Veterinary Technician National Exam (VTNE) Practice Exam

The English bulldog is classified as brachycephalic because it has a short, flat skull structure, which results in a broad and rounded head. This characteristic is typical of brachycephalic breeds, which often exhibit a variety of potential health issues related to their facial structure, such as respiratory problems and difficulties regulating body temperature. Brachycephalic dogs generally possess a shorter muzzle and looser skin around the face, contributing to their distinct appearance.

In contrast, the other breeds mentioned do not have the brachycephalic trait. Golden retrievers have a more elongated muzzle, giving them a longer facial structure typical of mesocephalic breeds. Greyhounds are known for their aerodynamic shapes with long snouts, which again places them outside the brachycephalic category. Great Danes, while large dogs, also possess a long muzzle and are classified as a different head type known as mesocephalic. Therefore, the English bulldog is the clear example of a brachycephalic breed among the options provided.
