Which breed is most likely to suffer from proptosis due to orbital structure?

• A. Hound breeds
• B. Working breeds
• C. Brachycephalic breeds
• D. Sporting breeds

Answer: (C)

Proptosis, which refers to the abnormal protrusion of the eyeball, is particularly common in brachycephalic breeds due to their unique skull structure. Brachycephalic breeds, such as Bulldogs, Pugs, and Boxers, have short and flattened skulls that lead to shallow eye sockets. This anatomical arrangement increases the risk of the eyeball being displaced, especially in the event of trauma or excessive pressure on the eye. The conformational features of these breeds can result in reduced orbital space, making the eyes more prone to injury and displacement. Such structural predispositions mean that brachycephalic dogs are significantly more vulnerable to developing proptosis compared with other breeds. In contrast, breeds classified as hounds, working breeds, and sporting breeds generally possess longer snouts and more pronounced orbits, which provide better protection and support for the eyes, thereby reducing the likelihood of proptosis. Understanding this anatomical difference is crucial for veterinary professionals when assessing the risks associated with different dog breeds regarding ocular health.
