  • Why Biothane?

Walk multiple dogs with our NEW coupler! Simply clip your leash (or a matching leash from our shop) onto the end of the coupler! This coupler is 3/4" wide and comes in 12", 18", and 24". Our durable BioThane® coupler is made from genuine 520 standard BioThane®. In addition, it is odor-proof and water-resistant, and above all - made to last. The vibrant colors are eye-catching, on-trend, and beautiful for both you & your four-legged friend.

Taking care of your Biothane gear is easy! Just follow these simple tips:

• Handwash your Biothane gear with mild soap and water, then dry it with a soft cloth.

• Brass hardware will develop a patina (tarnish) over time, but you can minimize this by regularly polishing and cleaning it.

• Don't worry if nickel-plated and matte black hardware shows wear and tear over time—it's normal and won't affect its integrity. To keep nickel-plated and matte black hardware in great shape, wash them with mild soap and water and dry them thoroughly after use, especially if they've been in water, like salt water, to prevent rusting.

While BioThane® is incredibly versatile and repels most of the dirt and grime it encounters, please note that it is not completely stain-proof in all circumstances. Regular cleaning is recommended to keep your BioThane® gear looking new.

We only use Genuine BioThane® on our leashes and collars. BioThane is a Polymer coated webbing that is durable, waterproof, and easy to clean. BioThane® rinses clean in seconds, will not mold or mildew, and will not absorb odors. BioThane® is manufactured in the USA.
