Abstract: A dog tug apparatus includes a housing having a dispensing portion and a tug device configured to extend from and retract back into the housing. The tug device includes a tug having teeth scrubbing bristles extending there from. A resistance assembly resists unwinding of the tug line, and includes first and second opposing electromagnets suspended about the periphery of a slotted metal disk. A controller can adjust the resistance applied by the resistance assembly and provide an audible signal at the end of an exercise event. A recovery mechanism provides a means for rewinding the tug line about the spool after the tug line has been unwound, such as during a dog exercise event. In use, the rotation of the spool in the direction to unwind the tug line rotates a reduction gear system and results in the rotation of a treat dispensing mechanism to dispense a dog treat.
