Greatest leashes I've ever experienced. I was reluctant to switch to biothane, because the leashes looked so thin and dainty. I always used nylon leashes until I was convinced by a professional dog trainer that this was the way to go. After researching, I discovered K9 Ops and their leashes. Phenomenally well made, great looking, comfortable to use, and Super durable!! Utilizing components far above what other manufacturers use. Best part is, the customer service is second to none! They are a small company, not without issues, but they are honest, upfront, and friendly. If I ever need another leash (which I probably never will, their one mistake) I'll be back! Thanks again!
love it
By far the best in the game! The last leash you’ll need to get! Customer service is unmatched!

Built by Handlers, For HandlersInspired by Moki
K9-OPS began when product designer Christian Denney teamed up with police K9 handler Cole Peterson to solve a simple problem: finding training gear tough enough for Cole’s K9 partner, Moki.
Built from real-world experience, K9-OPS creates durable, high-performance gear for working dogs, high-drive breeds, and the handlers who demand more from every training session.
Every product is designed with purpose, tested in demanding conditions, and built to deliver the strength, reliability, and performance serious dogs, like Moki, require.
Every product we make starts with one question:
Would this pass the Moki test?
Unfortunately Moki passed away in April of 2024. His legacy and inspiration will continue to be honored daily within our business, in our family, and by his fans.
