s airway handles gentle activity.

• The Goal: Keep your dog active for exactly 3 minutes.
  
• The Pace: Aim for a steady trot (6.5–8 km/h) or a fast walk for unfit or older dogs.
  
• Keep it Natural: Don’t pull or push—let them move freely.
  
• Health First: Stop immediately if your dog slows, pants heavily, or their tongue turns purple-blue. These are automatic Grade III signs needing urgent vet care.

Phase 3: The Recovery Check (within 30 seconds post-exercise)

Once the 3 minutes are up, observe your dog immediately—without touching them.

• The Sound Check: Is the breathing louder or raspier than it was at rest?
  
• Watch the Stomach: Are they using their belly or ribs more to breathe?
  
• Check for “Foaming”: Foam or saliva at the mouth may signal reflux or a hiatal hernia.
  
• Recovery Time: If it takes longer than one minute for breathing to settle, seek veterinary advice.
   

  

If any appear, seek veterinary care immediately before proceeding with further testing.

Weight and Breathing – The Hidden Link

Obesity worsens airway obstruction, strains the spine, and limits recovery from illness. Flat-faced breeds need careful control, losing just 0.5–2% body weight weekly to stay safe.

Every extra kilogram adds immense pressure to their chest and back. Maintaining a lean figure is the single most powerful way to prevent pain and protect breathing.

Tip: You should feel your dog’s ribs easily without pressing, and see a gentle waist when viewed from above. Use slow-feeder bowls, smaller meals, and healthy treats like carrot slices.

The Spinal “Danger Zone”

French Bulldogs and Pugs often suffer malformed vertebrae, called hemivertebrae, leading to kyphosis or scoliosis. This doubles their risk of disc disease, altering their gait and causing pain.

When a BOAS flare triggers heavy panting, it stresses fragile spinal structures. Chronic low oxygen worsens inflammation, reducing the body’s repair ability over time.

Gentle, regular exercise helps strengthen spinal support. Hydrotherapy, controlled walks, and physiotherapy build stability without strain.

Avoid jumping on furniture and use ramps or non-slip mats to protect their back.

Your vet can assess spinal strength and guide you toward safe, pain-free mobility routines.

Skin Health Starts from Within

About 35% of flat-faced pets develop skin fold infections due to trapped moisture. Daily cleaning is vital, but nutrition is the foundation of healthy skin.

Support your pet’s skin from the inside out with:

• Omega-3 & Omega-6 fatty acids – calm inflammation and reduce itch.
• Zinc & Biotin – strengthen the skin barrier and promote healing.
• Egg-derived nutrients – soothe sensitive skin naturally.
• Probiotics – support gut-skin balance for better overall resilience.

Avoid human wipes—use vet-approved cleansers. Redness or smell means it’s time for a check-up.

Proactive Care Is Power

Flat-faced breeds thrive on early, attentive care. The smallest changes—extra snoring, longer naps, or reluctance to walk—can signal something serious.

Here’s how to stay proactive:

• Use harnesses instead of collars to protect airways.
• Maintain a lean body condition year-round.
• Keep walks short on cool mornings or evenings.
• Watch for early signs like snoring, gagging, heat sensitivity, or lethargy.

When stressed, one issue can trigger another—pain leads to panting, panting to swelling, and swelling to crisis. Acting early can prevent this cascade.

Your Next Step

Our flat-faced mates live happiest when they can breathe freely, move comfortably, and stay cool. A partnership between you and a vet is their greatest gift.
