The vibrating "rumble" capability has been replaced with a far more practical "doggy poop bag" function. Though this leash is completely functional paracord may not be suitable as a leash for larger dogs.

Step 1: Materials + controller breakdown
I used a broken XBOX controller for my dog leash. There were 7 screws on the underside holding the controller together, with one hiding under sticker.
When all screws are removed the controller can be easily pried apart.
Step 2: Remove vibration motors
This controller had 2 vibration motors. These were removed to make space for the dog waste bags, they also made the controller much lighter.
These motors were plugged into the controller board and were easily unplugged. I saved these motors for use on a future project.
Step 3: Size waste bag area
To fit the dog waste bags inside the controller some of the internals would need to be removed.
I found these dog waste bags at my local pet store. They usually come in small rolls and are inexpensive.
Step 4: Cut controller board
The bags almost fit inside the controller, but the controller board would need to be modified to accommodate the bags. Using a rotary tool with a cutting wheel a portion of the controller board was removed.
