Waterproof BioThane® Long Line Dog Lead with Handle

Each long line is individually handcrafted in our New Zealand workshop using genuine BioThane® and premium solid brass hardware.

BioThane® is a strong polyester webbing with a durable, flexible coating, making it ideally suited to dog leads designed for active, everyday use.

All hardware is solid brass, with three finish options:

Gold – natural solid brass
Silver – nickel-plated solid brass
Matte Black – PVD-coated solid brass

Every long line is cut, assembled and finished by hand to your chosen length, width, colour and hardware combination.

The best lead length depends on both your dog's size and your own height.

3ft (90cm) – A shorter lead for close control. Often suits larger or taller dogs, strong pullers, heel work and busy areas.

4ft (120cm) – A versatile everyday length that suits many dogs and handlers.

5ft (150cm) – Offers a little more freedom and is particularly useful for smaller or short-legged dogs, or taller handlers.

6ft (180cm) – Extra length for relaxed walks, loose-lead walking or dogs that benefit from more freedom.

Tip: Taller handlers and shorter dogs will generally be more comfortable with a longer lead, while a shorter lead provides more close control.

See the Dog Lead Length Guide in the image gallery for a visual comparison.

Long Lines

For training and exploring, our long lines are available in 3m, 5m, 7.5m, 10m and 15m lengths.

3m – A manageable step up from a standard walking lead, providing extra freedom while keeping your dog relatively close.

5m – A versatile choice for recall training and everyday exploring, with a good balance of freedom and manageability.

7.5m – A useful middle ground when you want more room to explore without the additional bulk of a 10m or 15m line.

10m – Provides plenty of freedom for recall training, sniffing and exploring larger open spaces.

15m – Best suited to situations where maximum range is useful, such as recall training, tracking and large open spaces. The additional length also means more lead to manage and carry.

When choosing a long line, consider both the amount of freedom you want to give your dog and how much line you are comfortable handling. Longer lines also become heavier, particularly in wider BioThane®.

LEAD WIDTH

Choose from two BioThane® widths depending on your dog's size and how you plan to use your long line.

½" (12mm): Lightweight and less bulky, making it a good choice for smaller dogs or when you want a lighter long line. The difference becomes particularly noticeable with longer lengths, where there is less material to carry.

Approx. BioThane® webbing break strength: 225kg

¾" (19mm): A wider, more substantial option suited to medium and larger dogs, or for owners who prefer a little more BioThane® in the hand.

Approx. BioThane® webbing break strength: 340kg

Break-strength figures refer to the BioThane® webbing itself and are not a rated working load for the completed lead.

LEAD LENGTH

Choose from 3m, 5m, 7.5m, 10m or 15m. Longer lengths give your dog greater freedom to explore but also mean more lead to handle and carry. See our Dog Lead Length Guide for help choosing the right length.

COLOUR

Choose your main lead colour and handle colour to create your own combination. Keep it classic with a single colour throughout, or choose a contrasting handle for a more individual look.

HARDWARE FINISH

All of our hardware options are solid brass. Choose from:

Gold – natural solid brass

Silver – nickel-plated solid brass

Matte Black – PVD-coated solid brass

OPTIONAL ADD-ONS

Floating O-Ring – Add a floating O-ring to the handle to create a handy attachment point for the trigger hook when your long line is coiled for storage.

Personalised Nameplate – Add a hand-stamped solid brass or stainless steel nameplate with your chosen contact details.

Both optional extras are available separately and can be added to your order using the add-ons below the Add to Cart button.

BioThane® is waterproof and very easy to care for. Simply wipe clean with a damp cloth or rinse under fresh water after muddy, sandy or salty adventures. For a deeper clean, use warm water with a little mild soap, then rinse thoroughly.

Allow your long line to air dry before storing.

Gold solid brass hardware will naturally develop a patina over time and can be polished if you prefer a brighter finish. Silver nickel-plated and Matte Black PVD-coated solid brass require no polishing; simply rinse and wipe clean.

After use in salt water, we recommend rinsing the entire lead and hardware thoroughly with fresh water.

As with all dog leads, regularly check the BioThane®, hardware and attachment points for signs of wear or damage before use.

Our BioThane® Long Lines are designed for supervised walking and training, including recall work, exploring open spaces, tracking and giving your dog greater freedom while remaining connected.

Long lines should always be used under supervision and are not designed for tethering or leaving a dog tied up unattended.

For safety, avoid allowing your dog to run at full speed to the end of the line, and take care to prevent the lead from becoming wrapped around people, dogs or other obstacles during use.

If your dog is prone to chewing through leads, a long line should only be used while you are actively supervising them.

All of our collars and leads are handmade in our own workshop, which means we can repair, resize, or refresh them at any time. When you’re ready for a new look, we can replace the strap and reuse your existing hardware - giving your custom piece a new lease on life.
