Biothane® is a trademarked artificial material that has the look and feel of leather, but without the problems that comes with leather. It’s basically a polyester webbing with a TPU or PVC coating that makes it a nearly indestructible dog collar that is also waterproof, and easy to clean.

Biothane® is strong, durable, and pliable. It comes in various widths, thicknesses, and colors. One aspect I truly appreciate is just how low maintenance Biothane® is compared to leather.

It doesn’t snag on brush when I’m running my dog and it doesn’t get wet or soggy. Very light, it doesn’t weigh heavy on my dog when she is tracking.

Biothane® Can Take a Beating

Cleaning Your Biothane® is a Breeze

It’s a dog eat dog collar and leash world out there, but Biothane® dog collars and leashes stay strong in the face of, well, a dog’s face. Even the strongest leather can be worn down after a few too many chews. Biothane® coated webbing, on the other paw, makes for the best dog collars on the market today.

Nobody wants to deal with a dirty dog collar or leash. Unfortunately, dogs aren’t as focused on keeping their collars or leashes clean. Whether it’s from the rain or the mud your dog decided to roll in, leather collars can become dirty and dried out over time and begin to stink.

Biothane® is waterproof, stink-proof, and headache proof for dog owners. When it gets muddy or soiled, simply wash it with soap and water and wipe it dry.

Super fast shipping!!! The rope is top notch! Love this addition and definitely recommend it! Excellent craftsmanship. Sam is great!

Our HANDSITCHED 1/2" Leashes come is a multitude of colors. The DOUBLE X pattern can only be handstitched. Once you feel the quality of our stitching you will be hooked. We personally guarantee each leash is made to with just less than 800lbs of pressure.

Our 3/4" Leashes come in multiple colors. They are held together with solid brass Chicago screws. Each screw is secured in place with red Loctite.  Even a heat gun will not loosen the screws once the Loctite settles.  The BioThane® will melt before the screw can be loosened.


Absolutely love this leash! Easily my favorite that I’ve owned. Amazing quality and feel - excellent customer service as well. Highly recommend buying from Sam!!!

BFF Pet Services review of MAK9’s Biothane Tracking Lead

I had talked to Sam on the phone. I talked to him about an idea that I had for a leash. He told me that I would be better with a MAK9 leash. He made my leash in Orange Biothane. Very very nice. Very good control than with anything else I have been using. I Would highly recommend Sam’s input before you get something. You won’t be sorry. I couldn’t figure out how to add a picture of it.

I am very happy with this lead. My red bone coon hound needs to stay on a lead so she doesn’t get lost and this allows us to romp in the woods and river together. Giving her independence and safety. it doesn’t tangle easily, is durable, highly visible. and has buoyancy. I am very happy with it.
