Laryngeal paralysis in dogs is a condition that cannot be cured, but can be treated and managed. Our Citrus Heights vets explain how you can give your pup the best quality of life possible while living with laryngeal paralysis.
Laryngeal Paralysis
Just like humans, a dog's larynx (commonly referred to as the voice box) is composed of a series of plates of cartilage that form a box in the throat. The most important function of the larynx is that it closes off the trachea (windpipe) and lungs when eating and drinking. Alternatively, It will open wider if a deep breath is needed.
The integrity and stability of the larynx are maintained by the laryngeal muscles. When the nerves of these muscles become weak (paretic) or paralyzed, the muscles relax, and the cartilage plates tend to collapse inwards resulting in laryngeal paralysis.
What causes it?
Laryngeal paralysis is the most common disease that can affect the larynx of a dog. Although the cause of laryngeal paralysis is unknown in most cases, there are cases in which the reasons are known. Below are some of the known causes:
- Trauma to the throat
- Tumors or lesions in the neck or chest
- Congenital disease
- Old age
- Cushing's disease
- Hyperthyroidism
Most impacted by LP are dogs that are middle-aged or older, as well as medium to large-sized breeds. This, however, does not mean smaller and/or younger dogs can't develop it as well.
What are the symptoms?
Symptoms of laryngeal paralysis can vary. Unfortunately, because the initial signs of this disease are not very intimidating, ranging from mild shortage of breath, coughing, to loud breathing, many cases go undetected and untreated.
Here is a list of some of the symptoms you can expect to see in a dog suffering from laryngeal paralysis:
- An increase in panting during stress or on hot/humid days
- Increase in susceptibility to heat stroke
- Lethargy
- Noisy panting
- Anxiety
- Voice change
- Collapsing
- Dark red, purple, or blue gums
- Coughing or gagging when eating or drinking
- Respiratory distress
Can it be treated without surgery?
More mild cases (especially in smaller breeds) of laryngeal paralysis can be controlled with medications such as anti-inflammatory drugs, antibiotics, and sedatives.
Avoiding hot environments and strenuous exercise with your pup, while also avoiding collars that put pressure on your dog’s neck will increase the success of these mild cases. Harnesses are recommended for diagnosed dogs.
If the case is more severe, your dog may need to have surgery.
Treatment for Laryngeal Paralysis Via Surgery
Severe cases of LP will require surgery. Several different techniques have been developed due to the frequency of their appearances. Discuss with your vet to determine the best course of action for your dog's circumstances.
The most common technique is called unilateral arytenoid lateralization (UAL). Also referred to as laryngeal tie-back surgery, this method uses two permanent sutures to tie the collapsed cartilage to the side of the larynx, keeping it open and air to pass through easier.
Although the surgery will not completely restore laryngeal function, it will significantly improve your dog's quality of life, giving them an additional one to three years of life on average.
What to Expect After Surgery
Coughing or gagging is initially normal following surgery while eating or drinking, but tends to clear up over time. The owner should be aware of the symptoms of food/water aspiration, which is the most common complication after this surgery.
Please monitor your dog closely for vomiting, gagging, or regurgitation. Your dog should also be monitored for hind leg weakness, and if noticed, notify a vet immediately.
