Brachycephalic, also known as pug- or short-faced, and is the term used for dogs with short muzzles such as the Shih Tzu, Boston Terrier, Pug, Pekingese, Bulldog, and Boxer. These breeds have problems with collapsed tracheas, heatstroke, and a congenital problem known as elongated soft palate.

The soft palate is a flap of tissue located at the upper back part of the throat and is normally positioned to act as a flap to prevent food or liquid from entering the air passage. In brachycephalic breeds, the upper jaw is recessed which results in the soft palate being located on the epiglottis rather than just touching it which can cause problems for the dog when eating, breathing, or swallowing.

Because this condition is common in brachycephalic dogs, vets will regularly check these breeds for elongated soft palates. This condition is normally not life threatening, but can be stressful for the dog during exercise. Signs of snoring, wheezing, snorting, and coughing when the dog is running are signs to watch out for. As the soft palate becomes more swollen and irritated, breathing may become problematic during relaxed periods or when sleeping. As this irritation increases the muscles and ligaments controlling the larynx begin to stretch and can result in the larynx collapsing and obstructing airway which can be life threatening.

An elongated soft palate does not always become a serious condition and can be corrected with a surgical procedure that removes the excess tissue on the palate.
