How to Make a DIY Dog Leash with Heat Shrink Tubing

Heat shrink has a ton of different uses. Aside from its traditional function for wire and cable management, it’s also a great tool for many easy DIY home and lifestyle projects. It’s a strong and long-lasting material, making it a low-cost and effective solution for a variety of different uses. This super simple dog leash is just one great example of the many ways you can use heat shrink in your daily life, and to create something special for you and your furry friend.

For this project, you’ll need some rope, heat shrink tubing, a heating method to seal, and a carabiner or swivel snap hooks.

Once you’ve compiled your materials, you’re ready to get started.

1. Cut the Rope

Start out this simple DIY project by cutting your rope to a desired length. Measure out how long you want your leash to be, and then add around 1.5 feet for the clasp and 2-3 feet for the handle (depending on how large you want the loop to be).

We recommend using a strong polypropylene rope for a long-lasting leash that won’t tear with some tugging from your pup. Once you cut your rope, you can secure the ends and prevent fraying with either a bit of heat shrink, or you can burn the edges if you use polypropylene rope.

2. Tie a Knot

For the next step, you will need to create a poacher's knot for the clasp side of your leash. This video is an easy step-by-step demonstration on how to tie this knot securely to ensure your clasp will not slip off. If you choose to use a swivel snap hook for your clasp, make sure to loop the rope through the clasp before tie the knot to secure it to your leash. Another option is to use a carabiner, which you can hook on after you’ve tied your knot.

3. Cut Heat Shrink

To secure the knot you’ve tied, cut two pieces of heat shrink, about 3 inches in length, and thread them onto the rope from the untied side. Once both sides are knotted, you’ll then use these pieces to secure the rope in place, but for now just make sure both pieces of tubing are on the rope before creating the handle.

4. Secure the Heat Shrink

Now you can slide one of the pieces of heat shrink tubing around the rope you’ve tied into a poachers knot. Make sure the heat shrink is covering the loose ends of the knot, and then using a heat source melt your heat shrink around the rope to secure your clasp portion of the leash. To heat the tubing, you can use everything from a standard butane lighter to a heat gun.

5. Create the Handle

With the untied side of the rope, create a loop for your wrist with your desired size. You can check through different sizings by securing the rope temporarily with some tape until you’ve created a loop size you’re happy with.

6. Secure the Handle

Then, once you’ve measured your desired handle size, slide one of the heat shrink pieces up to the handle, and make sure it covers both ends of the loop. To make this easier, you can secure the handle with electrical tape and then melt the heat shrink on top of this tape. Using your heat source, melt the heat shrink around the rope to secure the handle. Once the heat shrink is fully secured, you’re done!

In just a few simple steps and with the help of heat shrink tubing you’ve made your very own dog leash! These leashes are perfect because you can customize them to any length and size, for any sized dog. Heat shrink ensures that your leash will last a long time and provide enough strength to sustain a little wear and tear from your pup.
