Made from galvanized, braided steel, our leashes make it impossible for dogs, including teething puppies, to chew through. They also come with a comfortable handle constructed from extremely strong, high-quality webbing with a breaking strength of 3,000 lbs. We’ve stress tested these leashes for up to 900 lbs. and field tested them over the past eight years. We use swivel base snaphooks to attach to the collar to allow your pet to move freely without getting tangled. The Walk-N-Lock tie-up feature allows you to safely secure your dog to a post or a tree.
