Which sense helps a dog maintain balance and stand upright without falling?

• A. Vision
• B. Equilibrium
• C. Hearing
• D. Olfaction

Answer: (B)

Equilibrium is the sense of balance and spatial orientation, managed by the vestibular system in the inner ear. It detects head movements and gravity, sending signals to the brain to adjust posture so a dog can stay upright and not fall. Vision can help provide environmental cues, and proprioception contributes to awareness of limb position, but the primary mechanism for maintaining balance is the equilibrium/vestibular system. Hearing and olfaction don’t provide information about head position or balance.
