Laryngeal paralysis is a disorder that affects the larynx (voice box) in dogs. It occurs when the nerve that controls the larynx muscles is damaged or not functioning correctly, resulting in difficulty breathing, especially when a dog is excited or exerting itself. This can be a serious and potentially life-threatening condition, so it is crucial to understand the signs, treatments, and prognosis of laryngeal paralysis in dogs. 

Symptoms

Symptoms of laryngeal paralysis include loud or labored breathing, particularly when a dog is exercising or in a warm environment. You may notice your dog coughing, gagging, or choking, and its gums may have a bluish tinge caused by a lack of oxygen. Bluish gums are a sign of hypoxia, a condition in which the body is not receiving enough oxygen. In severe cases, a hypoxic dog can collapse or even lose consciousness. 

Causes

In dogs, laryngeal paralysis can be congenital (present at birth) or acquired (developing later in life). Congenital laryngeal paralysis is a rare inherited disorder, while acquired laryngeal paralysis is more common and occurs due to various causes, including neurological diseases or injury. In addition, certain dog breeds, such as Labrador retrievers, are prone to developing laryngeal paralysis later in their lives.

Treatment Options

The treatment options for laryngeal paralysis depend on the severity of the condition and the individual dog. Medications, such as anti-anxiety drugs and bronchodilators, can help to manage symptoms, but surgery is often the most effective treatment. 

Surgery for laryngeal paralysis is called a laryngeal tieback, which involves suturing the affected vocal fold to the side of the larynx and the arytenoid cartilage. This procedure opens the airway and allows the dog to breathe more easily.

Prognosis

The prognosis for dogs with laryngeal paralysis varies depending on the severity of the condition, the dog's age, and their overall health, 

Dogs with surgery to correct the problem generally have a good prognosis, with most dogs returning to normal or near-normal activity levels. However, surgery can be risky, and the condition may recur after surgery. Dogs with severe or advanced laryngeal paralysis may have a guarded to poor prognosis and require lifelong management.

What to Do if You Think Your Dog May Have Laryngeal Paralysis

It's important to note that early diagnosis and treatment are crucial for the best outcome for dogs with laryngeal paralysis. If you suspect your dog may have this condition, it is essential to consult a veterinarian as soon as possible. Your vet can diagnose the condition through examination and may recommend further testing, such as an X-ray or CT scan, to confirm the diagnosis and recommend the best treatment.
