If you were to try one lure for coyotes, this would be a good one, because even “shy” coyotes will respond, hungry or not. For all types of sets, and will work year-round. One of John’s all-time favorites on canines, and has helped him catch a lot of big tom bobcats over the years. John’s favorite use – a good smear on a well blended flat set made a short distance away from main sets at a location. (Leave them alone and let them pick up the shy ones).
