Laryngeal paralysis is a genetic disorder that is most common in large dog breeds. The condition prevents the larynx from properly opening to allow air into the trachea. As a result, the airway narrows and breathing becomes extremely difficult.

List of affected breeds:

Genetic research has linked this gene and condition in the following breeds:

Alaskan Husky

Two dogs are looking up at the sky with their mouths open. The dog on the left is brown and white, and the dog on the right is brown with white markings on its chest and paws. Both dogs are wearing harnesses and are standing in a grassy field with a blue sky in the background.

What does this mean for a dog with this trait?

There is no cure for laryngeal paralysis. Anti-anxiety medications may help, as can limiting exercise and exposure to heat. Aspiration pneumonia can be treated with antibiotics. In extreme cases, surgery may be used to open the larynx.

Symptoms

Signs of laryngeal paralysis include difficult breathing, like raspy breaths, coughing, and excess panting. Dogs may experience exercise and heat intolerance. When breathing becomes too difficult, a dog’s tongue and gums may turn blue and they may collapse. Aspiration pneumonia may occur as a secondary infection.
