Dovahzul cacnon words only reference bad smells and scent - pook (stink) and bein (foul). To convey scent, I recommend using "ok/ek rii ko su/ven" (his/her essence in the air/wind) since scent is associated with the air that carries it. Here's a sample English sentence with all of those words used, followed by a possible Dovahzul equivalent:

"The scent of the hunter was hidden to the wolves. He smelled them before they sensed his presence."

"Fin rii do ah lost vonun wah fin grohiikke. Rok mindok rii do niin ko fin su us nust siiv ok kos." (Literally, "The essence of the hunter was hidden to the wolves. He knew the essence of them in the air before they found his presence.")
