Houdini-Proof Dog-Proofer Fence Extension Arm


The Existing Fence Dog Containment Arms (ARM ONLY) when coupled with a welded wire or strong poly fence will secure your 4' or higher fence against jumping and climbing dogs. The arms can attach to most walls and fence types including but not limited to wood, chain link, wire-backed split rail, decorative aluminum/wrought iron, and PVC. The arms are made of 1 3/8" diameter 16 gauge galvanized steel tube and are finished with a UV stable black powder coat finish. 

Works on nearly all fence types:

The arms secure to wood posts with screws or lags, round metal posts (like for chain link) with U-Bolts, and square metal posts with Square U-Bolts.

Both fence options are secured to the Dog-Proofer arms with our black UV stable 120lb test Heavy Duty Zip Ties.

Happy dog Happy owners!

The Houdini proof fence extender has allowed my dog free access to the yard again. We don’t have to worry about her jumping into the neighbors’ yards anymore.
It was easy to install as well!

Charlie Cooke
Great fence

The Installation was easy and took me a few hours to complete the install with the help of my 9 and 11 year old daughters. I have a Gsp that was climbing my 6’ fence and jumping it. I extended our fence to 7’ and she was still jumping it. I installed the Houdini fence with the poly fence and extended it to 8’! She hasn’t managed to get our of the yard again which is a blessing. That’s for the help ans the great product.

Effective low cost alternative that is easy to install

Perfect solution when we needed a fast way to increase the height and security of our cinderblock fence to accommodate a fence jumping rescue dog!

Make your fence safe

We added the extension arms to our dog daycare outdoor yard fence. It's the perfect solution, quality product and highly recommend it to anyone trying to secure their fence.

Works great, easy to set up but definitely not a one-person job.

Piece of Mind

The curved arm system has provided me piece of mind that my dog will not escape. Customer service is the best! Hired a handyman and the two of us put it up along 200 ft of fencing in a day. Highly recommend this if you have an escape artist.

No more scaling the gate

Dogs used to bounce off the wooden fence and gate to go over the slightly lower gate. The extension arm and mesh wire ended that!
