The best accessory!

I ordered the 36 inch extender to take along on walks when I don’t want to carry my entire long leash. This thing is AWESOME! It’s smaller and lighter than I expected (can fit in your pocket), but it’s also strong enough to hold up to my puppy’s antics. It gives us an extra few feet to work with if I decide I want to let her go for a swim or explore a bit further away from me. The sport clasp is fantastic too- I’ve had other clasps fail on me, but I feel my dog is very secure on this. I can’t recommend it enough!

That is fantastic! So glad you're loving your new HTH gear and that you've found multiple ways to use it! Thank you Kelly & Poppy!

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!
