A long-line is a long training lead, typically 5 to 15 metres of biothane or webbing, attached to a well-fitted Y-front harness. It gives a dog significantly more freedom than a regular lead while keeping them under your control. Long-lines are the standard tool for recall training, sighthound walks, and any environment where full off-lead is unsafe but full-lead is too restrictive.
When to use one
The most common situations:
- Recall training — letting the dog roam, then practising recalls before they reach the end of the line
- Sighthounds and high-prey-drive dogs — Greyhounds, Lurchers, Beagles, Salukis, Whippets
- Young / adolescent dogs still building reliability
- Reactive dogs in environments where space management matters
- Recently rehomed dogs in unfamiliar environments
- Very wooded or tricky terrain where sight lines are limited
What to look for
- Material: biothane or webbing, not rope. Rope tangles, snags, and causes friction burns.
- Length: 10m / 33ft is the most useful all-rounder. 5m for tighter spaces, 15m+ for sighthound coursing.
- Width: ~15–20mm. Wider distributes force better.
- A bolt clip rather than a snap clip (more secure).
Critical: never on a collar
A long-line attached to a collar can cause serious neck injury when the dog hits the end of the line at speed. Always attach to a Y-front harness.
Common mistakes
- Letting the line drag through wet/muddy grass and then handling it (cold, dirty, slippery)
- Wrapping it around hands or wrists (rope-burn / pull injury risk)
- Using it as a primary lead in busy areas (it's training equipment, not a substitute for a 2m lead in town)

FAQs
Are long-lines the same as flexi-leads? No. Flexi-leads are thin retractable cords on a handle that snap, tangle, and don't allow controlled handling. Long-lines are non-retractable webbing or biothane that you handle directly.
At what age can a puppy use a long-line? From whenever the puppy is comfortable on a lead, typically from 12 weeks. Use a lighter, shorter line (3–5m) for small puppies.
Will my dog hate it? Most dogs love them, the freedom is greater than a normal lead, and there's no aversive feedback when they hit the end (assuming you slack the line as they near the limit).
