Our leashes, collars, and accessories are made from BioThane. BioThane is a woven polyester webbing with a soft PVC coating. It’s durable, lightweight, waterproof, odor proof, antimicrobial (stink prood), and easy to clean. It is an ideal material for working with dogs as it does not absorb water, dirt, mud, or odor - no more dirty, stinky rope, webbing, or leather leashes! BioThane is softer, more supple, and easier to grip than nylon, making leash burn less likely. It’s easier to maintain and more affordable than leather. BioThane comes in a variety of vibrant colors and different widths so the options for customization are endless!

Leash sizing is very individual! It will depend on you and your dog's size, intended uses, environment, and your comfort level handling a leash. We always encourage customers, when they can, to consider a slightly longer leash. It will give them more flexibility and to help their dog to have more freedom, autonomy, and opportunities to sniff on their walks! Read more about leash sizing.

We offer a wide variety of leash customization options to meet you and your dog's needs. Read all about our customization options. That said, there is nothing wrong with opting for a standard leash with a loop handle!

We offer our leashes and long lines with Classic Brass or Sport (autolocking Carabiner) hardware. Learn more about our different hardware options.

A long line is a leash that is longer than the "standard" leash length of 6 feet. It's a simple but incredibly versatile tool! Typically, you attach the line to the back of your dog’s harness and simply leave it on your dog during a neighborhood walk, sniffy walk, hike, beach romp, or training/play session. You can hold the line with slack, or, if leash laws allow and your dog's recall is reliable, simply drop it and let it drag, picking it up as needed. Long lines can be helpful for training recall and loose leash walking, or just for giving your dog a little extra room to sniff and move their body freely. You can also use a long line while traveling, camping, backpacking, or anytime you want to give your dog some extra freedom while keeping everyone safe. Learn more about long lines here.

No! Just like nylon, rope, webbing, or leather, BioThane is NOT chew proof and a determined dog (or a puppy) will be able to damage or even chew all the way through the line. For this and other safety reasons, you should never leave your dog unattended wearing any leash or long line. If you need to tie your dog out for any reason, please use a line made expressly for that purpose, such as a cable.

BioThane is incredibly strong. It has a tested break strength of at least 1000 lbs per inch of width. BioThane gets its strength from its woven webbing core, while the PVC coating protects the webbing from damage and UV deterioration. You do not need to worry about an intact, undamaged BioThane line breaking, even with determined pulling from a strong dog. If the webbing core of your leash is damaged, the strength of your leash may be compromised. Please inspect your leash and hardware regularly.

BioThane is a cinch to clean! Just rinse off and wipe down with a towel. For a more thorough clean, or soak in a bowl of water with mild soap, clean gently with a sponge or a towel, rinse thoroughly and towel dry. To sanitize your leash, wipe down with a sanitizing wipe or spray down and allow to air dry. 

If you work at a daycare or training facility where the lines are being used by multiple dogs, it is best to clean them often with a germicidal solution such as Kennel Sol. Dilute according to instructions, then spray, wipe, or dunk leashes in the solution and allow to air dry. Learn more about cleaning your BioThane gear here.

Some basic care and maintenance will help ensure that your leash hardware stays intact and functioning for years to come. Salt water and sand will weather your hardware over time. After a trip to the beach, a muddy hike, or any other time your leash hardware is exposed to salt water, sand, mud, or other grime, make sure to rinse your leashes well and towel or air dry. Over time, dirt, grime, and salt can collect in the spring mechanism of a standard bolt snap, resulting in a “sticky” clasp. To fix this, first soak in soapy water and rinse the hardware well to get any larger pieces of dirt/grime out. Then add a few drops of WD-40 or another penetrating oil inside the clasp where the spring is. Open and close the clasp repeatedly until it is moving more smoothly. Do not store your gear wet. Rinse and dry after use and hang up for storage.

Under normal use BioThane does not get sticky or tacky. BioThane may get sticky or tacky with exposure to certain chemicals such as DEET.

BioThane will remain flexible and durable in cold weather.

Yes! BioThane is developed with extensive testing to ensure that it is colorfast (color won't bleed or transfer to fabric or fur). It is possible for brass hardware to tarnish your dog's fur.
