"They put a scent lurer "” like urine from a coyote in her heat cycle or another smell that makes the animal want to grasp the M44 head "” and any coyotes, wolves, are attracted to it.

It also affects humans, so after watching his dog die, Canyon had to rush to the ER to make sure he was not harmed.
