⭐⭐⭐⭐⭐ "I have tried quite a few long lines at this point, and these are by far my favorite. They are lightweight, easy to clean, and still fairly grippy in the PNW drizzle. I do wear gloves if it's really wet. I walk two dogs at once and these leashes do NOT tangle. Ultimately, the excellent customer service, the endless customization, and high quality mean I've found the only leashes I'll buy from now on." - Mary A.

First Biothane Leashes - LOVE!

This is my first biothane leash purchase and I’m so glad I found High Tail Hikes! I ordered a 6’ leash for daily walks in town and a 4’ leash for training classes. The quality is great and I love the customization and color options! I already can’t wait to order a convertible leash and a long line!

We are so glad to hear you are enjoying your new HTH gear! Thank you Jacklyn!! It does become an addiction, no worries, we are here for it!

thank you for the long lead life!

we absolutely love that our dogs have more distance to safely sniff and explore. the material of the leash feels sturdy, lightweight, and has a smooth feel to them. we take them everywhere, so are very glad they’re easy to clean!

Leslie Ann! Oh my goodness, your little love is absolutely adorable! Thank you for sharing with us and for your honest feedback, We appreciate you!

Best Long Line

I’ve owned several biothane long lines over the years, and our new long line from High Tail Hikes is my favorite! My dog and I both enjoy the freedom of the 30ft long line. The 1/2” width is perfect for my 45lb dog. I loved the idea of a traffic handle on the long line, and asked if they could place a custom handle 6ft from the snap. High Tail Hikes was so easy to work with on the custom handle and Cory replied to my emails quickly. The craftsmanship on the line is wonderful, the brass hardware is durable, and it’s a genuine biothane product. HTH is owned by a positive reinforcement/ force-free trainer, which matches with my training ethics and makes me want to support them even more! I can’t wait for our next piece of High Tail Hikes gear.

JESS!! Thank you so much! We love hearing how much you love your new HTH gear!! Can't wait to serve you again!

Light weight and so strong

This leash was exactly what I was looking for. The perfect length (10 ft), with adjustable handles. It was even stronger than I expected, though. My girl puts hers through it all (mud, trees, high prey drive pulling). I honestly don't think I will buy another brand ever again. I'd only be disappointed.

Wow, thank you Cassandra! So happy to hear you are loving your new gear so much!

1 year in, we’d buy again

We LOVE our 20 foot long lines. We’ve had them for about a year now and these things are durable. The only thing I wish I’d thought about before buying was that our harnesses had black rings for clipping leashes, and I got brass fixtures (wish I’d gotten the black carabiner) - to be clear, that’s totally my fault. Regardless, we use these leashes most days of the week. We pair our 2 dogs long lines with a sport handle with a rotating carabiner so the leashes can function as 2 independent leashes, or as a 2-dog, less-tangly setup (because of the rotating carabiner). The only issue I have is that I want to buy another set of leashes for my dogs because these ones are so cute and great, but I know I don’t need another leash because these are going to last forever.

What a great testimonial after a year of use! So glad you are loving the long lines functionality! Thank you Kim! (just so you know, its ok to want more BioThane long lines, we totally understand!)
