Frequently Asked Questions
Our leashes are handcrafted from BioThane®, a waterproof and stink proof coated webbing made in the US. BioThane is incredibly strong while still being lightweight, doesn’t absorb water, odors, or dirt, and is a cinch to clean, making it an ideal material for dog gear.

BioThane® is exceptionally strong for its weight, with a minimum 1,000 lb break strength per inch of width. An intact BioThane leash paired with quality hardware will hold up to even the strongest pullers. That said, BioThane (like any leash material) is not chew‑proof - it’s engineered for tensile force, not teeth. Please don’t leave any dog unattended while wearing a leash. If chewing happens, reach out - we may be able to repair or offer a discounted replacement.
We offer five core leash styles - pick based on your lifestyle and activities:
- Quick Ship Leash - Our classic loop‑handle leash. Ships in 2–5 business days with free returns.
- Custom Leash (Bestseller) - Fully customizable (length, width, colors, hardware, add‑ons). Ships in 3 - 10 business days.
- Simple Hands Free Leash (Customer Favorite) - Lightweight and streamlined, with a convertible handle for hands free use and custom add-ons available. Ships in 3-10 business days.
- Multiway Hands Free + Convertible Leash (Original Bestseller) - Our most versatile design; wear/use 8+ ways (standard, hands free around the waist or crossbody, multiple length options, and more), custom add-on options available. Ships in 3 - 10 business days.
- Drag Line - A leash with no handle for a lightweight “off‑leash” feel. Low‑profile design is less likely to snag; optional D‑ring at the end lets you clip a traffic handle when needed. Ships in 3 - 10 business days.
Quick tip: Not sure where to start? Our Custom Leash and Simple Hands‑Free Leash are the most popular everyday picks.
Leash Width: Choose based on your dog size and preferred leash feel:
- 3/8" - Small dogs (under 30 lb). Light in hand yet strong.
- 1/2" - Small-medium (up to 60 lb) or anyone who prefers a lighter feel.
- 3/4" - Medium-large (60+ lb), strong pullers, or for a more “traditional” leash hand feel.
Leash Length (activity guidance):
- 4 ft : Short car-to-trail transfers or ultra close quarters.
- 6 ft : Standard leash length.
- 8, 10, or 12 ft : Our most popular everyday lengths; give your dog freedom while keeping them safe.
- 15 ft - Perfect for hiking, decompression walks, and recall practice.
- 20 ft - Great for beach trips, camping, and travel - extra room to roam while staying safe.
- 30 ft - Sniffaris, big open fields, SniffSpots, and backyards. Not advised for beginners.
New to long lines? Start with something just a few feet longer than your current leash (e.g., 6 ft → 10 ft), then increase length as you and your dog get comfortable.

To clean your leash, soak in warm soapy water, gently clean with a towel or sponge, rinse and dry. Always rinse your leash and hardware with fresh water after a beach trip. Store your gear dry and in an area out of the sun (to reduce UV damage) with good ventilation.
To keep your brass clip working well, periodically clean and then add a few drops of penetrating oil such as WD-40 into the clasp/spring mechanism and open and close multiple times to help clear gunk.
Brass hardware will not rust but may develop a patina over time (can be cleaned/polished); black hardware will show cosmetic wear over time and/or rust if stored wet.

We love our 6 ft sky blue leash with grape accents 🩵💜 perfect for going to dog training classes or dog friendly public outings where a shorter leash is needed!
Thank you so much, Andrea! We’re so glad you’re loving your Sky Blue + Grape combo — such a dreamy pairing! It sounds perfect for training classes and outings where you need a little more control. Wishing you and your pup many stylish, happy adventures ahead! ✨
I was first introduced to the concept of “long-line” leashes when attending puppy training at the SPCA in Dublin, CA. I will absolutely never go back to the standard 6’ leash! The Biothane material is also such a game changer. Love this product and would definitely purchase again. Thank you, High Tail Hikes!
Thank you so much! We love hearing that discovering long-line leashes was such a game changer for you — and we agree, it’s hard to go back once you experience that freedom. We’re so glad the BioThane material has been working well for you, too. Thank you for your kind words and support, and we hope you and your adorable pup enjoy many more happy walks ahead!

Love all of them. Wish I would have put the handle higher up than the standard. But that’s on me!
Thank you so much, Lorraine! We’re so glad to hear you’re loving the quality of your gear. Wishing you many happy walks ahead!
My mom lets me get into all of my favorite things with this leash! She lets me dig and throw mud on it, roll around in funky smells and take long walks in the rain because she can wipe it down and it’s like new again!
Thank you so much! We love this review — sounds like your mom is letting you live your best, messy life! 😂 We’re so glad the leash is holding up to all that digging, mud, and rainy-day fun. That easy wipe-down is exactly why we love BioThane too. Here’s to many more adventures (and funky smells!) ahead!
we have two custom leashes - one at 10 feet, which is our everyday walking leash and one at 6 feet, which is our “mission” length (when we’re on a mission and need to stay close) and we love both! our cairn terrier loves to roll around in grass, dirt, all the things, so having a leash that is sturdy and easy to clean is definitely a life improvement.
I could not love this more! Easy to clean is definitely important when they love to roll around! Thank you Jennifer :)
I love this leash so much I immediately ordered another. Easy to hold onto, beautiful colors, perfect for hiking and neighborhood walks. I love that I can make it a crossbody leash if needed. A+
Thank you Sara! We are so glad you are loving your new HTH gear so much that you needed another!!! We wish you many amazing adventures!
Huge fan of the product, so much that I have several different custom leashes from here. I highly recommend adding the Custom Traffic loop for longer lines. Quality is solid and colors are great!
Great tip! Thank you so much Chloe!
We ordered a leash and are so happy with it! The material is perfect for outdoor use and super easy to clean. We were looking for a specific color and emailed their customer support and they were able to help us out! I am so excited we were able to get the exact leash we were looking fro!
So happy we could help, thank you Amanda! (thank you for sharing photos, too cute!)
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!
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!
I never understood the use of the long time until I finally tried one. My dog has become more leash reactive as she gets older. The 15ft long line give us safety and security at the park. The material is very easy to clean. The texture helps with grip. We are still getting the hang of wrangling the leash and keeping it from getting tangled. I went with the 1/2 inch for a 65 lb pit mix. She does not pull so it works well for us. We also have a 6ft 3/4 inch with a traffic handle for neighborhood walks. We will be back for more in the future!
Your pit mix is beautiful! Thanks for sharing the cute video. So glad you are loving your new long line. A little more practice and you'll be a pro (it does take a little getting used to) Thanks Lauren!
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!
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!
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!)
This is exactly what I wanted! The color is beautiful and the product is made well and with high quality materials. I already want an even longer line for hiking.
We are so glad we could make your long line dreams come true Calgary! Thank you!
Walks with my dog are so much more enjoyable and dog-directed! My dog seems so much happier on walks. Thank you!!!
Fiona, Thank you!! So glad you are both happier on your walks with High Tail Hikes!
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 you have no idea how much your kind words mean to use, thank you for such a great review!
I am a biothane and longer leash convert! These leashes are lightweight, strong, supple and easy to clean. I bought 8 foot for our neighbor and local park walks and 10 foot for hiking and more open area walks. I used to walk with 6 foot leashes and noticed adding just a couple more feet has made such a difference for both myself and my dogs. Less pulling for me and my dogs can move at a pace that's more comfortable for them and have more time to sniff around.
Love that you are a 'convert' Maria :)Thank you!
