What is Laryngeal Paralysis in Dogs

The symptoms of laryngeal paralysis in dogs are usually related to breathing difficulties and often develop gradually over time. Many owners first notice subtle changes that worsen as the condition progresses. 

Common signs include: 

• Noisy breathing (often a raspy or “roaring” sound)  

• Panting more than usual, even at rest  

• Exercise intolerance or tiring quickly  

• A change in bark (hoarse or quieter)  

• Coughing or gagging, especially when eating or drinking  

• Increased effort when breathing  

• Overheating easily  

More severe signs can include: 

• Breathing distress  

• Collapse or weakness  

• Bluish gums or tongue (low oxygen levels)  

Symptoms are often worse during exercise, excitement, or warm weather. 

If you notice any signs of breathing difficulty in your dog, it’s important to contact your vet for advice. Laryngeal paralysis often develops gradually, but early assessment can help prevent the condition from becoming more serious. 

You should arrange a check if your dog shows: 

• Noisy breathing  

• Increased panting  

• Reduced stamina  

• A change in bark  

• Coughing or gagging  

Seek urgent veterinary attention if your dog: 

• Is struggling to breathe  

• Collapses or becomes weak  

• Has pale, grey, or bluish gums  

• Is overheating and unable to cool down  

Breathing problems can deteriorate quickly, so prompt veterinary care is essential. 

Diagnosis involves assessing your dog’s clinical signs and examining the airway. Your vet will take a full history and perform a physical examination, paying close attention to breathing patterns and effort. 

A definitive diagnosis is usually made by examining the larynx under light sedation or general anaesthesia. This allows direct observation of how the larynx moves during breathing. In affected dogs, the larynx does not open properly when your dog breathes in. 

Further tests may be recommended, including: 

• Blood tests  

• Chest X-rays  

• Assessment for underlying nerve or muscle disease  

These help guide the safest and most appropriate treatment plan for your dog. 

Treatment depends on severity and overall health. The aim is to improve airflow and reduce breathing effort. 

In mild cases, or where surgery is not appropriate, management focuses on lifestyle adjustments: 

• Controlled, gentle exercise  

• Weight management  

• Avoiding heat and stress  

• Using a harness instead of a collar  

Medication may sometimes help in specific situations. 

In more severe cases, surgery is often recommended. The most common procedure is a laryngeal tie-back, where one side of the larynx is permanently held open to improve airflow. This can significantly improve breathing and quality of life. 

After surgery, dogs require: 

• Controlled recovery  

• Ongoing lifestyle management  

• Monitoring when eating and drinking  

Because one side of the airway remains open, there is a small increased risk of food or water entering the airway, which can lead to chest infections. 

Laryngeal paralysis cannot usually be prevented, particularly in older dogs where it develops as part of age-related changes. 

However, you can reduce the risk of complications by: 

• Keeping your dog at a healthy weight  

• Avoiding heat and overexertion  

• Using a harness  

• Minimising stress  

Recognising early signs and seeking veterinary advice promptly can make a significant difference. 

The outlook is often good, especially with early diagnosis and appropriate management. 

In mild cases, some dogs may be managed successfully with lifestyle changes, though monitoring is important as the condition can progress. 

Most dogs who have surgery improve significantly after and enjoy a better quality of life. 

Laryngeal paralysis in older dogs can sometimes be part of a broader age-related nerve condition. This does not affect every dog, but your vet may monitor for changes over time. 

With appropriate care, many dogs live comfortably for months to years after diagnosis.
