How to Stop a Dog From Crawling Under a Fence


An "L" shaped fence blockade made from welded wire and fastened to your existing fence and the ground keeps dogs from digging a Houdini escape route from your yard.

Things You'll Need

  • Leather gloves
  • Sturdy shoes or boots
  • Tape measure
  • 2-by-3-inch welded wire fencing, 4-feet tall
  • Wire cutters
  • Automotive zip ties
  • Landscaping staples
  • Fencing staples (optional)
  • Rubber mallet (optional)
  • Decorative rocks (optional)
  • Grass seed (optional)

Step 1

Put on leather gloves and sturdy shoes or boots. Cut about a 3-foot section of 2-by-3-inch welded wire fencing from the roll with wire cutters.

Step 2

Measure 2 feet up your fence from the ground level with a tape measure. Place one end of the 4-foot tall fencing on the 2-foot mark from the ground.

Step 3

Insert an automotive zip tie through both the welded wire and through a chain-link fence. Insert the pointed end of the zip tie through the square end and pull the pointed end through to tighten the tie. Continue placing zip ties about 6 inches apart down the fence to connect the top of the welded wire section.


  • If you have a wooden fence, attach the top of the welded wire to your fence with fencing staples and pound them in with a hammer.

Step 4

Smooth the welded wire from the top attachment area downward against the fence with your gloved hands. Press the extra 2 feet of wire at the bottom flat against the ground with your hands. It will form an "L" shape with a 90-degree angle where the fence and ground meet.

Step 5

Walk down the fence placing a foot on the 90-degree angle, pressing down the flat area on the ground.

Step 6

Insert landscaping staples in the welded wire on the edge farthest from the fence. Space the staples about every 6 inches apart down the fence section.


  • Use a rubber mallet to install the landscaping staples if your ground is very hard or has rocks in the area.

Step 7

Cut and install additional sections of welded wire to line the entire inside of your fence.

Finishing Touches

You can leave the dog barrier as is or add other decorative items to the bottom.

  • Place large decorative rocks on the horizontal section of fencing to hide it.
  • Plant grass seed over the wire for it to fill in and match your lawn seamlessly if you have soil under the horizontal fencing from previous digging activity.
  • Allow the existing grass under the horizontal fencing to grow through it and hide it.


  • If you have a large breed dog, attach the welded wire every 3 inches on the fence and the ground.
