Geriatric Onset Laryngeal Paralysis (GOLPP) is a neurologic condition that affects elderly dogs, typically between the ages of 8 and 13 years. It is characterized by the degeneration of the nerves responsible for controlling the muscles that move the laryngeal cartilages in the throat. This degeneration leads to respiratory obstruction and other clinical signs such as hoarseness, hind-end weakness, and loss of muscle mass. GOLPP is most commonly seen in medium to large breed dogs, including Labrador Retrievers, Newfoundlands, Borzois, Golden Retrievers, Greyhounds, German Shepherd Dogs, and Brittany Spaniels.

Diagnosis of Geriatric Onset Laryngeal Paralysis
To diagnose Geriatric Onset Laryngeal Paralysis (GOLPP), veterinarians utilize a combination of tests and examinations.
Laryngoscopy: A laryngoscopy is performed to evaluate the movement of the laryngeal cartilages, which are responsible for controlling the airway. This procedure helps determine the extent of paralysis and obstructions in the throat.
Neck and Chest X-rays: X-rays of the neck and chest are used to rule out other possible causes of respiratory distress. These images can help identify any abnormalities or blockages that may be contributing to the symptoms.
Esophagram: An esophagram is conducted to assess the functionality of swallowing. This diagnostic test involves the administration of a contrast agent and the use of X-rays or fluoroscopy to visualize the passage of fluids through the esophagus.
Neurological Examination: A comprehensive neurological examination is performed to assess the dog’s gait, reflexes, and overall neurological function. This evaluation helps determine the extent of nerve degeneration associated with GOLPP.
Nerve and Muscle Biopsies: Biopsies of the affected nerves and muscles may be taken to evaluate the degeneration present in GOLPP. These samples are analyzed under a microscope to identify any abnormalities or changes associated with the condition.
Electrodiagnostics: Electrodiagnostic tests, such as electromyography and nerve conduction testing, may be utilized to assess the function and activity of the affected nerves and muscles.
Blood Tests: Blood tests may also be conducted to evaluate the overall health of the dog and identify any underlying conditions that may be contributing to the symptoms.
By utilizing these diagnostic methods, veterinarians can accurately diagnose GOLPP and determine the most appropriate treatment plan for affected dogs.

Treatment of Geriatric Onset Laryngeal Paralysis
The main treatment for Geriatric Onset Laryngeal Paralysis (GOLPP) is arytenoid laryngoplasty surgery, also known as a “tie-back” procedure. This surgical intervention aims to improve airflow in dogs affected by GOLPP by fixing one of the laryngeal cartilages in an open position. By doing so, it alleviates the respiratory obstruction caused by the degenerated nerves.
In addition to surgery, dogs with GOLPP may also receive medications to aid with swallowing difficulties. These medications can help ensure a safe and efficient passage of food and liquids through the throat. Veterinarians may also recommend changes to the dog’s feeding habits to reduce the risk of aspiration pneumonia, a potential complication of GOLPP.
This comprehensive approach to treatment can significantly improve the breathing and overall quality of life for dogs affected by GOLPP. By addressing the underlying cause of the condition and providing supportive care, veterinarians strive to optimize the well-being of these furry companions.
“The main treatment for GOLPP is arytenoid laryngoplasty surgery, also known as a ‘tie-back’ procedure.”
Complications of “Tie-back” Surgery
Although “tie-back” surgery is an effective treatment for canine geriatric onset laryngeal paralysis (GOLPP), as with any surgical procedure, there are potential complications to be aware of. The main complication associated with “tie-back” surgery is the risk of aspiration pneumonia, which occurs in approximately 18% of cases. This risk is higher in dogs with severe esophageal dysfunction.
Aspiration pneumonia is a respiratory infection that develops when foreign material, such as food or saliva, is inhaled into the lungs. In the case of GOLPP, the risk of aspiration pneumonia is increased due to the impaired laryngeal function that prevents proper protection of the airway.
However, it is important to note that aspiration pneumonia can usually be treated successfully with medication. Antibiotics are commonly prescribed to target the infection, and supportive care, such as supplemental oxygen and chest physiotherapy, may be provided to aid in recovery. With prompt diagnosis and appropriate treatment, the majority of cases can be effectively managed.
The risk of failure of the “tie-back” surgery itself is very low when performed correctly by a skilled and experienced veterinary surgeon. The procedure involves permanently opening one of the laryngeal cartilages to improve airflow, thereby alleviating respiratory obstruction. The success rate of this surgery is generally high, with dogs experiencing significant improvement in breathing and overall quality of life.
Post-Surgery Expectations
After arytenoid laryngoplasty surgery, the most common procedure for treating canine geriatric onset laryngeal paralysis polynueropathy (GOLPP), several changes can be expected in the dog’s condition. While every case is unique, there are some common post-operative outcomes:
- Decreased Respiratory Noise: The surgery aims to improve airflow, so it is expected that the respiratory noise will decrease significantly. However, it is important to note that some noise may still be present during vigorous exercise or excitement.
- Improved Exercise Tolerance: Dogs with GOLPP often experience exercise intolerance due to respiratory obstruction. Following surgery, many dogs experience a significant improvement in exercise tolerance, allowing them to engage in physical activity with less difficulty and fatigue.
- Throat-Clearing After Eating or Drinking: It is not unusual for dogs to experience throat-clearing after eating or drinking, even after surgery. However, this symptom may improve over time with changes in feeding habits and the use of appropriate medications.
- Possible Risk of Aspiration Pneumonia: Aspiration pneumonia, a potentially serious condition resulting from the inhalation of food or fluids into the lungs, can occur after surgery. However, with timely and proper treatment, aspiration pneumonia can be addressed effectively.
Overall, the quality of life for dogs with GOLPP improves significantly after surgery. While there may still be some challenges and potential complications, the benefits of arytenoid laryngoplasty far outweigh the risks, offering these beloved pets the opportunity for a fuller and more comfortable life.
Long-Term Outlook for GOLPP
GOLPP is a progressive degenerative condition that affects dogs over time. As the disease progresses, hind-end weakness and muscle wasting become evident. Despite the neurologic degeneration, it is important to note that affected dogs do not experience pain and can still maintain a good quality of life.
Dogs with poor esophageal function may have an increased risk of developing aspiration pneumonia, a potential complication of GOLPP. However, with proper management and treatment, dogs with GOLPP can live comfortably for several years.
| Long-Term Outlook for GOLPP |
|---|
| Progressive degenerative condition |
| Hind-end weakness and muscle wasting over time |
| No pain associated with neurologic degeneration |
| Good quality of life can be maintained |
| Poor esophageal function increases the risk of aspiration pneumonia |
| Proper management and treatment allow for several years of comfortable living |

