Details
They can smell odors with more clarity and range, even to the point of distinguishing subjects by their scents; they can track subjects and distinguish between simultaneously-occurring smells (as well as being able to take notice of when someone has masked their natural scent); however, they may also be involuntarily sensitive to loud smells, aromatic attacks and nasal-based allergens.
