Do Steroids Help Dogs with Laryngeal Paralysis?
Do steroids help dogs with laryngeal paralysis? The answer is complex, but the short answer is generally no. Steroids are typically not a primary or effective long-term treatment for laryngeal paralysis in dogs, and may even be detrimental in some cases.
Understanding Laryngeal Paralysis in Dogs
Laryngeal paralysis, often referred to as “lar par,” is a condition where the cartilage flaps that open and close to allow airflow into the trachea (windpipe) become paralyzed. This paralysis prevents the larynx from opening fully during inhalation, leading to breathing difficulties, especially during exercise or hot weather. It’s most commonly seen in older, large-breed dogs, such as Labrador Retrievers, Golden Retrievers, and Saint Bernards. The condition can be life-threatening if left untreated.
Traditional Treatments for Laryngeal Paralysis
The gold standard treatment for laryngeal paralysis is surgery. The most common surgical procedure, called laryngeal tie-back, involves permanently suturing one or both of the arytenoid cartilages open to allow for easier airflow. While this surgery is generally effective, it does come with risks, including aspiration pneumonia. Other, less common surgical options exist as well.
Medical management, without surgery, typically involves:
- Weight management to reduce the strain on the respiratory system.
- Avoiding strenuous exercise, especially in hot or humid weather.
- Using a harness instead of a collar to avoid pressure on the throat.
- Sedatives and anti-anxiety medications to reduce panting and anxiety during stressful events.
- Oxygen therapy in emergency situations where breathing is severely compromised.
The Role of Steroids: Addressing Inflammation
The question “Do steroids help dogs with laryngeal paralysis?” often arises because steroids are potent anti-inflammatory drugs. While laryngeal paralysis itself is a mechanical problem caused by nerve damage (typically idiopathic, meaning of unknown cause), secondary inflammation can exacerbate the condition. Specifically, swelling around the larynx, potentially due to minor irritation or infection, could worsen the already compromised airflow.
Therefore, in some acute, emergency situations, veterinarians might administer a short course of steroids (typically corticosteroids like prednisone or dexamethasone) to reduce inflammation and temporarily improve breathing. This is not a long-term solution. The goal is to stabilize the dog for a laryngeal tie-back surgery.
Why Steroids Are Not a Long-Term Solution
Despite their anti-inflammatory properties, steroids are not considered a reliable long-term treatment for laryngeal paralysis. Several factors contribute to this:
- Steroids do not address the underlying cause: They only mask the symptoms of inflammation. The primary problem remains the paralyzed larynx.
- Side effects: Prolonged steroid use can lead to a range of significant side effects, including increased thirst and urination, weight gain, muscle weakness, increased susceptibility to infections, and the development of diabetes. These side effects often outweigh any potential benefits in the context of laryngeal paralysis.
- Lack of evidence: There is a lack of scientific evidence demonstrating the long-term efficacy of steroids in managing laryngeal paralysis. Studies consistently show that surgical intervention provides the best and most sustainable outcomes.
When Might Steroids Be Considered?
As mentioned, steroids may have a limited role in emergency situations. A veterinarian might administer a dose of steroids to help temporarily reduce airway swelling and improve breathing before surgery. This is particularly true if there is concern about secondary inflammation.
Important Considerations:
- The decision to use steroids should always be made by a veterinarian after a thorough examination.
- The dosage and duration of steroid treatment should be carefully monitored to minimize potential side effects.
- Steroids should never be used as a substitute for surgical intervention when surgery is the recommended treatment.
- Discuss all treatment options with your veterinarian, including the risks and benefits of each approach.
Common Mistakes: Reliance on Steroids Alone
A common and potentially dangerous mistake is attempting to manage laryngeal paralysis solely with steroids, without addressing the underlying mechanical issue. This can lead to a false sense of security, while the condition continues to worsen. The dog may experience sudden, life-threatening respiratory distress. Long-term steroid use also predisposes the dog to various health problems, complicating its overall health.

Frequently Asked Questions (FAQs)
Can steroids cure laryngeal paralysis in dogs?
No, steroids cannot cure laryngeal paralysis. They may provide temporary relief from inflammation, but they do not address the underlying nerve damage that causes the condition.
Are there any alternatives to surgery for laryngeal paralysis in dogs?
While surgery is the gold standard, management strategies can include weight loss, limited exercise, using a harness, and sometimes medications to control anxiety. However, these are palliative measures and do not address the root cause.
What are the potential side effects of steroid use in dogs?
Common side effects include increased thirst and urination, increased appetite, weight gain, panting, lethargy, muscle weakness, and increased risk of infections. Long-term use can also lead to diabetes, Cushing’s disease, and other serious health problems.
How quickly do steroids work to reduce inflammation in dogs?
Steroids typically begin to reduce inflammation within a few hours, but the full effects may not be seen for 24-48 hours.
Can steroids be used to prevent laryngeal paralysis?
No, there is no evidence to suggest that steroids can prevent laryngeal paralysis. The condition is usually caused by idiopathic nerve damage.
What is the best approach to manage laryngeal paralysis in dogs?
The best approach is typically a laryngeal tie-back surgery, performed by a board-certified veterinary surgeon. This procedure provides a more permanent solution by improving airflow.
Are there any natural remedies for laryngeal paralysis in dogs?
While some supplements might have anti-inflammatory properties, there is no scientific evidence to support their use in treating laryngeal paralysis. Relying solely on natural remedies is dangerous.
What is the prognosis for dogs with laryngeal paralysis after surgery?
The prognosis is generally good for dogs that undergo laryngeal tie-back surgery. Most dogs experience improved breathing and a significantly better quality of life.
How much does laryngeal tie-back surgery cost?
The cost of laryngeal tie-back surgery can vary depending on location, veterinarian, and the specific circumstances of the case. Expect to pay several thousand dollars.
What should I do if my dog is having a laryngeal paralysis attack?
Immediately take your dog to the nearest veterinary emergency clinic. Keep your dog calm and cool during transport.
Can laryngeal paralysis recur after surgery?
While laryngeal tie-back surgery is generally effective, complications can occur, and the condition can sometimes recur. This could necessitate another surgery.
How can I tell if my dog has laryngeal paralysis?
Common signs include noisy breathing (especially during inhalation), a change in bark, coughing, exercise intolerance, and a blue tinge to the gums (cyanosis) during severe episodes. If you notice these signs, consult your veterinarian immediately.
