Understanding Laryngeal Paralysis in Dogs
Laryngeal paralysis in dogs is a condition characterized by the weakening or paralysis of the muscles that control the opening and closing of the larynx, or voice box. This can lead to the collapse of the cartilage plates in the larynx, resulting in various respiratory difficulties. Let’s explore the causes, risk factors, and symptoms associated with laryngeal paralysis in dogs.
Causes and Risk Factors
Laryngeal paralysis in dogs can be caused by various factors, including:
- Idiopathic reasons: In some cases, the exact cause of laryngeal paralysis is unknown.
- Neuromuscular diseases: Certain neuromuscular conditions can contribute to the development of laryngeal paralysis.
- Tumors or lesions: Tumors or lesions in the neck or chest area can put pressure on the nerves and muscles involved in laryngeal function.
- Trauma: Injuries to the throat region can lead to laryngeal paralysis.
- Hormonal disorders: Hormonal disorders such as hypothyroidism and Cushing’s disease have been associated with laryngeal paralysis.
- Congenital issues: Certain dog breeds, including Bouvier de Flandres, Siberian Huskies, Bull Terriers, and Dalmatians, have an increased risk for the congenital form of laryngeal paralysis (Carolina Veterinary Specialists).
Symptoms and Diagnosis
Symptoms of laryngeal paralysis in dogs may vary but commonly include:
- Exercise intolerance
- Noisy breathing
- Coughing
- Gagging
- Change or loss of voice
Two characteristic audible features of laryngeal disease are a soft “ineffectual” cough and inspiratory stridor. It’s important to note that these symptoms may worsen during periods of excitement or exercise.
Diagnosing laryngeal paralysis in dogs typically involves a thorough physical examination by a veterinarian. Experienced clinicians can often detect the condition through physical examination alone, with a sensitivity of more than 90% for those familiar with the disease. However, a definitive diagnosis requires visualizing the laryngeal structure and assessing the movement of the vocal folds during respiration. This may involve techniques such as laryngoscopy or endoscopy.

Early detection and prompt diagnosis of laryngeal paralysis are crucial for determining the appropriate treatment options. If you suspect your dog may be experiencing laryngeal paralysis, it’s important to consult with a veterinarian for a comprehensive evaluation.
In the next sections, we will explore the available treatment options, including both non-surgical and surgical approaches, for managing laryngeal paralysis in dogs.
Treatment Options for Laryngeal Paralysis
When it comes to treating laryngeal paralysis in dogs, there are both non-surgical and surgical options available. The choice of treatment depends on the severity of the condition and the recommendation of the veterinarian.
Non-Surgical Treatments
For dogs with mild to moderate laryngeal paralysis, non-surgical treatments may be considered. These treatment options aim to reduce the severity of breathing difficulties and improve the dog’s quality of life. Non-surgical treatments may include:
- Anti-inflammatory drugs: These medications help reduce inflammation in the larynx, which can alleviate symptoms associated with laryngeal paralysis.
- Sedatives: Sedatives can help relax the laryngeal muscles and reduce the frequency and severity of respiratory distress.
- Antibiotics: In some cases, antibiotics may be prescribed to prevent or treat infections that can occur due to impaired laryngeal function.
- Doxepin: This medication can be used to manage coughing and throat irritation in dogs with laryngeal paralysis.
In addition to medical treatments, lifestyle adjustments can also play a role in managing laryngeal paralysis in dogs. It is advisable to avoid strenuous exercise in hot weather, as heat can exacerbate breathing difficulties. Using a harness instead of a collar during walks can also help reduce pressure on the larynx and minimize symptoms.

Surgical Solutions
Surgery is often recommended for severe cases of laryngeal paralysis in dogs. One common surgical procedure is arytenoid lateralization, also known as “tie-back” surgery. This procedure aims to tie back the collapsed cartilage on one side of the dog’s throat to prevent obstruction during breathing. According to Carolina Veterinary Specialists, this surgery has been successful in many cases and can significantly improve the dog’s quality of life.
