Which sense is responsible for the dog's sense of smell?

• A. Audition
• B. Proprioception
• C. Olfaction
• D. Pressure

Answer: (C)

Olfaction is the sense of smell, the ability to detect odor molecules through the nose. In dogs, specialized receptors in the nasal cavity pick up a wide array of scents, sending signals to the brain where odors are identified and differentiated. This system is separate from audition, which is hearing; proprioception, which is awareness of body position and movement; and tactile sensations like pressure. Dogs’ olfactory system is highly developed, with many more odor receptors and brain processing devoted to scent, which is why they excel at tracking, detection, and scent discrimination.
