Redline K9 All Weather Black Biothane Dog Leash 3/8". Made from revolutionary 520 Biothane®, our All Weather Beta Biothane Dog Leashes are 100% waterproof, remain soft and flexible to -20F, wipe clean in seconds and are easy to grip, even when wet. They have the look and feel of leather, provide exceptional grip and strength and are completely maintenance free. 3/8" 520 Biothane® has a break strength of 375 lbs.

All sizes can have a handle or no handle and brass or stainless steel hardware. *Note stainless steel hardware is more substanial than the equivalent brass hardware. If you want smaller, lighter hardware, choose brass.

Biothane Dog Leashes come standard with a heavy duty snap, an o-ring in the handle on 3' & 4' lengths and are stitched with heavy waxed nylon thread. They provide unmatched performance in any weather conditions. 

We can also make custom leads/lines in any length up to 100'!

Note: the 3/8 and 1/2 have smaller clips and 5/8 and 3/4 have larger clips.

Choosing the Right Width
While width might not be the first thing you think of when considering what kind of leash to buy, it is a factor in selecting the right leash.

Narrower leashes 3/8", 1/2"
Small dogs or young and small puppies will want a thinner leash because these are lighter and less restrictive. With a puppy, you may need to upgrade later to a thicker leash depending on their breed and temperament.
Wider leashes 5/8", 3/4"
If your dog is a chewer or a strong puller, you’ll want to choose a thicker leash. A good width will provide more strength and keep the leash from snapping under tension if your dog pulls.

We carry all-weather black biothane dog leashes in the following sizes:

I'm very happy with this leash. It is strong, well-made, and easy on my hands. The leash I received also has a brass ring on the handle that allows me to buckle the hook to the handle, forming a loop so that I can carry it over my shoulders when it's not in use.

This is my fourth leash I've purchased from this company. For me, the weight and feel of it is perfect for K9 Nose Work practice and trialing. I prefer this over leather, and by far, is my favorite biothane leash. I've handled other biothane leashes from my friends, and I still like these the best.

I am very satisfied with this product. I have a 6 month old rottweiler and this long leash compliments her stage of training perfectly.
