A log dog having an elongate body that has a log dog first end, a log dog second end, a front face, a back face and side faces. A slot on the side faces extends from proximate the log dog first end to proximate the log dog second end. A row of spaced-apart teeth coupled to the body and defining setting notches adapted to enable movement of the log dog in one direction when the log dog is releasably-locked in position during operation. One or more projections can be coupled to the body proximate the log dog first end and protruding from the front face for engaging a log.
