The BEST biothane leashes! The quality is unbeatable and the team is so great to work with. Me and my 80 pound German Shepherd have had the best time exploring with our new leash!!
Thank you so much, Kiera! 💛 “Buy the leash!!” — we couldn’t ask for a better recommendation! 😄 We’re thrilled that you and your German Shepherd are loving your new leash and getting out there to explore together.
Hearing that you appreciate both the quality of our gear and the experience of working with our team means so much to us. Thank you for trusting High Tail Hikes with your adventures, and here’s to many more miles, sniffs, and explorations ahead! 🐾✨
When purchasing my first 50ft long line I saw the option for a long line keeper and figured at the least it would be helpful for storing the line, however after working with the line a bit I found so much use for the line keeper other than storage. From securing the line when I had it wrapped around my waist to keeping the extra length picked up, it has been a godsend. Not to mention the color description was perfect and I was able to find the same exact color of biothane for the line keeper as my service dog’s main working harness, leash, and collar.
Thank you so much, Elyot! We’re thrilled to hear the long line keeper has been such a game changer for you — it’s amazing how versatile that little piece can be! We love that it’s helping with everything from storage to managing extra length on the go.
And matching your service dog’s full setup? That’s next-level — we’re so glad the color was spot on! (Thanks for sharing pics too!) Wishing you and your SD many smooth, organized, and stylish adventures ahead. ✨