Causes and Predisposition of Laryngeal Paralysis
The underlying cause of laryngeal paralysis is not completely understood, but it is believed to involve a loss of function in the nerves that control the larynx. This condition can be part of a generalized nerve and muscle weakening syndrome called Geriatric Onset Laryngeal Paralysis Polyneuropathy (GOLPP).
Laryngeal paralysis is more commonly seen in older, large-breed dogs, with Labrador Retrievers being the most commonly affected. Other breeds that may be predisposed to laryngeal paralysis include Golden Retrievers, Newfoundlands, Great Danes, and Saint Bernards.
In some cases, laryngeal paralysis can occur congenitally in certain breeds, such as Bouviers des Flandres and Bull Terriers. These dogs may exhibit signs of laryngeal paralysis at a young age.
Laryngeal paralysis can also be associated with other medical conditions such as hypothyroidism and certain types of cancer. These underlying health issues can contribute to the development of laryngeal paralysis in dogs.
Risk Factors for Laryngeal Paralysis:
- Age: Older dogs are more susceptible to laryngeal paralysis.
- Breed: Large-breed dogs, particularly Labrador Retrievers, have a higher predisposition to laryngeal paralysis.
- Genetics: Certain breeds may have a genetic predisposition to laryngeal paralysis.
- Underlying Health Conditions: Hypothyroidism and certain cancers can increase the risk of developing laryngeal paralysis.
Understanding the causes and predisposition of laryngeal paralysis is crucial for early detection and appropriate management of the condition. By recognizing the risk factors and signs, dog owners can work closely with their veterinarians to provide the necessary care and support for their beloved pets.
Clinical Signs and Diagnosis of Laryngeal Paralysis
The clinical signs of laryngeal paralysis can vary depending on the progression of the disease. These signs can include:
- Noisy or raspy breathing
- Excess panting
- Coughing
- Gagging
- Regurgitating
- Exercise and heat intolerance
- Changes in bark
- Difficulty breathing
- Tongue or gums turning blue
Diagnosis of laryngeal paralysis typically involves a thorough physical and neurological examination. Additionally, laryngeal examination and imaging tests such as X-rays may be performed to evaluate the larynx and rule out other possible causes of the symptoms.
By identifying these clinical signs and conducting appropriate diagnostic tests, veterinarians can accurately diagnose laryngeal paralysis and develop a treatment plan to improve the dog’s quality of life.
