BOAS is caused by abnormalities in the upper airway that restrict the flow of air into the lungs. Common problems include:

• Narrow nostrils (stenotic nares)
• An elongated soft palate
• Excess tissue within the airway

These changes make breathing more difficult and force affected pets to work much harder just to get enough air.

Many owners assume noisy breathing is normal for flat-faced breeds, but it can be a sign of airway obstruction.

Common signs include:

• Loud or noisy breathing
• Snoring, even while awake
• Difficulty exercising
• Excessive panting
• Gagging or retching
• Heat intolerance
• Difficulty recovering after exercise
• Collapse or breathing distress in severe cases

If you’ve noticed any of these signs, it’s worth having your pet assessed.

BOAS surgery aims to improve your pet’s ability to breathe by increasing the amount of air that can pass through the upper airway.

Depending on your pet’s condition, surgery may involve:

• Widening narrowed nostrils
• Shortening an elongated soft palate
• Correcting other airway abnormalities where appropriate

Our veterinarians will recommend the most suitable treatment based on your pet’s individual anatomy and clinical signs.

Most pets recover well following BOAS surgery, although they will require a period of rest while the airway heals.

We’ll provide detailed instructions for home care, activity restrictions and follow-up appointments, and our team will be available to answer any questions throughout your pet’s recovery.
