Brachycephalic breeds are those which have short noses, such as Pugs, Boston Terriers, Bulldogs, Shih Tzus and Boxers. This shortened face shape can resut in the syndrome known as brachycephalic airway syndrome (BOAS). BOAS may be charaterized by narrowing of the nostrils, a small windpipe, and excessive soft tissue structures at the back of the throat (the soft palate and laryngeal saccules).
Symptoms of the syndrome vary but can include, loud and rapid breathing, snoring, exercise intolerance, retching and collapse.
For minimally affected pups, a regular exercise routine, healthy diet and avoiding overheating will help with breathing and ease other symptoms. Early surgical intervention to widen narrow nostrils will also reduce the risk of deterioration of the airways that can lead to severe BOAS. In more severe cases surgical removal of excessive soft tissue in the back of the throat can also be performed to inprove breathing ability.
Both Rocco the Pug and Angel the English Bull Dog are patients that have recently undergone airway surgery to improve their breathing at the Veterinary Centre Oamaru. We are happy to report that both are doing well, are more active and snoring less.
