What functional purpose do the Bloodhound's long, low-set ears serve while tracking?
Answer
They act like a funnel, sweeping scent particles toward the nose.
When the dog lowers its head to follow a trail, the lengthy ears sweep the ground, effectively trapping scent particles and directing them precisely into the nasal passages.
