Although dogs are capable of following both visual and olfactory cues, it appears that scent is their most effective source of information. Equipped with enhanced physical and neurological olfactory structures, a dogs sense of smell is much more advanced compared to that of humans. Specialized turbinate bones in the canine nasal cavity allows for increased exposure of chemical receptor cells to the air. This, paired with a proportionally large segment of brain devoted to olfaction processing, results in the enhanced smelling ability of canines.
