One sudden sprint. One squirrel. One dog hitting the end of a long line at speed.
If that long line is attached to a collar, all of that force goes straight into the neck and throat.
This is exactly why I don’t recommend clipping a long line to your dog’s collar.
Long lines can be brilliant for recall training, decompression walks, recovery periods, safe exploration, and preventing unwanted behaviour from being rehearsed. But like most dog training equipment, how you use them matters.
In this guide, we’ll look at long line safety, why I recommend using a harness instead of a collar, common long line mistakes, how long lines compare with flexi leads, and how they can help you build reliable recall without relying on shouting, panic, or tools like e-collars.
Quick Long Line Safety Tips
- Clip the long line to a well-fitted harness, not a collar
- Wear gloves when handling a long line
- Don’t wrap the line around your hand
- Avoid letting your dog hit the end of the line at speed
- Keep the line relaxed where possible rather than under constant tension
- Use a long line to prevent rehearsal of unwanted behaviours
- Reward good choices with food, toys, sniffing, movement, or access to the environment
These small details make a huge difference when using a dog long line for recall training, decompression walks, and safe freedom around distractions.
Long Line Safety: Harness or Collar?
For me personally, a collar is for ID.
A harness is for long line attachment.
A harness helps keep long line walks and recall training safer.
If your dog suddenly runs, changes direction, or hits the end of the line at speed, a collar concentrates that force around the neck and throat.
A well-fitted harness spreads that pressure more safely instead.
This is especially important for dogs who are strong, excitable, adolescent, still learning recall, easily distracted by wildlife, or prone to sudden bursts of speed. In other words, most Labradors at some point in their lives.
For long line use, I recommend clipping the line to the back attachment point of a comfortable, well-fitted Y-shaped harness.
If you’re unsure whether your dog’s harness fits correctly, read How to Fit a Dog Harness Properly. You may also find Two Dog Harness Types I Avoid helpful when choosing equipment.
If your dog wears a collar for everyday ID, make sure it fits properly too. You can read more here: Correct Collar Fitting.
Why Long Lines Are So Useful
A long line is not just a longer lead.
Used well, it is a management tool, a training aid, and a safety net.
Long Lines for Recall Training
Long lines are brilliant for dog recall training because they allow your dog to practise coming back from a distance before they have full off-lead freedom.
This is one of the biggest benefits of long line recall training: your dog can practise the skill in real environments while you still have a safety net.
So instead of your dog hearing “come”, ignoring you, and carrying on to investigate the dead thing they found in the hedge, the long line helps you safely guide good choices while building reliable recall.
It helps prevent dogs from repeatedly practising ignoring the recall cue, which is a huge part of building reliability.
If your dog is not ready to be fully off lead yet, you may also find Reliable Recall Training Before You Go Off Lead and First Time Letting Your Pup Off Lead useful.
For more structured support, my Rapid Recall Online Course goes into long line handling, recall foundations, and how to build reliability around distractions.
Long Lines for Prevention
Long lines are also excellent for prevention.
They help stop dogs rehearsing unwanted behaviours such as:
- chasing wildlife
- charging over to other dogs
- scavenging
- running towards livestock
- ignoring recall around distractions
- disappearing into the next postcode because they spotted a squirrel
This links closely to the second stage of the HPDT behaviour framework: Prevent Practice: How to Stop Unwanted Dog Behaviour.
If a behaviour works for your dog, they are more likely to try it again. Long lines help you reduce opportunities for those behaviours to pay off.
If your dog is likely to chase wildlife, using a long line can be an important part of keeping them, wildlife, and livestock safer. You may also find How to Stop Your Dog Chasing Wildlife useful.
Long Lines for Decompression Walks
Long lines can also give dogs more freedom to sniff, explore, and decompress safely.
This can be especially helpful before asking for more focused training, such as loose lead walking. Some dogs need time to sniff and take the edge off before they can concentrate properly.
