Lead Extension – Waterproof BioThane® Custom Dog Lead

BIOTHANE®
BioThane® is a premium brand of coated webbing, created by bonding a PVC or TPU (thermoplastic polyurethane) coating to a polyester or nylon core. The result is a strong, durable, and waterproof material that’s lightweight, easy to clean, and resistant to chewing and scratching.

We only use genuine BioThane® because of its proven quality and reliability – unlike cheaper alternatives on the market, it maintains its strength, finish, and performance over time.

HARDWARE
Premium hardware, cast from solid brass, selected for maximum strength to ensure our products remain rust-free for life. All hardware is kept securely in place with strong solid brass rivets.

Solid brass is a natural metal so our "gold" hardware may arrive with a little tarnish, especially when travelling snugly against leather. This is completely normal and easily polished – a quick wipe brings back the shine. Over time, brass also develops a warm, natural patina that many owners love. If you prefer hardware that stays bright without patina, you may like to choose our silver option instead (nickel-plated brass or stainless steel).

CRAFTSMANSHIP
Our BioThane® dog leads are custom made with quality craftsmanship and thoughtful design that prioritises your dog's comfort and safety.

Each dog lead is meticulously handmade, and our nameplates are hand-stamped. Minor tooling marks or inconsistencies in the stamping enhance the unique charm and human element of your custom dog lead.

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®.

WIDTH
3/4" is a good size for most dogs. 1/2" suits small breeds and 1" suits large breeds or if you like a thicker handle.

Your choice of either gold (solid brass), silver (nickel-plated solid brass) or matte black (PVD solid brass) hardware.

NAMEPLATE
If you would like a nameplate added, your dog's details will be hand-stamped and clearly seen on the solid brass or stainless steel nameplate.

Nameplate Dimensions:
Small (for 1/2" and 3/4" wide leads) - 50 x 9.5mm - up to 2 lines of information in 2.5mm text
Large (for 3/4"and 1" leads) - 70 x 16mm - up to 3 lines of information in 3mm text.

If your dog needs to be tied up or left unattended for a while, we recommend using a heavy-duty lead made for that purpose, and saving this custom lead for walks and training. While our leads are extremely sturdy, and will withstand forceful tugging, there are determined dogs out there for which any lead is no match!

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.
