The Tether Tug XL is our biggest, strongest, most durable Tether Tug. Built with our strongest, thickest core, as well as a larger, more heavy duty in-ground base, the Tether Tug XL is designed for all dogs over 60 lbs and any size pit bull. The XL's knotted rope toy is set higher than the original Tether Tug, but still provides the same level of energetic play as the original. The XL comes with an in-ground base that allows the tug to spin and turn, as well as a quick connector to allow for toy changes. Recommended for dogs over 60 lbs.
