Training devices for domestic animals that do not operate by constricting around the animal's neck are disclosed. These devices have collars or harnesses that maintain their size, with a means for actuating a member or members that protrude inwardly toward the neck of the animal. Actuation of the device by tension from a leash attachment provides a pinching action between the protruding members such that the skin of the neck is pinched to provide a training cue to the animal without choking the animal.
