Which animal is classified as "porcine"?

The classification of "porcine" specifically refers to pigs. This term comes from the Latin word "porcus," which means pig or hog. In veterinary terminology, animals are often grouped based on physical characteristics, biological classification, or common usage. Pigs are members of the family Suidae and are recognized for their distinct traits, including their behavior, physiology, and importance in agriculture.

The other choices—dogs, cats, and horses—are classified under different terms. Dogs belong to the canine family, cats are part of the feline family, and horses are referred to as equine. Understanding these classifications allows for better communication and education in veterinary medicine and animal husbandry, as each group has unique needs, care requirements, and health considerations.
