Biothane Detachable Leash Extender + Coupler

Four Black Paws

Easily walk two dogs with our biothane leash extender + coupler. This extender + coupler features two biothane straps in your choice of color(s) fixed to an o-ring with your choice of snap hooks at one end and your choice of snap hooks at the other end. Simply attach your existing lead to the o-ring and the bolt snaps at the end of the coupler to your pups and away you go. This extender + coupler can also be used to extend the length of your existing leash for a single dog. The possibilities are endless!

The snap hooks that we use are swiveling snap hooks so that the biothane won't get twisted up on itself.

The coupler pairs well with any of our biothane leads in the shop. While we offer 5/8", 3/4" and 1" wide biothane for this coupler, the thinner widths are recommended as to not cause too much additional weight; the addition of 2 extra snap hooks will cause the leash to be heavier.

The length you choose for the coupler is the length of the biothane portion, only. The length of the o-ring and snap hooks is not included in the length.

Every piece in this line is hand crafted from coated webbing that is durable and easy to clean. It even stays flexible in cold weather! This amazing webbing is soft and has the appearance of leather but is more durable, cleanable, stronger and easier to maintain than leather. It's also:

-water repellant

-stink-resistant

-antibacterial

-stronger than nylon and leather

-cleanable with soap and water 

Ordering Instructions:

You'll start by choosing from our constantly growing color choices for your coupler! You'll also choose your width, coupler length and hardware.


Choose from your choice of width (for most dogs, we highly recommend going with the 5/8" or 3/4" width in the standard weight - 1" and super heavy weight is recommended only for large breed dogs):

5/8" width
3/4" width
1" width

Choose from your choice of snap hook color and style:

-Stainless Steel Bolt Snap

-Stainless Steel Trigger Snap

-Solid Brass Bolt Snap

-Solid Brass Trigger Snap

Please scroll through the pictures to see all available collar color choices (note: if a color does not show up in the drop down list, it is likely sold out).

Standard vs. Super Heavy:

The choice between purchasing the standard thickness leash and the super heavy thickness leash is personal preference. We DO NOT recommend the super heavy weight material for small dogs due to the additional bulk. Both thicknesses have a break strength of 750-1,000 pounds. The standard thickness material is approximately 0.1" thick and the super heavy thickness material is approximately 0.15" thick.

Additional Information:

• Each coupler is handmade from the very beginning to end; you may notice a slight variation in length from one coupler to the next
• Hand wash your biothane products with soap & water. If your leash or collar has been exposed to an especially stinky substance, you may wipe down with a diluted 10% bleach solution (1 part to 9 parts water) or wipe down with vinegar to help neutralize odors.

It is very important to note that our products are not designed to be used for a "tie out." Damage caused by using any of our products to tether a dog are non repairable. We also do not recommend tethering a dog due to the excessive risk of injury, damage and loss. If you are planning to tie your dog to a tie out or an outdoor line, please be sure to purchase items from a manufacturer that designs products specifically for this purpose.

Each consumer is responsible for determining the suitability of these products for their individual situation. Consumer accepts all responsibility by purchasing and using these products.
