DRAG LINES for Nose Work, Tracking & Schutzhund / IPO :

Custom Round BioThane Drag Line

Drag lines are basically long lines with no handle at the end so there is less chance of the line getting caught on something while it's dragging along the ground.

Round BioThane® makes great drag lines for dog training and for canine sports requiring long lines.

Distance markers can be placed at requested intervals so you can easily keep track of the amount of line let out.

DECIDE ON WHAT LEngth you want:

Our Shopping Cart below separates the lines into four groups based on lengths:

1) Short Line: This is a short line, from 3′ – 8′ long.

2) Medium Line: These lines are from 9′ to 20′.

3) Long Line: These lines are from 21′ to 30′.

4) X-L Line: Very long, from 31′ – 40′.

** If you are looking for a longer or shorter length,
email me. **

The length of the leash is measured in FEET and INCHES from the end of the snap where it attaches to the line to the end of the line, handle or stop.

Choose from Solid Brass or Nickel Plated Brass
Length: 1.75" / Weight: 0.4 oz (about 2 Quarters)

Large Snaps*

Our Stainless Steel snaps have the largest eye for the thickest D or O-rings and can handle the toughest pullers such as Rotties, GSDs, Mastiffs and other strong breeds..

Medium: Length: 2.5" / Weight: 1.4 oz

* = Large Stainless Steel snaps and Trigger Snaps are an additional fee.

Bolt snaps are generally made in three metal types:

  • Zinc: Almost always nickel plated, these are the most commonly used snaps for leashes.
  • Brass: These are stronger than zinc and more resistant to corrosion. They come in many finishes. Our snaps are of the highest quality in both polished brass and nickel plated brass.
  • Stainless Steel: The strongest of all snaps. We use a marine grade stainless steel snap.​
4:  HANDLE

CHOOSE YOUR HANDLE TYPE:

All lines come standard with an 8″ handle.

You can customize further by choosing a different option:

  • O-ring in Handle
  • Stop at End (instead of a Handle)
  • Stop at End with O-ring
  • Nothing at the End (Drag Line)
Round biothane leash with o-ring
  • Add an O-ring in the handle
round biothane long line with stop at end
  • If you don't want a handle but still want to have something to hold on to at the end of the line, choose a Stop at End. There is still enough space in the loop to add a carabiner or an O-ring.
5:  OTHER OPTIONS
  • Have a really STRONG, HIGH-DRIVE dog?
  • Are you looking for a short leash or strap?
  • Consider a Double Clamp at the Snap for extra strength.

Thank you so much for the super fast service for my two biothane rope tracking lines! I like them so much better than the flat ones as these are much lighter and easier to hold yet they are strong enough for me to handle my fast Goldens in the field!
Lorie Jolly
I love mine, have been using it daily for over a year, still brand new. So much easier to handle and store than the flat one.
Yara S.
I absolutely love the round Biothane leashes. I originally had flat Biothane when I started Nosework but found that, with carpal tunnel in my hands, I really had no feel for the leash. I them switched to roping reins...nice feel, light but not quite long enough for my fast moving dogs. I then heard of round Biothane, found Rosana's site and ordered 2 12 foot leashes. I love them...I can feel them in my hands, grip them or feed them out as necessary and my dogs like the increased freedom that the extra length gives them. I have finally found leashes that I am totally happy with and absolutely recommend them!!!

I've had my 10 ft one for at least 4 yrs and it performs just as it did on day one. I recently purchased the 15 ft one. Both are great!
Karen O.
I got my leash and it is perfect! I love the round vs. Flat and the color is a perfect match for her harness I'll be doing another order for another regular leash in the next few weeks I hope
Susan M.
I have three of Rosana Cortes Dropkin's leashes in different lengths, colors and snaps. Great leashes. Lightweight and super easy to handle, store and clean. ❤ Not just for nosework but were great to use at the beach when we went a couple weeks ago.
