Handcrafted in our studio in New York, our dog leashes are hand-spliced to withstand hundreds of pounds of pull with the ends then "whipped" (an old nautical term) for additional durability. Fixed on the ends are our solid brass lockable carabiners designed to allow additional safety for our rescue pups big and small. Nothing ages more beautifully than marine-grade rope and hardware. The individually-numbered, stamped tags on each FOUND leash remind us of the uniqueness of our pets, and allow us to keep track of the number of animals we have helped so far.
