This 1.8m long anti-digging bar is perfect off you have a dog that enjoys digging. You know how frustrating it can be especially if they use that "love of digging" to dig out of their kennel or fence. Short of pouring cement in your back yard, there hasn't been much one could do to prevent this problem; but no more! Use this 1.8m long anti-digging bar on the interior panels of the K9 Kennel. They attach directly to the kennel itself and act as a simple "stopper." Dogs can't chew or claw through these bars and they certainly can't fit through them.
