Which term describes the bottom of the back feet in animals?

The term "plantar" specifically refers to the surface of the back feet in animals, particularly in relation to standing and walking. In this context, the plantar surface is the part that makes contact with the ground.

In veterinary terminology, the palmar surface pertains to the bottom of the front feet, which would not apply to the back feet. The term dorsal refers to the top side or the surface facing the sky when an animal is in a natural position, while ventral describes the underside or belly side of the animal. Since the question focuses on the underside of the back feet, "plantar" is the correct term to describe that specific area.