Another surgical option for laryngeal paralysis is partial laryngectomy or laryngoplasty, which involves widening the glottal opening. These procedures may be performed individually or in combination, depending on the specific needs of the dog. The most widely used technique is arytenoid lateralization laryngoplasty, commonly referred to as a “tie back.” This procedure involves placing sutures to abduct the arytenoid cartilage, allowing for improved airflow through the larynx (dvm360).
Surgery for laryngeal paralysis in dogs should only be performed by a skilled veterinary surgeon with experience in these procedures. The veterinarian will assess the dog’s overall health and discuss the potential risks and benefits of surgery. After surgery, dogs will require a period of recovery and close monitoring. For information on post-surgery care and potential complications, please refer to the respective sections in this article.
When it comes to treating laryngeal paralysis in dogs, the choice between non-surgical and surgical options should be made in consultation with a veterinarian. Each case is unique, and the appropriate treatment plan will depend on various factors, including the dog’s overall health, the severity of the condition, and the expected prognosis.

Arytenoid Lateralization Surgery
Arytenoid lateralization surgery, commonly known as a tie back procedure, is a widely used surgical technique for treating laryngeal paralysis in dogs. The procedure aims to widen the glottal opening, allowing for improved airflow and reducing airway resistance. It involves placing sutures to abduct the arytenoid cartilage, which helps to open the airway and improve the dog’s ability to breathe.
Procedure Overview
During arytenoid lateralization surgery, the veterinarian typically performs the procedure on the left side, although this may vary based on the surgeon’s preference. Unilateral procedures are often preferred even in cases of bilateral paralysis to minimize the risk of aspiration pneumonia. It’s important to note that the degree of abduction does not need to be maximal to achieve beneficial effects (dvm360).
The surgery involves the placement of sutures to permanently position the arytenoid cartilage in an abducted position. By holding the cartilage away from the airway, the surgery helps to improve the dog’s ability to breathe and reduces respiratory distress. The sutures are carefully placed to ensure the desired level of airway opening without compromising the function of the larynx.
Benefits and Success Rates
Arytenoid lateralization surgery has shown good success rates and few complications in treating laryngeal paralysis in dogs. According to post-operative patient monitoring, the procedure has been effective in improving the dog’s breathing and quality of life (ACVS).
While there may be some changes in the dog’s bark sound following the surgery, many dogs can experience increased longevity and a good quality of life post-surgery. It’s important to note that swimming should be avoided after the procedure to reduce the risk of aspiration.
As with any surgical procedure, there are potential risks and complications associated with arytenoid lateralization surgery. However, the benefits of improved breathing and reduced respiratory distress often outweigh the risks. Some dogs may experience temporary dysphagia and coughing after the surgery, but these symptoms typically resolve with time and appropriate post-surgery care.
It’s essential to closely follow the veterinarian’s instructions for post-surgery care, which may include monitoring the dog’s feeding habits and adjusting them if necessary to reduce signs of dysphagia and coughing. Most dogs can be discharged the day after the surgery and require minimal special care. However, it’s important to note that their voices may be permanently altered post-surgery (dvm360).
Arytenoid lateralization surgery has proven to be an effective treatment option for laryngeal paralysis in dogs, providing improved breathing and an enhanced quality of life for many patients. Consult with a veterinarian to determine if this procedure is suitable for your dog and to discuss the potential risks and benefits.
Post-Surgery Care for Dogs
After undergoing laryngeal paralysis surgery, dogs require proper post-operative care to ensure a smooth recovery. This includes managing the recovery period and being aware of potential complications that may arise.
Recovery Period
Following arytenoid lateralization surgery, dogs typically have a short hospital stay and can often be discharged the day after the procedure. While recovering at home, it is important to provide a calm and quiet environment for your dog to rest and heal. Here are some key points to keep in mind during the recovery period:
- Restrict activity: Dogs should have restricted activity for approximately 2-3 weeks after surgery. This means avoiding running, jumping, or playing. Short, controlled leash walks for urination and defecation are usually sufficient during this time (Animal Clinic of Billings).
