OldieLaryngeal paralysis is a common acquired problem of middle-aged and older large breeds, above all the Labrador Retriever, and also the Irish Setter and Great Dane1. The muscles that open the airway during breathing stop working, so the dog breathes through a narrowed opening. Research at Michigan State University showed that in most dogs this is part of a slowly progressive nerve disease that also affects swallowing and, later, the back legs, which is why it is now often called geriatric onset laryngeal paralysis polyneuropathy2.
The early signs are a change in the bark, noisy or raspy breathing, a dry cough, gagging when eating, and tiring easily; they progress over months to years1. Heat and excitement make it worse. A senior Labrador that suddenly cannot get its breath on a hot walk, with blue gums and panic, is an emergency: cool the dog and go straight to the clinic.
Diagnosis is by examining the larynx under light anaesthesia. Mild cases are managed by keeping the dog cool, calm and lean, using a harness, and avoiding exertion in heat; more severe cases are treated with surgery that opens one side of the airway1.
This is general information, not a diagnosis. Your vet knows your dog.
