Love how easy this is to take along

I got the 36” extender. It’s so small and fits right in my pocket and it’s easy to pop on when needed. We use this much more than the 10 ft line. I highly recommend it! I will order a slightly longer one soon!

Love it!

Love this extender to give our dog a little more length on walks in the woods with the HTH hands-free leash that we have.

So glad you are loving your leash extender! We appreciate you!
