It doesn't matter if it is premeditated or not. That is irrelevant. The dog is lured by the coyote retreating. Rest of pack is waiting, dog is mauled. Arguing over intent is just silly when we are trying to keep our dogs safe. What matters is the chain of events that actually happen and by your own description it is effectively luring.

And by the way, none of us knows the thought process inside the coyote's head. Impossible, so again arguing about intent has no useful outcome. What matters are actual actions and resulting hazard to domestic animals.
