1000+ FIVE STAR REVIEWS

This collar, like everything else we have from HTH, is sturdy, easy to clean, and looks absolutely beautiful on my pup. We’ve worn it hiking, dock diving, and for our everyday trips out and about, and it has held up wonderfully. Another great piece of gear from an awesome brand!

– ERIN L.

This is my third leash from High Tale Hikes and I have nothing but good things to say! The quality is amazing, the biothane is great for people with dexterity issues, and the customization aspect is unmatched...I love this small business and can’t wait to add a custom collar to match the leash that has become a permanent part of our everyday lives!

– PAYTON S.

Every detail of these leashes are complete perfection. They are lightweight yet strong and durable. Easy to clean. Easy to store. Colorful. Convenient. I feel safe using this product on my high energy, 82 pound ball of fire! Just such great leashes. Can’t say enough good things about them!
