Is your dog digging under your fence? This Dig Proofer system is a simple and extremely effective solution to prevent digging and possible escapes. Works with any fence type whether you have wood, metal, chain link, PVC, brick, block, or others. The Dig Proofer uses heavy gauge black powder-coated galvanized welded wire to create a physical barrier on the ground leading up to your fence. The bottom is staked into the ground using included specially designed heavy galvanized metal stakes. The top is held in place with your choice of staples, screws, zip ties, or your choice of the fastener (fasteners not included due to the wide variety of fencing materials, though they can be purchased separately.) The Dig Proofer XL version features 42 inches of height so that you can now install coverage up to 24-30 inches on the ground and still allow for 12 inches of coverage vertically up the fence. The welded wire squares are 1.75" x 1.75" so your dog cannot scratch, chew, or fit through it, but so that grass can easily grow through it. The welded wire can also be trimmed to accommodate certain heights or to work around obstructions in the fence line.
