Does your dog jump over your existing fence with ease? The Standard Dog Proofer Fence Extension Kit utilizes our straight fence height extensions to make your fence up to 3' taller and stop dogs from jumping over existing fencing!
Extend the height of an existing fence of nearly any type. Our dog-proof fence top works with several fence types, including but not limited to wood, chainlink, brick/concrete block, and decorative aluminum/wrought iron.
Need an extension that can raise the fence height taller than three feet tokeep your dog safe and secure? We can help! Please contact us.
The Dog Proofer Standard Fence Extensions are made of a single piece of 1 ⅜” diameter, 16 gauge galvanized steel tubing that is finished in a durable black powder coating. Each fence height extension has two mounting plates welded in place that work on any flat fence post, wall, or surface. Using U-bolts, the extensions can also attach to round or square fence posts, making them ideal extenders of chain link fencing and decorative aluminum or wrought iron fences.
See the "Kit Contents" Tab for information on what is included in each kit size.
Each dog-proof fence topper kit includes your choice of mesh fencing material. Choose either Durable Poly Mesh or Heavy-Duty Welded Wire Mesh.
Durable Poly Mesh is a fencing material made with a specially formulated thermoplastic polymer formed into a grid that is not only flexible, but also very strong. This fence height extension material has a 600lb breaking strength and includes UV inhibitors that make it perfectly suited for outdoors. Poly mesh tends to be easier to install and less costly compared to the welded wire option.
If your dog is aggressive or tends to chew or pull at the fence with their teeth, we offer an upgraded Heavy-Duty Welded Wire Mesh fence extension option. This is a strong steel fence material that guards against chewing damage. The fence material is made of steel strands formed into a square grid pattern and welded together to create openings that measure 1.7” x 1.7”. The diameter of the individual wires is about 2.0-2.2mm. The welds are made with ungalvanized steel, and the whole mesh sheet is hot-dip galvanized before the black vinyl coating is applied. This makes for very strong welds and durable, long-lasting fence height extension material.
Our Freestanding DIY Dog Fence can be used to build a new fence line from the ground up and create a standalone enclosure for your dog. But did you know it can work with your existing fence, too? Create a barrier across a walkway, use it as a partition to divide a yard or keep dogs separated, or use part of your existing fence to create an enclosure within your yard. Freestanding DIY Dog Fence can even be used alongside a dog-proof fence topper!
Gaps in your fence line? Incomplete perimeter fence? Or maybe a shared fence with your neighbor that you can’t modify? Fill in the gaps with our Freestanding DIY Dog Fence!
Dog going over AND under the fence? Consider combining Dog Proofer’s fence height extension with our Dig Proofer system.
