How to tell if your leash needs repairs

Make it a point to look over your leash once a week, checking to see if it's time to make any repairs. The older the product, the more likely it will be to need a helping hand.

If the leash has extensive damage from overuse or from being repeatedly dropped on the ground, this is a signal that it's time to replace the entire thing with a new leash. Before you throw the old leash away, however, consider saving it so you can harvest flexi leash replacement parts in the future. This can save you a lot of time and money with dog leash repair.

Step 2: Test the tension

Test the tension and retraction by pulling out the entire length of leash and allowing it to retract. This will allow you to see which parts of the leash might need replacement.

Step 3: Inspect the leash

Undo the Allen screws on the side of the retractable leash. Carefully use a standard screwdriver to gently pry the top part away from the bottom. Try to pry evenly on each side to avoid breaking the plastic casing.

Visually inspect the various leash parts for signs of damage, such as burns, cuts, rubs, tangles, and frayed or worn sections. Check all sewn areas for loose, missing, or damaged stitches. Then, replace the leash material if necessary. Most leashes are made of nylon or leather.

Step 4: Check the spring

Check that the spring is functioning correctly. When it's working properly, the tension in the spring will increase as you pull the leash out from the coil. If there is not enough tension to allow the leash to retract, replace the spring.

Step 5: Clean the leash

Use compressed air to clean the inside of the leash, blowing out any particles of dust or dirt.

Step 6: Replace the cover

Replace the plastic cover and secure it with the Allen screws. Pull out the entire length of leash and retract it a few times after replacing the parts to ensure smooth operation.

Once you've completed all of the steps, you're finished with your dog leash repair, and your leash should be good to go.
