Perfect width, length and clasp size

I’ve been looking for a longer leash for Peaty, our 12lb Chiweenie. This fit the bill! I ordered the light green (sage?) and it’s beautiful, BUT I dark is a better choice! So dirty and despite cleaning, I’ve stained it. Doesn’t affect anything so no big deal! Peaty is the black dog, meeting a shelter friend.

Thank you so much, Valerie! 💛 We’re so glad you found the right width, length, and clasp size for little Peaty! It sounds like the leash is getting plenty of real-world use—which is exactly what we love to hear. 🐾

We also appreciate your honest feedback about the lighter color and staining. That’s helpful for us and for other customers considering their color choice! And we love that Peaty got to put the leash to use meeting a shelter friend. Looks like they had a great time. 🥰 Wishing you both many more happy walks and adventures together! ✨

Love this product

This is my 6th leash from High Tail Hikes. I love these leashes. They are light weight, well made, easy to clean and stay looking like new. They get dragged through mud, brambles, dirt, freshly mowed grass and still look great. They are perfect for sniff walks and exploring.

Thank you so much, Deborah! 💛 Your sixth leash—wow! We can’t tell you how much your continued support means to us. 🐾

We love knowing your leashes are getting properly put through their paces—mud, brambles, dirt, grass, and plenty of sniffy adventures—and still cleaning up beautifully! That’s exactly what we want our gear to do: let dogs explore without their humans worrying about the mess. 😄

Thank you for trusting High Tail Hikes again and again. Here’s to many more muddy, sniff-filled adventures with your pups!

Great product

I love High Tail Hikes leashes. I love the color selection and options to customize each leash. They are great for walks in the woods, rainy days and mud season. They are light weight and easy to clean. They don’t tangle as much as other leashes. They are a must have.

Thank you so much, Deborah! We absolutely love your photo — your pups look ready for adventure! We’re so glad you’re enjoying the colors, customization, and easy-clean features of your leashes. They really are made for muddy trails, rainy walks, and all the in-between moments. We’re so happy to have you and your pups as part of the High Tail Hikes family!

Great custom leash

I needed a long line without a handle and this is a great leash. The biothane material meant cleaning it was a breeze, even though it was dragged through a creek.

Glad to hear we could meet your needs Kat! We wish you many happy adventures, thank you!!

More relaxed walks!

I purchased two 10 ft leads for our neighborhood walks. The leashes are very well made and we found the transition from traditional leashes to long lines fairly seamless. The videos helped!

I love the versatility of being able to easily give my pups more freedom! They can now explore and even get some zoomies on walks! I’ve even noticed decreased reactivity! Yay for sniffing!

That is so awesome! We love hearing that Brittany, thank you!!

Getting one in each length!

I've ordered 4ft, 6ft, 10ft, and 20ft leashes so far and they've all been great. I chose HTH leashes because of the customization options. The longer leashes have a traffic handle for better control near the pup and each leash has scissor clips because they're just easier to deal with. Not to mention the dual colors are just outstanding and always seem to complement each other. I've also tried all the handle options and they all have their uses. The only downside is that I've got a bite-y puppy and he's already chewed through a leash in the 3 min we weren't looking. So def watch out for that. Biothane is pretty easy to chew through -_-

First, total cuteness overload! THANK YOU Irene! We wish you both many adventures together!

Great leashes for the smaller pooches

I wanted a biothane leash for my small dog. All the ones that I found had giant hardware, which was too heavy for my miniature schnauzer. I was able to get a custom length, width, and color with small hardware, which was perfect for her. It was really well made we use ours multiple times a day and they hold up and can be cleaned easily. Even though it was custom-made, it still arrived fairly quickly.

We are honored to help make your 'small' leash dreams come true! Thank you Cara, cheers to many happy adventures! Thank you for sharing pics too!

Adventure leash

This leash is a nice, light weight for my 18 lb. pup. I was worried it would hang heavy on his collar, but it seems just right.

Happy to hear that! Thank you Laura!

Loving our new leash

I have always love biothane leash because of its ease to clean and all the colors. I tried a longer length this time with the gorgeous sage color (my current fav). I like it. It gives my pup a bit more freedom and she seems to like it too.

Thank you Jennifer! We wish you (both) many happy trails!

Light weight long line

Thank you Kim!

