Biothane 5/8ft x 20ft Working Dog Leash - Blue Aqua - Odor-Proof

In this review of the Biothane 5/8' x 20ft Working Dog Leash the bottom line is simple: this is a practical long line built for tracking, field training and working dogs that need a waterproof, easy-to-clean lead. The reviewer found the leash especially well suited to scent work and open-area training because the 20ft length and lightweight construction let a handler give distance without excess drag. Its standout feature is the coated Biothane webbing that stays flexible after wet or cold exposure, making it a reliable option for handlers who work in muck, snow or heat.

Key Features

• Waterproof coating: The leash emerges from swampy or wet conditions dry and free of lingering odors, which reduces cleaning time after training sessions.
• Super heavy webbing: A flexible webbing core bonded with a waterproof coating offers higher durability than leather in demanding outdoor environments.
• Solid brass hardware: The brass snap resists rust and provides a durable attachment point for working dogs in search and tracking tasks.
• Temperature stable: The material remains flexible in extreme cold and does not soften in extreme heat, keeping handling predictable across seasons.
• Long 20ft length: The extended length is well suited to tracking, Schutzhund drills, and search training where distance control is required.
• Made in the USA: Constructed from high quality materials with consistent build quality and color options for team or identification needs.

Who It's For

The leash is aimed at handlers of medium and large dogs who need a long, easy-to-clean line for training, tracking, search work or dog sport. It works well for scent training where a full 20ft of slack lets a dog follow odors while remaining connected and controlled by the handler.

It is not intended as a chew-proof tether or a permanent tie-out; owners who need a chew-resistant or permanent outdoor tie should look for hardware and materials specifically rated for those purposes. Puppy owners should supervise use since the product is not chew-proof.
