Things You'll Need
- Discarded nylon climbing rope
- Carabiner(s)
- Utility knife or scissors
- Lighter
Instructions
Measure out a 7 to 8 foot piece of rope and cut it off the main line.
Hold the cut ends at the lighter flame to melt the nylon fibers. This prevents fraying.
Tie a small double-figure eight knot at one end of the rope (see "Resources"). Slip the carabiner --- the metal D-clip with a hinged gate --- into the knot's loop.
Tie a double figure-eight knot at the opposite end where the loop is big enough for your hand to use as a handle for the leash.
Clip the carabiner onto the dog's collar loops.
