Here at C3 LLC, dogs are some of our favorite people . . .

Shortly after they adopted Vela, their beloved Italian Greyhound, Kassie and Jay, the owners of C3 LLC, started making custom dog leashes from the ultra-durable American made cordage that goes into every C3 Device. They came to realize it was a great way to repurpose the high-quality cordage pieces that were too short to be integrated in C3 Devices. They also found that cordage that had a previous life as a C3 Device could be laundered and repurposed in C3-4K9 leashes.

In the interest of reducing waste and bringing joy to dogs and their humans, the innovative C3-4K9 dog leash was born. Durable, comfortable, and modular, the C3 4K9 "forever leash" lets you focus on bonding with your best friend, not when you’ll need your next leash.
