The collars are suitable for dogs that pull strongly on the leash.
BioThane is a material developed in the USA, resembling leather. Thanks to its construction (polyester core, PVC coating), it is an extremely durable and long-lasting material. BioThane is 100% waterproof, very strong, yet soft and flexible (even in cold weather). It is stain-resistant and easy to clean. Additionally, the leash does not require special maintenance like a leather leash. Nelly&Dodo always uses original BioThane products with a matte surface version when making their leashes. The material provides excellent grip and is comfortable to hold.
Under normal usage conditions, BioThane leashes last longer than nylon or leather leashes.
