"I ordered two leashes and long line keepers for my dog after drooling over the products on Instagram for about a year. I couldn’t be more thrilled! The material is soft and smooth, easy to bundle up into the keeper, and easy to clean. The colors are *chef’s kiss* and we get compliments everywhere we go." - Adele F.

Excellent quality and exactly what we were looking for. Our GSD loves swimming in the creeks and rivers and this is the perfect fit when we are required to keep her on a lead while doing so. The customization options are great as well. Thanks so much!
YAY! We love to hear that! Thank you John! We wish you and your GSD many amazing adventures :)
This is my second HTH leash! I chose the sports clip to use for my larger dog who has managed to unclip a standard clip from his harness when rolling on walks. I feel much safer walking him on this. The 18” traffic handle I added has been amazing to use when passing others on walks or for other moments where I need him closer, especially given that he’s a strong dog and can pull slack out of my hands if he pulls hard enough. I’m sure this won’t be my last HTH leash!
Thank you so much Megan! So happy to hear how much you are loving your new HTH gear!
I love my dog's new sport leash! The carabiner clip is easy to use, and I can walk him without worrying if he'll snap the leash clip (cause that totally hasn't happened with other leashes...)
The traffic handle at 6ft makes it easy to keep him close if need be, but I'll never go back to less than 12 ft for his neighborhood walks. We're both so much happier. The bonus is that we've gotten noticed in the neighborhood more; I think his spiffy new leash takes all the credit 😉
Thanks so much!
Fiona! We love hearing how much you love your new HTH gear. And that you're turning more heads, too! Thank you!
It was a very nice leash. But, sadly when I left my pup tethered for a minute he somehow managed to tear/rip it into two pieces.
Hello Savannah! Please reach out to us at support@hightailhikes.com. We have a repair program that might work for you!
We are loving our 20 ft sport leash. The auto-lock carabiner is very secure and gives us extra peace of mind when we are out and about. The biothane has a great texture, it is easy to keep a grip on and tie with if needed but still super easy to clean off and never gets caught up on itself. Our dog has been dragging this thing through grass, redwood duff, sand, gravel, and more but you’d never guess it’s taken such a beating. There’s not a mark to be found on it, unlike our old flat nylon long line that is now lined with frays. And for the outdoors folks, the poppy color is a perfect blaze orange, highly visible! We will definitely be picking up more Hightail Hikes products moving forward.
Thank you Ky! We love hearing how much you are loving your HTH gear! It is amazing how durable the BioThane really is.
