BioThane® Dog Leash

Regular price $59.99

Our Biothane® Leashes are waterproof, stink-proof, highly-durable, soft to the touch, and feature a variety of color choices! Best of all, a quick rinse under water is all it takes to get your leash looking new again.  We offer two choices of hardware; "Gold (Solid Brass)" and "Silver (Stainless Steel/Plated Brass)." Both are rust-proof and highly durable.

Our leashes are made with ultra-durable 3/4" BioThane webbing, with a breaking strength of 1,000lbs per square inch. 

Clasp Options:

When it comes to clasp selection, we've got you covered! All of our leashes come with your choice of swivel carabiner-style clasp. We offer two styles of twist-lock gates; all black, and black with a silver gate. We typically recommend all black for leashes that use brass hardware so the metals don't clash visually. We also offer a Black AutoLocking Carabiner clasp. For information on how these kinds of clasps work, please refer to our explainer slide in the gallery. Please note, while these carabiners are very strong and durable with a breaking load of 880lbs, they are not climbing rated. The main benefit of the carabiner clasp is that it is an extremely lightweight option with heavy duty performance.

(Trigger clasps are available upon request for stainless steel only.)

Leash Safety Tips:

  • Inspect your gear before each use for wear and tear that could cause safety issues.
  • Before clipping to the d-ring, unscrew the lock gate to ensure the clasp can fully close, and then use the lock to secure the clasp shut. If using an auto-locking carabiner clasp, never attempt to force it to shut. To use properly, release the clasp when open and allow it to shut and lock on it's own.
  • Always make sure you are clipping directly to the d-ring and not the tag ring.
  • Never use a leash or collar for anything other than it’s intended purpose. Misuse of gear can lead to safety issues.
  • Never leave your dog unattended while the leash is attached. It is also not advised to allow your dog to drag their leash behind them on the ground.
  • It is the buyer’s responsibility to determine what gear is appropriate for their dog’s size, strength, and activity level. Mutt Pack is not liable for any injuries or damage that may occur as a result of use.

Return Policy:

We want you to dig your gear as much as we do! If you don't love your order, you can return any non-custom items that are in their original packaging and have not been used or worn within the first two weeks (14 days) of delivery.

Please note, we do not allow returns for any BioThane products as these are all custom-made items and we do not allow returns on discounted or clearanced products.

For custom (all BioThane) products, please reach out if you have any questions before ordering. If you would like to preview a color palette we can assist with that to make sure your design is to your liking. It is also important to note that it is the buyer's responsibility to properly measure their dog. Please verify that you are measuring correctly for the item you are buying as we do not accept returns if the wrong size is ordered. If you have any questions about fit, please reach out before placing an order so we can help you!

International (non-U.S.) orders are also not eligible for returns.

Love this product

I love this product!!! I purchased 2 collars, one leash, and two connectors to walk my two already large puppies.

The leash is lightweight but so strong and feels so comfortable in my hands. Unlike other leashes I’m certain this won’t burn my hands if the dogs should yank too hard. It’s soft and pliable but super strong. I’m only sorry I didn’t purchase a separate leash for when I get them more under control or when not just walking them myself. I refrained due to cost but now clearly will be ordering a second leash and 2 Fi collars when we go hiking.

My new favorite leashes/collars and so thrilled not to have to wash them every time these boys decide to roll in the mud.

Well worth the price and I forgot to mention, probably the nicest packing job. I felt like I received a gift in the mail.

If you’re at all on the fence about purchasing these products don’t be. They’re well worth it!

My boys and I are very satisfied! Thanks MuttPack😊

Amazing service

Michelle was responsive to my questions immediately, with good feed back. I mentioned I was going hiking the next day and the following weekend 2/12 in the Adirondaks. My leash came yesterday 2/7, can't wait to use it. I found Mutt Pack on the Fi website and had gotten a collar a few weeks ago from another retailer and I wish I had gotten the collar from Mutt Pack too. I have 5 dogs so chances are, they will need replacements and I know where I will be going! Thank you Michelle. We hiked today, 3 Jack Russels, 1 Rottenweiler, and the Beagle with his new leash, it was perfect...then there was a squirrel.

My dog walker told me to get this type of leash and I won’t go back! Love the color and mutt pack tag too😊

Mary LoveBeautiful leas

Beautiful leashes with the safest clasp one could imagine! Unfortunate that one could not be made in a 15 foot length for working.
It seems it should be so easy!