I went back to buy another

I have two of these in the 6 ft length with brass scissor snaps. One has the D ring at the base of the handle and I find it very useful for carrying used waste bags. I also have a 12 ft sport convertible leash that I love. I’d like to see a purple that’s between violet and lavender, more of a royal purple. Also, the brass hardware doesnt match all the silver-covered metal on my dog’s harnesses but that’s just personal pickiness. It didn’t keep me from ordering two lol

I love the purples too! Thank you for your review Rachel! So glad you're loving both of your HTH long lines!

Love!!

It was time for a new long line after a few years of constant use. I like the 20 foot length to use for swimming at the lake and trails at my neighbors. My German Shepherd's love the extra length and room to explore and sniff. The leashes are lightweight and easy to hold when walking two dogs. And easy to clean off the sand and dirt. I plan on getting 8 foot ones for in town and parks when it warms up in the spring.

My favorite is the ease of cleaning too! Thank you Whitney for your love of HTH gear! Happy Tails to you and your GS!

I love that these leashes

I love that these leashes are lightweight, supple, resist knots and tangles and are easy to clean. I usually use a 6 foot leash but decided to go up to 8 feet for local walks and 10 feet for hiking. My little gal is not much of a puller, but now with longer leashes she pulls even less. She also gets more room for sniffing and exploring. I even tried the 10 foot on my 70 pound dog and it's so strong I think I'll be getting him a 15 foot in 3/8 inch for hiking as it will be more lightweight than the 1/2 inch

We are so happy to hear you are loving your new longer lines! Happy Trails, Thank you Maria!

Easy to clean and see under street lights at night

Bought a neon orange 3/8width leash for my lil' 11lb mutt. I love that it's highly visible, strong, and able to clean easily. Only wish would be to have option to get stainless steel spring clips. Otherwise I just purchased the last leash we'll ever need.

Perfect leashes

I am so happy that I decided to order these 2 leashes. They are the perfect width and very light for my 8 and 14 pound dogs. They seem very strong with great hardware and the best part is they are easy to clean. The customized 8 ft. Length gives them some extra space to sniff and the Color’s are really nice. I’m going to be ordering a 15 ft long line soon.

10 Stars, Fantastic Product with Great Service!

I recently ordered two 25' long lines for my dogs. I am in Canada, and ordered them despite the currency exchange and international shipping time because there is nothing comparable available here. They are beautifully made, easy to handle and unlike many biothane products they feel supple and great in your hands,. They are light and strong, the colours are gorgeous and they clean up with a wipe. The hardware is the higesth quality. I am absolutely delighted with them and recommend High Tail Hikes products to all my friends and clients.

Lucy Gives New Leash a Thumbs Up!

Our newest rescue puppy gives her new leash a thumbs up! Our trainer recommended your product to us and we love it. Lucy came from a hoarding background and everything is new and exciting for her. We bought the 20 ft. Length and it gives her space to run and explore. So much to see, so little time! I am glad we found out about your products.

Thank you so much, Cynthia! 💛 We love hearing that sweet Lucy is enjoying her new adventures! 🐾 It’s wonderful that her 20 ft leash is giving her the freedom to explore and discover the world at her own pace. Thank you for giving Lucy a loving home and for trusting High Tail Hikes to be part of her journey! Wishing you both many happy sniffaris ahead! ✨

I just entered and now I’again. It was a good review. 100 character limit? I just wasted 10 min.

Maybe the title was limited to 100 characters. That was not made clear up front.

I don’t have more time.

It was a glowing review but I’m writing it twice.

Thank you so much, Thomas! 💛 We’re so sorry about the frustration with submitting your review — especially after you had already taken the time to write such a thoughtful one. We completely understand how aggravating it is to have to start over when the character limit wasn’t clear.

The fact that you still left us 5 stars and let us know your original review was a glowing one means more than you know! Thank you for your patience, your time, and most of all, your support of High Tail Hikes. 🐾

Super light weight and cute!

I got these leashes for my pups and absolutely love them! Compared to others we’ve purchased on Amazon, these feel much more durable while still being incredibly lightweight. The colors are also beautiful and feel much more elevated. They’re so light that my dogs barely seem to notice they have a leash on. Definitely a great find!

Thank you so much, Stephanie! 💛 We love hearing that you noticed the difference in both the durability and lightweight feel of your leashes. Gear that’s strong without feeling bulky is exactly what we’re going for—especially when it means your pups can explore comfortably!

And we’re so glad you’re loving the colors too. ✨ Thank you for choosing High Tail Hikes and for taking the time to share such a wonderful review. Wishing you and your pups many colorful adventures ahead! 🐾
