Coal Biothane leash with auto-locking carabiner on a mossy rock
What you're buying

Built for long-line training and recall work.

A long, waterproof Biothane line in 15, 25, or 35 feet, with the same auto-locking carabiner and bartacked stitching as the rest of the line-up. When it drags through a puddle, you wipe it off and keep training. Sewn by hand in our Seattle shop.

Recall training

Best for practicing recall in open fields. Let them range out while you keep hold of the other end.

Fields · Recall · Parks

Decompression walks

Best for sniffy, low-pressure walks where the dog sets the pace and you just follow the line.

Trails · Sniff walks

Distance work

Best for new trainees and dogs who need a little space, in open areas where you can give them room and still close the gap when you need to.

Before you buy

The questions we actually get.

Which length should I get?

The 25 ft is the one most people take: enough room for real recall work without a pile of line to manage. 15 ft suits a backyard or park for basic practice, and 35 ft is for wide-open spaces and serious recall or scent work. Not sure? Email hello@hambospups.com and we'll help you pick.

Which color should I get?

Hunter Orange is the easiest to find in tall grass, which matters when you're coiling 35 feet of line. Water Moss is our bestseller if you'd rather blend in.

Is it okay for a big or strong dog?

Yes. The webbing is rated to 825 lb, every load point is bartacked, and it uses the same auto-locking carabiner as the rest of our leashes. Keep a line this long for training and open spaces rather than city sidewalks, since that much line is hard to manage in tight quarters.

Is it really waterproof?

Completely. The fibers are sealed inside the coating, so nothing soaks in. It won't absorb water or hold smell, and mud rinses right off, which matters on a line this long that spends a lot of time on the ground.

Can my dog chew through it?

It's tough, but no line is chew-proof and we won't claim otherwise. Don't leave it alone with a bored chewer. If you've had a chewing accident, see our Accident Replacement Program.

How do I clean it?

Wipe it with a damp cloth, or rinse it under a tap. A little dish soap and warm water if things get really mucked up, which happens fast with a line that drags on the ground. Do not oil or condition, as this can break down the coating.

Can I return it if it's not right?

Yes. Unused gear can come back within 30 days. You cover the return shipping, and there's a 20% restocking fee. Used gear we can't take back, because we can't resell it.

How fast does it ship?

Every drag line is sewn by hand in our Seattle shop. In-stock orders leave within 3–5 business days, and most go out same or next day. Free shipping over $50 in the lower 48.

Accident Replacement program

For when things happen out there.

Chewed through, shut in a car door, crushed in a tailgate. Dogs are hard on gear. If yours is damaged beyond saving, send us a photo and we'll take 40% off a replacement. We can't cover lost gear. We have to see the damage to replace it.
