So what in the world does “vestibular” mean?
“Vestibular” refers to the vestibular system—a complex network of structures located in the dog’s inner ear and connections to the central nervous system. The vestibular system perceives the body’s orientation with respect to the earth’s gravitational field and facilitates normal movement. The brain, eyes, and body use the information gathered by the vestibular apparatus to maintain proper posture and balance.
