Which species does the term 'canine' refer to?

The term 'canine' specifically refers to dogs and their relatives within the family Canidae. This family includes not only domestic dogs but also wolves, foxes, and other similar animals. The term is derived from the Latin word "canis," which means dog. In a veterinary context, understanding this classification is important for recognizing species-specific health concerns, behaviors, and breeding practices.

In contrast, the other choices pertain to different animal families. Cats belong to the Felidae family and are referred to as felines. Horses are part of the Equidae family and do not relate to the term canine in any way. Lastly, rabbits fall within the Leporidae family and are classified as lagomorphs. Each of these terms signifies a distinct group of animals with unique characteristics, which is crucial for those studying veterinary science to grasp clearly.
