How to Recognize and Treat BOAS in Your Pug

5 min read

Brachycephalic Obstructive Airway Syndrome (BOAS) is a significant health concern for Pug owners. This condition, characterized by the unique anatomical features of brachycephalic breeds, can severely impact a Pug's quality of life.

Understanding BOAS and recognizing its symptoms early can make a considerable difference in managing this condition effectively.

Understanding BOAS

Definition and Causes of BOAS

BOAS is a pathological condition affecting short-nosed dogs, leading to severe respiratory distress. It is caused by a combination of anatomical abnormalities including narrowed nostrils, elongated soft palate, and everted laryngeal saccules, which together obstruct normal airflow.

Why Pugs Are at Higher Risk

Pugs are particularly susceptible to BOAS due to their compact facial structure. Their flattened faces and shortened airways create a higher likelihood of respiratory obstructions and inefficiencies, making even moderate exercise potentially dangerous.

Recognizing the Symptoms of BOAS in Pugs

Early Signs to Watch For

Symptoms of BOAS can appear early in a Pug’s life. Watch for noisy breathing, snorting, and struggle to breathe after exertion. Many Pugs with BOAS also exhibit sleep apnea or restlessness due to difficulty breathing at night.

✅ Labored Breathing: Pugs with BOAS often show signs of labored breathing. This may become apparent during or after physical exertion and in hot weather, conditions that naturally increase the demand for oxygen. Owners may notice their Pugs breathing heavily, with the effort seeming disproportionately high compared to the activity level.

✅ Snoring and Noisy Sleeping: It is typical for Pugs to snore due to their brachycephalic (flat-faced) structure. However, excessive snoring or any change in the usual snoring pattern that sounds more strained or louder than usual during sleep can be indicative of BOAS. This symptom is particularly significant because it suggests that the airway obstruction persists even in rest, which can diminish sleep quality and overall health.

✅ Cyanosis: Cyanosis is manifested by a bluish discoloration of the gums or tongue and is a telltale sign of oxygen deprivation. This serious symptom indicates that BOAS is significantly impacting your Pug’s ability to breathe. Any hint of cyanosis is a signal for urgent veterinary evaluation, as it reflects critical oxygenation issues that require immediate attention.

When to Seek Veterinary Help

Immediate veterinary attention is required if your Pug shows signs of cyanosis (bluish discoloration of the tongue or gums), collapses after exercise, or has persistent breathing difficulties after minimal exertion.

✅ Frequent Gagging or Choking: While some occasional gagging or coughing can be normal, especially after drinking water too fast, frequent episodes, particularly associated with meals or physical activity, might suggest significant airway obstruction characteristic of BOAS. This symptom points to an inability of the airway to manage normal airflow, making professional assessment crucial.

✅ Reduced Exercise Tolerance: If your Pug begins to show a distinct decrease in energy, particularly during activities they previously enjoyed or could handle with ease, it might be due to the restricted air flow caused by BOAS. A marked reduction in stamina, or overt lethargy following minimal exertion, underscores the strain the condition puts on your Pug’s respiratory system.

✅ Collapse or Fainting: Perhaps the most alarming sign is an episode of collapse or fainting. This can occur if intense strain is placed on the heart and lungs that are already compromised by BOAS. Any such incident, particularly if it occurs during or immediately after physical activity, warrants emergency veterinary intervention.

✅ Difficulty Cooling Down: Dogs rely heavily on panting to regulate their body temperature. If your Pug has trouble cooling down after exposure to mild heat or seems unduly distressed by warm temperatures, it could be a sign that BOAS is impairing their ability to pant effectively. This difficulty not only impacts their comfort but can also lead to dangerous overheating, which in itself is an emergency condition.

Diagnosing BOAS in Pugs

Clinical Assessments and Diagnosis

Veterinarians will often start with a physical examination, observing the breathing patterns and checking for noisy respiration. The structure of the nostrils, throat, and mouth will be evaluated to identify typical BOAS characteristics.

Tests Involved in Confirming BOAS

Confirmatory tests might include radiographs (X-rays) to view the airways, laryngoscopy to inspect the throat, and possibly CT scans to get a more detailed look at the airway structure. These tests help determine the severity of BOAS and guide treatment options.

Treatment Options for BOAS

Surgical Treatments Explained

Surgical intervention can significantly improve airway function in Pugs. Procedures may include shortening the soft palate, widening the nostrils, or removing everted laryngeal saccules. Surgery is aimed at reducing airway resistance and improving airflow.

Non-Surgical Management Strategies

For Pugs that are not ideal candidates for surgery or for mild cases, managing BOAS can involve lifestyle changes such as avoiding excessive heat and humidity, using harnesses instead of neck collars, and maintaining an ideal body weight to reduce breathing difficulties.

Managing Your Pug's Lifestyle with BOAS

Daily Care and Routine Adjustments

Managing a Pug with BOAS involves creating a stress-free environment, avoiding overexertion, and ensuring that your pet remains calm and cool, especially in warm weather. Stress and heat can exacerbate breathing difficulties, leading to dangerous situations.

Diet and Exercise Tips for BOAS Management

Exercise should be gentle and monitored closely to avoid respiratory distress. Diet plays a crucial role; overweight Pugs are more likely to experience exacerbated symptoms, so a well-balanced, portion-controlled diet is crucial.

Long-Term Care for Pugs with BOAS

Monitoring and Ongoing Care Needs

Regular veterinary check-ups are essential to monitor the progression of BOAS and adjust care as needed. This includes assessing lung function, checking for signs of heart strain, and adapting lifestyle adjustments as your Pug ages.

Quality of Life Improvements

With proper management, Pugs with BOAS can lead comfortable lives. The goal is to minimize respiratory distress and provide a loving environment that caters to their specific needs.

Prevention of BOAS in Future Generations

Breeding Considerations

Responsible breeding practices are vital for reducing the prevalence of BOAS in Pugs. Selecting against extreme brachycephalic features and encouraging the breeding of Pugs with more moderate facial structures can help.

The Role of Genetic Testing

Advancements in genetic testing can provide breeders with tools to identify traits associated with BOAS, enabling them to make informed decisions that could help minimize the risk of BOAS in future generations.


Recognizing the signs of BOAS early and implementing effective management strategies can greatly enhance a Pug's quality of life. Collaborating with knowledgeable veterinarians and committing to ongoing care and adjustments are essential for maintaining the health and happiness of your Pug.
