Best leash!

This is truly the best leash I’ve ever used. It’s comfortable to hold and does not get knotted. The brass clasp and fittings are great quality. And the best part is that I can wipe everything down after a good ol’ dirty walk!

Thank you so much, Fran! We’re thrilled to hear this is the best leash you’ve ever used. We designed our gear to be comfy in your hand, durable with quality hardware, and easy to clean after those muddy adventures — so it’s wonderful to know it’s working perfectly for you. Happy walks ahead!

Best leashes!

These biothane leashes are the best out there. Full customizable, the colors are vivid, and sooooo easy to clean. I'm particularly fond of the brass hardware for beach outings. I also love how you can choose any length. I have leashes 8ft, 10ft, 15ft, and 20ft from here. The longer two are drag lines and the shorter ones are my go-to lengths for walks. Being able to add just a few feet to the standard 6ft leashes you can buy in store really helps reduce pulling and gives my dogs that extra little bit of freedom to reach all the smelly sniffy spots. They're incredibly lightweight but strong and I love not worrying about what they'll get dragged through since they can be washed easily without staying wet.

Thank you so much for your honest review Alyssa, we sure do appreciate you!!!
