Buy it!!

I was referred to High Tail Hikes from a good friend, who is also my go-to dog expert. This long line has made walks so much more fun for my dog! She loves the freedom it offers so she can run and sniff ahead of me, and I love that I still have control in our suburban neighborhood. If you’re on the fence about purchasing - do it! You won’t regret it, and your pup will love it!

Katy! Thank you so much! We enjoy hearing how much you love your new HTH Long Line! Happy Trails & Tails to you both :)

Fantastic leashes; fantastic company!

I have six of these leashes — two each of the 5’, 10’, and 7’ convertible/hands-free. They are all indispensable to my daily routines with my pups and the best leashes I have ever owned: Beautifully made, fun and vivid colors, lightweight, easy to clean, they attach securely and do not tangle because of the auto locking carabiner and swivel, and they last nearly forever with a little care. I will definitely be picking up a few longer lines in the near future. On the service side of things, orders are always executed flawlessly and communication is swift, personal, and friendly. I am always stoked to deal with this business and happy to give them all my money lol.

WOW! Thank you so much Molly! Your words mean the world to us. Thank you for sharing the pics too, we love seeing HTH in the wild!

Our favorite long lines!

I bought two 15-ft leashes (1/2in: one was green apple/teal and the other was flamingo/goldenrod) and LOVE them! They get dirty every day with the dogs and are easy to clean and look brand new. They are very lightweight and I’m happy I upgraded to the locking carabiner. I have already referred several people to the site and will absolutely purchase from HTH again in the future!

High Quality Stuff

These are really some great long lines, and the color options are so fun. The medium (1/2" width) work awesome for my 1 year old Border Collie mix. Strong but also light weight and easily packable. I definitely will be buying more!!

Thank you Lindsey! So glad you (and your Border Collie mix) are enjoying your new Leash! Happy Adventures to you both :)

Amazing long lead

Just received our 20ft sport biothane leash and we love it!
Gives the dog so much more freedom on her walks and I love it because it can go thru anything without becoming smelly or dirty and is super easy to handle as well. Love the colorful choices!
In the pictures Brier is enjoying her new found freedom all the way on the East coast of Canada

Kerstin! We are so glad you and Brier are enjoying your new long line! Happy Adventures to you both and THANK YOU!
