If your dog’s breathing suddenly sounds louder, their bark has changed, or they seem to struggle more than they used to during walks or warm weather, it can be unsettling. One condition that can cause these changes, particularly in older, large-breed dogs, is laryngeal paralysis.
Laryngeal paralysis, often shortened to Lar Par, affects a dog’s ability to properly open the larynx during breathing. While the diagnosis can sound frightening, understanding what is happening and learning how to manage your dog’s activity, environment, weight, and overall comfort can make a meaningful difference in their quality of life.
What Is Laryngeal Paralysis in Dogs?
The larynx, or voice box, sits at the entrance to the trachea. During normal breathing, structures called arytenoid cartilages move outward to open the airway and allow air to pass freely into the lungs.
In dogs with laryngeal paralysis, the nerves controlling these structures stop functioning normally. Instead of opening adequately during inhalation, one or both sides of the larynx remain partially closed. This narrows the airway and makes it more difficult for the dog to move air, particularly during exercise, excitement, stress, or hot weather.
In many older dogs, laryngeal paralysis is now recognized as part of a broader neurologic condition known as geriatric-onset laryngeal paralysis polyneuropathy, or GOLPP. This means the condition may involve more than just the larynx and can eventually affect nerves elsewhere in the body.
What Dogs Are Most at Risk for Laryngeal Paralysis?
Laryngeal paralysis is most commonly diagnosed in middle-aged to senior dogs, especially large-breed dogs.
Labrador Retrievers are particularly well known for developing the condition, but it can also occur in Golden Retrievers, Newfoundlands, Saint Bernards, Irish Setters, and other breeds.
Because symptoms can develop gradually, owners sometimes assume their dog is simply slowing down with age. Recognizing the early signs can help dogs receive veterinary care sooner.
Signs of Laryngeal Paralysis in Dogs
Symptoms can vary depending on the severity of the condition. Early signs may be subtle and gradually become more noticeable.
Common signs include:
- Noisy or raspy breathing, especially when inhaling
- A change in the sound of the bark
- Excessive panting
- Exercise intolerance
- Difficulty handling hot weather
- Coughing or gagging, particularly while eating or drinking
- Increased breathing difficulty during excitement or stress
- Weakness or decreased stamina
- Hind-end weakness in dogs affected by GOLPP
- Collapse or severe respiratory distress in advanced cases
A dog experiencing significant difficulty breathing, blue or gray gums or tongue, collapse, or severe distress should be considered an emergency and evaluated by a veterinarian immediately.
Why Heat Can Be Dangerous for Dogs With Laryngeal Paralysis
Dogs primarily cool themselves through panting. When the airway is narrowed, moving enough air becomes more difficult.
Warm weather, strenuous exercise, stress, and excitement can all increase a dog's respiratory effort. As breathing becomes more difficult, anxiety and overheating can further increase panting, creating a potentially dangerous cycle.
For dogs diagnosed with laryngeal paralysis, environmental management is extremely important. Exercise during cooler parts of the day, provide easy access to water and air conditioning, and avoid strenuous activity during hot or humid weather.
How Is Laryngeal Paralysis Diagnosed?
If your veterinarian suspects laryngeal paralysis, they will typically begin with a physical examination and a detailed history of your dog's symptoms.
A definitive diagnosis generally involves examining the larynx while the dog is under light sedation or anesthesia so the veterinarian can observe whether the arytenoid cartilages open appropriately during breathing.
Additional diagnostics may be recommended depending on your dog's age and symptoms, including bloodwork, chest X-rays, or evaluation for other neurologic or underlying conditions.
Treatment for Laryngeal Paralysis in Dogs
Treatment depends on the severity of the condition.
Dogs with mild symptoms may initially be managed through lifestyle changes. Maintaining a healthy body weight is particularly important because excess weight can make breathing more difficult.
Other management strategies may include limiting strenuous exercise, avoiding overheating, reducing situations that cause excessive excitement or panting, and using a harness instead of a neck collar to avoid unnecessary pressure around the throat.
Dogs with more advanced laryngeal paralysis may require surgery.
The most common procedure is a laryngeal tie-back, or unilateral arytenoid lateralization. During this surgery, one side of the larynx is permanently held in a more open position to improve airflow.
Many dogs experience a significant improvement in their ability to breathe and exercise after surgery. However, permanently opening part of the airway also increases the risk of aspiration pneumonia, so owners should discuss the benefits, risks, feeding considerations, and long-term management with their veterinary surgeon.
Supporting Dogs With GOLPP
For some dogs, laryngeal paralysis is only the first noticeable sign of a more generalized neurologic condition.
Dogs with GOLPP may gradually develop weakness, changes in gait, decreased coordination, or muscle loss, particularly in the hind limbs.
This makes whole-dog support especially important. Your veterinarian may recommend maintaining appropriate low-impact exercise, keeping your dog lean, modifying slippery surfaces around the home, using supportive harnesses when necessary, and monitoring for changes in mobility and joint comfort.
The goal is not simply to manage the airway but to help preserve your dog's comfort, mobility, and independence for as long as possible.
Can CBD Help Dogs With Laryngeal Paralysis?
CBD does not treat or reverse the physical airway obstruction caused by laryngeal paralysis, and it should never be used as a substitute for veterinary evaluation or surgical treatment when surgery is indicated.
However, some owners of senior dogs use veterinarian-formulated CBD products for dogs as part of a broader wellness plan to support areas such as comfort, mobility, and calmness.
This distinction is especially important with laryngeal paralysis. Because stress and excessive excitement can increase panting and respiratory effort, keeping affected dogs calm and comfortable can be an important part of day-to-day management. Dogs with concurrent age-related mobility concerns may also benefit from additional supportive care.
If you are considering adding CBD to your dog's routine, speak with your veterinarian and choose a product that provides transparent cannabinoid concentrations and independent third-party testing.
At VetCS, our products are veterinarian formulated, third-party tested, and created specifically with animal wellness in mind. Our team can also help owners determine an appropriate product and starting amount based on their dog's weight and individual needs.
Everyday Tips for Living With a Dog With Laryngeal Paralysis
Small changes at home can have a big impact on dogs living with Lar Par.
Keep your dog at a healthy weight, avoid strenuous activity in warm weather, use a harness rather than attaching a leash to a collar, and allow plenty of time for rest during walks. Pay attention to changes in breathing sounds, exercise tolerance, coughing, swallowing, and mobility.
Most importantly, learn what is normal for your dog. If their breathing becomes noticeably more difficult than usual, don't wait to seek veterinary care.
Helping Your Dog Stay Comfortable
A diagnosis of laryngeal paralysis can change the way you approach exercise, warm weather, travel, and everyday activities with your dog, but it doesn't mean those good days have to stop.
With veterinary guidance, thoughtful lifestyle adjustments, and careful monitoring, many dogs with laryngeal paralysis can continue enjoying walks, family time, and the activities they love.
At VetCS, we believe supporting senior dogs means looking at the whole animal. Comfort, mobility, stress management, nutrition, and quality of life all matter. If you have questions about incorporating CBD into your dog's wellness routine, our veterinary support team is always happy to help you determine which VetCS product may be the best fit.