- Avoid collar or leash around the neck: Placing a collar or leash around the neck should be avoided to prevent any pressure on the surgical site. Instead, consider using a harness or a slip lead around one front leg for control and support.
- Adjust feeding habits: While most dogs can eat and drink fairly normally after surgery, some adjustments in feeding habits may be necessary. This is particularly important to reduce signs of dysphagia and cough. Consult with your veterinarian for specific recommendations tailored to your dog’s needs.
- Monitor incision site: Keep a close eye on the incision site and check for any signs of infection, such as redness, swelling, discharge, or excessive licking. If you notice any concerning changes, contact your veterinarian for guidance.
Potential Complications
While complications after laryngeal paralysis surgery are relatively rare, it is important to be aware of potential risks and complications that may arise. Some possible complications include:
- Aspiration pneumonia: Dogs undergoing arytenoid lateralization surgery have a reported significant incidence of postoperative aspiration pneumonia. This risk can be minimized by following the recommended post-operative care instructions and being vigilant for signs of respiratory distress or infection. If you notice any symptoms such as coughing, difficulty breathing, or a change in behavior, contact your veterinarian immediately.
- Change in bark sound: After surgery, some dogs may experience a change in their bark sound. This is a normal occurrence and should improve over time. If you have concerns about any persistent changes, consult your veterinarian for reassurance and guidance.
- Swimming restrictions: Dogs that have undergone laryngeal paralysis surgery should avoid swimming due to the risk of aspiration. Water entering the airway can lead to complications, so it’s essential to prevent exposure to water sources such as pools, ponds, or lakes.
It is important to follow your veterinarian’s post-operative care instructions closely and maintain regular follow-up appointments to monitor your dog’s progress. By providing proper care and attention during the recovery period, you can help ensure a successful outcome and improve your dog’s quality of life. If you have any concerns or questions about your dog’s recovery, do not hesitate to reach out to your veterinary team.
Long-Term Management
Once a dog has undergone laryngeal paralysis surgery, it is important to implement long-term management strategies to ensure their continued well-being. This involves making certain lifestyle adjustments and maintaining regular monitoring and follow-up appointments with a veterinarian.
Lifestyle Adjustments
After surgery, it is crucial to provide a suitable environment for your dog’s recovery. Restricted activity is recommended for 2-3 weeks, which means avoiding running, jumping, or engaging in strenuous play. Instead, short, controlled leash walks for urination and defecation are preferred. It is advisable to use a harness or slip lead around one front leg instead of placing a collar or leash around the neck to prevent any potential discomfort.
In terms of feeding habits, adjustments may be necessary to reduce signs of dysphagia (difficulty in swallowing) and cough. While most dogs can eat and drink normally after surgery, it is important to monitor their eating habits and make any necessary modifications to ensure their comfort and well-being.
Monitoring and Follow-Up
Regular monitoring and follow-up appointments with a veterinarian are essential to assess the dog’s progress and overall health. During these visits, the veterinarian will evaluate the dog’s breathing, voice quality, and any potential complications that may arise.
It is important to note that after arytenoid lateralization surgery, a dog’s voice may be permanently altered. This change in voice is a normal outcome of the procedure and should not be a cause for concern. However, if any new or concerning symptoms develop, such as difficulty breathing, excessive coughing, or changes in appetite, it is crucial to inform the veterinarian promptly.
Routine follow-up appointments will allow the veterinarian to monitor the dog’s progress and make any necessary adjustments to their care plan. These visits also provide an opportunity to address any questions or concerns that may arise regarding the dog’s long-term management.
By implementing these lifestyle adjustments and maintaining regular monitoring and follow-up, dog owners can provide the best possible care for their pets who have undergone laryngeal paralysis surgery. Remember, each dog’s recovery may vary, so it is important to work closely with a veterinarian to ensure the best outcome for your furry friend.
