Do I have to use the tethers?Updated a year ago

YES! The are actually quite important in maintaining correct tension on the line while it is moving by allowing flexibility and a little give for those times when your dog is racing over the line, stepping on it, tugging at the lure, and making those fantastic lunges and rolls as they attempt to capture the flag!

If you have worn out your tethers, you can always use a loop of the line to tether the drive and pulleys to the stakes.

 Benefit of using line - you can make the tether the exact length you need it to be.
