A dog’s front teeth are pointed and intended to penetrate rather than chew through materials. However, although it is extremely difficult, a dog might find a way to get their mouth far enough into the fence grid and use their rear teeth to gnaw through the fence. Thus, it is a possibility that your dog could chew through your fence enclosure. As a preventative measure, we here at Best Friend Fence have developed a black PVC-coated, welded galvanized wire barrier to be used in conjunction with your enclosure system. Available in various heights, this Chew Guard is designed to be attached to the bottom (approx. 1’-2’) part of the fence enclosure and flared inward. The Chew Guard should then be staked onto the ground to prevent digging.
