Just the best!

HTH addict here! Back to review my 7th and 8th leashes from this wonderful company! 15’ is the perfect length for a sniff through the local park—enough room for some acrobatics and park trash clean up 🤣, and still short enough for super easy management. Went with two-tone leashes this time and am loving the color combos! Posting before and after muddy park photos — can guarantee they looked just like the pristine before photos after a quick rinse when we got home. Am thinking I’ll have to grab some 30 footers soon! Thanks, HTH for your contributions to my pups’s happy and healthy lives!

Absolutely LOVE seeing these pictures and your love for HTH gear! Your color combos are perfect too! Thank you Molly!

Life Changing

First off the quality is amazing. I love not having to hold onto a soggy leash after my dog had been hiking or playing ball. Second it has made my life and my dogs life so much better. The freedom we both have during hikes/adventures or just walks around the neighborhood have made an already enjoyable activity that much better.

We love hearing how much you're enjoying your new High Tail Hikes gear! Thank you Rachel!

Great product!

We love our long line! My puppy is one year old and is not yet reliable with her recall, so our 30' long line gives her the freedom to run ahead and sniff all of the things while we are out in wider spaces for hikes. I previously had a cotton long line, but when it was wet outside, the cotton line was also muddy and wet. This biothane line is easy to control even while wet and even easier to clean.

So glad you are loving your new long line! The easy to clean is my favorite feature too! Thank you Michelle! Happy tails to you!

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!
