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.
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.

Houdini-Proof Dog-Proofer Fence Extension Arm
I have nothing but praise for all the people at Dog-Proofer, especially Jen Kapla, the"Customer Experience Guru". Over the span of three months she patiently went over my three separate orders and unique installation issues with me as I constructed a barrier for my Houdini dog. Each order was processed, shipped right away and arrived on time with all items very well packaged. I have ordered many things from companies that leave much to be desired but Dog-Proofer stands out as one of the best and the good folks who work there make it so.
Works like a charm. Very nice !!
We had an escape artist. This fence keeps him in looks a little like jail but from road you can barely tell. More importantly our dog is safe! Thank you.
Our dog is a whiz at escaping (she's the only dog to ever escape from our local dog daycare). Ever since we put this fence up - no escapes! It was easy to install, too!
My Yorkie was able to get thru the bars on my new fencing. This solved the problem. Easy to install and practically invisible from a short distance.
The fence went up smoothly, all the parts were here, and it is working beautifully.
I bought this for my sons yard, he has an ecape artist little pug/boxer at getting out of the yard. This fence cured that problem. Plus the yard is not getting dug up anymore. This product is great. Well worth it.
Our volunteers just installed the dog proofer fencing and it has been a game changer for two of our high flight risk dogs. Bruno the red coon Hound could easily climb our 8ft metal fence, and Diamond our boxer could hop over the same fence with ease, both escaping to our horror( captured safely). Since the install neither of them have been able to escape, allowing them to run free and safe within the confines of our yard. Thank you so much!
We have German Wirehair Pointers and they can’t jump or climb this fence. Before putting this up a 6 foot fence was nothing for them to get over.
Works great to keep pups in!! At first we installed it a little too high, had corners opened and the pups were trying to climb through. We lowered it and feel more comfortable about keeping the pups in. Would definitely recommend!
We have a very agile dog who was jumping the fence regularly to play with the neighbor’s dog. We installed this and our problem is solved. Now our dog watches the other dog longingly from our side of the fence.
The gate is exactly what we hoped for- sturdy and easy to operate.
Well made, easy to install, even on a round post and rail fence like mine. All you need are a couple clamps, some screws and washers and a string to run between posts to keep the posts at whatever level you want them. Be sure to buy the zip tie puller and cutter or you will spend a lot of extra time and effort. This was actually a fun project that did exactly what the manufacturer claimed, and it was far less expensive than what a new fence would have cost me, assuming you can find anyone who will show up and actually build it. The extension fence is barely noticeable, but when you do see it, it looks pretty darn nice. The dogs can't get out, other animals won't come in.
