Q: My old leads get soaked and smell. Will this one do the same?

A: No - Biothane is waterproof and odour-resistant. Mud and water wipe straight off, ensuring your lead stays clean and fresh, even after excessive use.

Q: I need a lead strong enough for a powerful dog. Is Biothane reliable?

A: Yes - Biothane is a lot more durable than standard materials, we also use strength tested hardware which adds to the safety and control given when using a Sledline lead. They are designed and built to handle the power of medium and large breeds.

Q: Leads I’ve tried before are hard to grip in bad weather. How is this different?

A: Biothane stays grippy even when wet and won’t absorb water, giving you control in all conditions.

Q: How do I stop a lead from cracking or wearing out quickly?

A: Biothane won’t crack, stretch, or fray like leather leads. With normal use, it keeps its strength and flexibility for years.
