20ft HunterOrange Biothane Dog Leash 5/8 in - Waterproof Long Line

In this review of the 20ft HunterOrange Biothane leash, the bottom line is simple: this is a practical long line for training and working dogs that need a durable, easy-to-clean lead. It is aimed at handlers who perform tracking, scent work, search and rescue or Schutzhund style training and want a waterproof, flexible line that stands up to weather without trapping odors. The single biggest reason to buy is the combination of a long 20ft length and a waterproof Biothane coating that dries quickly and stays flexible in extremes.

Key Features

• Waterproof coating: The coated webbing repels muck and dries quickly so the lead remains odor-proof and practical after wet fieldwork.
• Super Heavy webbing: A bonded core and heavy webbing deliver higher durability than leather for demanding outdoor use.
• Temperature resilient: The material stays flexible in extreme cold and resists softening in high heat, keeping handling consistent.
• Solid brass hardware: The brass snap resists rust and is suited to law enforcement, search and rescue or dog sport environments.
• Long 20ft length: Provides distance for tracking and scent training while maintaining control over medium and large dogs.
• Made in the USA: Manufactured from quality materials with consistent construction and available color options.

Who It's For

This leash is best for handlers running scent training, tracking drills, search and rescue practice, or working dogs in open areas who need a long, weatherproof line. It works well for medium and large puppies through adult dogs when a 20ft line gives the required stand-off distance.

It is not meant as a chew proof tether or for unattended tie-out; users seeking a chew resistant or permanent restraint should choose a different product. Casual owners who only walk their dog around town may find shorter, lighter leads more convenient.