If loose lead walking is something you’re working on, read Loose Lead Starts Here.
Long Lines During Recovery
Long lines can be useful during recovery periods too.
Bear recently had an operation, and using a long line gave him a bit more freedom while helping stop him charging around like he’d just had six espressos.
It allowed controlled freedom, which is often far more realistic than expecting an energetic dog to suddenly behave like a retired librarian.
Long Line vs Flexi Lead
Flexi leads are one of those pieces of dog equipment that divide opinion.
I don’t think every flexi lead user is doing something terrible, but they do work very differently to long lines.
| Flexi Lead | Long Line |
|---|---|
| Often creates constant tension | Can be handled with a loose, relaxed line |
| Dog may learn that pulling creates more distance | Better suited to structured recall practice |
| Less precise around distractions | Allows more controlled distance management |
| Can be risky if dropped | No bulky handle chasing the dog |
| Harder to manage safely in busy places | Easier to shorten, gather, and control when handled well |
| Not ideal for teaching long line recall training | Excellent for building recall gradually |
Flexi Leads
Flexi leads often keep constant tension on the dog. This means the dog learns that pressure on the lead is normal, and in some cases, that pulling creates more distance.
They can also be harder to manage around roads, other dogs, livestock, cyclists, and sudden distractions. If dropped, the handle can chase the dog, which is the sort of chaos nobody needs on a Tuesday morning.
Long Lines
A long line gives you more control over distance, timing, recall practice, and prevention.
It is generally a better option for structured recall training because you can manage the line, reward check-ins, prevent rehearsal, and gradually build freedom in a safer way.
Long lines still need proper handling, but they give you more training options than a flexi lead.

Why I Prefer Waterproof BioThane-Style Long Lines
The 10m waterproof long line I use and recommend is a BioThane-style long line.
I prefer this to a fabric long line because it doesn’t absorb half the British countryside every time it rains.
Waterproof long lines tend to:
- stay lighter when wet
- wipe clean more easily
- dry quicker
- drag through damp grass and mud more smoothly
- smell less offensive after a wet walk
For UK dog walks, this is not a small detail. It is basically survival equipment.
A waterproof dog long line is especially useful if you regularly walk through wet grass, muddy fields, woodland paths, or anywhere your dog believes every puddle deserves a full investigation.
How To Hold a Long Line Safely
Long line handling is a skill in itself.
The aim is not to hold on for dear life and hope for the best. The aim is calm, planned handling.
- Hold the line in loose, manageable sections
- Gather the line gradually as your dog comes closer
- Release more line smoothly as your dog moves away
- Keep an eye on where the line is in relation to legs, paws, people, bikes, and other dogs
- Shorten the line before your dog reaches a high-value distraction
- Avoid wrapping the line around your hand or wrist
- Wear gloves to protect your hands
Good long line handling should feel quiet and prepared, not reactive and panicked.
If you regularly feel like you’re being water-skied across a field, the setup, environment, line length, or training plan probably needs adjusting.
Common Long Line Mistakes
Long lines are brilliant when used properly, but they can cause problems when they are handled badly.
1. Attaching the Long Line to a Collar
This is the big one.
If your dog hits the end of the line at speed, you do not want that force going through their neck or throat.
Use a well-fitted harness instead.
2. Letting the Dog Hit the End at Full Speed
A long line should not become a bungee cord.
The aim is not to let the dog build up speed and then suddenly stop them. The aim is to manage the distance, stay aware of the environment, and prevent that big jolt from happening in the first place.
3. Wrapping the Line Around Your Hand
Please don’t wrap the long line around your hand.
If your dog suddenly accelerates, the line can tighten quickly and cause injuries or friction burns.
I recommend wearing gloves for long line handling. I learned that one the hard way after a long line burned straight through my hand.
4. Keeping Constant Tension on the Line
A long line is not for dragging your dog around.
