Dog-proof Your Cables




So our puppy, recently teething, decided to chew her way through much of our furniture, and more dangerously, electrical cables (!)

This is just a quick instructable to suggest one easy way to armour up your cables, using shower hoses :-)

Caveat: You should be comfortable with rewiring electricals to proceed here. This is NOT an instructable on how to deal with household voltage AC devices.

Step 1: Cut and Measure

Based on the length of your cables (and reach to the nearest socket), find/buy one of those metal shower hoses. This one cost me about USD6.

Step 2: Cut and Push Cables Through Hose

Once you are comfortable with the length of the cable you intend to work with, cut the cable and push it through the hose. If you have any silicone based spray lube, now's the time to use some as there will be much friction as you push the cable through. I used some shapeloc plastic to fashion threaded couplings at the ends, so that the existing hose sleeve can be screwed in. You can also choose to use silicone, or epoxy.

Step 3:

This is a simple hack, but it does assume that you already know how to rewire your electricals, and is able to work with shapeloc/epoxy already. I just thought I should post it as it took me a while to realise, after hunting high and low for for tough cable sheaths, that the answer was found in the common bathroom :-)

    I wiped my cables with a rag soaked in olive oil and chilli powder as a deterrent. That worked too!

    This is a great idea, I will most likely do this when we move.

    Great idea. But seeing as our dog chewed through an aluminum conduit, this may not work for us. LOL

    Why cut the cable? why not simply open up the plug and remove the wires, then push the cable through.

    Oh. That's because there was a push switch in the middle I wanted to get rid of. If your wire length fits the hose length, just disconnect from the plug and push right through :-)


    Oh man, this is great! I wish I knew about this idea when my dog was a puppy, she was terrible with wires! Thanks for the share!
