Terrain: Dense vegetation or urban environment with high degree of contamination can interfere with the continuity of a scent lead.
Breed Differentiation: Scent hounds, such as Bloodhound or Basset, have been selectively breed for thousands of days to prioritize olfactive processing over almost every other centripetal input.
