Laryngeal Paralysis (LP)
Laryngeal paralysis occurs when one or both sides of the larynx do not open and close properly. This condition can impede the dog’s ability to get oxygen. It can also lead to overheating since dogs pant to cool themselves down, however, a dog with LP cannot pant effectively. In severe cases, the dog can develop cyanosis (a blue color to the gums) from lack of oxygen. He may collapse and even die from this condition.
LP can happen to any breed, but is most commonly seen in older large breeds.
The first sign of LP is a change to the sound of the dog’s bark and a rough sound in the breathing.
