The outdoor show around MT used to have a guy that did preditor control for 5 ranches around Harlowtown give talks as part of their education talks. A couple things he said about wolves. Any canine will respond to a wounded pup. Wolves, dogs, coyotes, ect. And in his view, if electronic calling ever became legal for hunting wolves(it wasn't at that point, it is now), he would go to a friends dog kennel and record the dogs at feeding time, howling and barking. With wolves being territory animals, he felt this would be the ticket to calling in wolves.