Ideally, the line should be relaxed where possible. Constant tension can create frustration, encourage pulling, and reduce the dog’s ability to move naturally.
5. Giving Too Much Line Too Soon
More distance means more responsibility.
Some dogs are not ready for the full 10 metres straight away, especially around high-value distractions like wildlife, other dogs, or livestock.
Start with a manageable amount of line and increase freedom as your dog shows they can cope.
6. Poor Awareness Around Other Dogs
Long lines can become trip hazards around other dogs, people, children, bikes, and pushchairs.
If the environment is busy, shorten the line and manage the space.
This is also why I’m not a fan of extra clutter hanging from leads. You may find Poo Bag Holders on Leads relevant if you like keeping your lead handling clean and practical.
Do You Need an E-Collar for Recall?
Personally, no.
I believe a long line gives you a safer and kinder way to build recall around distractions without relying on fear, pain, panic, or punishment.
A long line helps you:
- prevent rehearsal
- guide good choices
- reward successful recalls
- build distance gradually
- train safely around distractions
- protect wildlife and livestock
- avoid giving your dog full freedom before they are ready
Reliable recall is not built by waiting for your dog to get it wrong and then punishing them.
It is built through repetition, reinforcement, prevention, gradual proofing, and lots of successful practice.
This is why I see long lines as such a useful force-free alternative for dog recall training around distractions.
If your dog struggles around wildlife, read How to Stop Your Dog Chasing Wildlife. You may also find Emergency Recall for Dogs helpful.
For countryside walks, it’s also important to follow the Countryside Code, especially around livestock and wildlife.
My Recommended Long Line Setup
If you want to use a long line safely, the setup matters.
Here’s what I’d recommend:
- 10m Waterproof Long Line
- Ruffwear Front Range Harness
- Gloves for Long Line Handling
- Dog Gone Good Treat Bag
- JR Recall Treats
- JR Chicken Pate
- Arden Grange Liver Paste
- Pocket Magnet Tug
- Tug Toys
- Silicone ID Tag
- Tractive GPS Dog Tracker
A long line is a safety tool, but good rewards matter too. If your dog finds the environment exciting, you need reinforcement that can compete with the environment.
Food is useful, but don’t forget that toys, tug, movement, sniffing, and access to the environment can all be powerful reinforcers too.
If you want more support with recall, you can also look at my Rapid Recall Online Course or book a private consultation.

Final Thoughts
Long lines are not about restricting dogs.
Used properly, they can actually give dogs more freedom.
More safe exploration. More successful recall practice. More decompression. More prevention. More safety.
But please, clip the long line to a harness rather than a collar.
Your dog’s neck will thank you. Probably not verbally, because they’re too busy trying to find something questionable in a hedge, but still.
FAQ
Should a long line attach to a harness or collar?
I recommend attaching a long line to a well-fitted harness rather than a collar. If a dog suddenly hits the end of the line at speed, a harness helps spread the pressure more safely instead of placing it directly around the neck and throat.
Are long lines good for recall training?
Yes. Long lines are excellent for recall training because they allow dogs to practise coming back from a distance while still giving you a safety net. Long line recall training is especially useful when dogs are not ready for full off-lead freedom yet.
What length long line should I use?
A 5m to 10m long line is commonly used for recall training and decompression walks. I often recommend a 10m long line, but some dogs may need to start with less distance at first.
Are waterproof long lines better than fabric long lines?
I personally prefer waterproof BioThane-style long lines because they stay lighter when wet, wipe clean more easily, dry faster, and don’t absorb half the British countryside every time it rains.
Should dogs pull on long lines?
No. Long lines should ideally be handled calmly with as little constant tension as possible. The goal is not to drag your dog around, but to provide safer freedom and prevent rehearsal of unwanted behaviours.
Can a long line replace an e-collar for recall training?
For many dogs, yes. A long line provides a force-free way to manage freedom, prevent rehearsal, and build reliable recall gradually without relying on fear, pain, or punishment.
