Introducing our latest product, the Biothane Long Line - a waterproof long dog lead designed to provide maximum freedom and safety for your furry friend. Made from durable and waterproof Biothane strapping, this long line can withstand even the toughest outdoor conditions while keeping your dog under your control.


Your dog will have plenty of room to explore and have fun on all your adventures. The tangle-resistant design of this long line ensures that it is easy to pack and store.


Whether you're hiking, walking in the park, or playing in the backyard, our Biothane Long Line is the perfect solution for keeping your dog safe and secure while they explore and have fun.


We make our long lines in 3 sizes


1/2" 13mm for dogs under 10kg (shih tzu, Jack Russell, Chihuahua, Dachshund, etc.)

5/8" 16mm for dogs under 15kg (Poodle, Cocker Spaniel, French Bulldog, etc. )

3/4" 19mm for dogs 15kg+ (Australian Cattle Dog, Border Collie, Labrador, Rottweiler, working dogs, etc.) (best seller)

Our long lines feature strong strapping with a breaking strength of 220-340kg, but the wider straps may be challenging for smaller dogs to maneuver on wet terrain.
