Made in the USA Biothane Long Line Dog Leashes
Durable • Waterproof • Proudly American Made Dog Gear

Looking for the ultimate training and recall leash? Our Biothane Long Line Dog Leashes are proudly handmade in the USA and built for performance, safety, and longevity. Available in 10 ft, 15 ft, 25 ft, and 33 ft lengths, with four width options (3/8", 1/2", 5/8", and 3/4"), these long leads are trusted by trainers, hunters, and everyday pet owners who demand more from their gear.

Why Choose Biothane Over Traditional Nylon or Leather?

• 100% Waterproof – Biothane is a high-quality coated webbing that performs like leather in strength and flexibility, but unlike leather or nylon, it will never absorb water. Mud, dirt, and muck rinse right off, keeping your leash clean and odor-free.

• Hygienic & Bacteria Resistant – No lingering dog smells or mold buildup, even after heavy outdoor use.

• Extreme Durability – With up to 750 lbs of breaking strength, Biothane leads are built for the most demanding working dogs.

• All-Weather Reliability – Stays flexible in extreme cold and won’t melt or get sticky in extreme heat.

• Trusted Material – Used by national sports leagues, international military, and space organizations where safety, strength, and cleanability are critical.

Solid Brass Hardware: Built for Saltwater

Every leash is finished with solid brass hardware, making it ideal for coastal environments, boating, and saltwater use. Unlike stainless steel or plated metal, brass naturally resists corrosion and pitting. That’s why brass has long been the standard in marine and boating equipment—it forms a protective oxide layer that prevents rust even in harsh saltwater conditions. Your leash’s clip will hold strong, no matter how many times your dog splashes through the surf.

Perfect for Training & Recall

Long line leashes are an essential tool for:

• Recall Training – Practice safe off-leash recall in open spaces.

• Obedience Training – Give your dog freedom while maintaining control.

• Hiking & Outdoor Adventures – Allow exploration without losing connection.

• Tracking & Nosework – Perfect for search training, scent detection, or hunting dogs.

• Safe Exercise – Great for parks, fields, or the beach where dogs can roam but stay secure.

⚠️ Not for Tie-Out Use – Long line leashes are designed for training and supervised activity only. They are not chew-proof and should never be used as a tie-out.

Handmade in the USA – American Made Proud

Each Biothane Long Line is crafted by hand in the USA with meticulous stitching and attention to detail. We use wax-coated thread for added strength and resilience, ensuring your leash will last through years of training sessions, adventures, and daily use.
