Letting your dog explore off-lead is wonderful, but a shaky recall makes it nerve-wracking. A long line lead bridges the gap: it gives your dog 5 to 15 metres of freedom to sniff, run and practise coming back, while you keep hold of the safety net. For nervous rescues, recovering escape artists and puppies still learning the basics, a good long line is one of the most useful pieces of training kit you can own.
Below we round up the best long line leads you can buy in the UK in 2026, from budget nylon training lines to easy-clean biothane and classic rope check cords. We cover what to look for, which material suits which dog, and how to use a long line safely, so you can pick the right one for your dog’s size, temperament and the kind of walks you enjoy.

Individual Product Reviews
Ancol Viva Long Training Line
Best for: everyday recall training on a budget.
Ancol is a long-established British pet brand, and the Viva long training line is the natural starting point for most owners. It is a simple flat nylon webbing line with a sturdy trigger clip at one end and a sewn loop handle at the other, usually offered in lengths around 10 metres in bright, easy-to-spot colours.
For the price it does everything a recall line needs to: it is light enough not to drag your dog down, long enough for proper distance work in a field, and tough enough to handle regular use. The flat webbing can pick up mud and hold water, so it is best in drier conditions or given a rinse after wet walks.
What we like: excellent value, lightweight, easy to spot, widely stocked.
Worth knowing: flat nylon absorbs water and mud, and can give a friction sting if it runs through bare hands, so gloves are wise.
Specifications:
- Type: flat nylon webbing long line
- Lengths: typically around 5m and 10m
- Attachment: trigger clip and sewn loop handle
- Material: woven nylon webbing
- Available on Amazon UK and at Pets at Home
Trixie Tracking Lead
Best for: tracking, scent work and very long distances.
The Trixie tracking lead is a favourite for owners who want maximum length. Offered in flat nylon in a wide range of sizes, including longer 15 and 20 metre options, it lets a dog range a long way ahead while you still keep contact, which suits tracking, scent games and open spaces with good visibility.
It uses a strong bolt or trigger clip and a comfortable hand loop. As with any very long line, the extra length is brilliant for confident dogs in big open areas but can be more than you need for close-up recall practice, where a shorter line is easier to manage.
What we like: lots of length options, strong clip, good for tracking and scent work.
Worth knowing: the longest versions are heavy and can tangle, so they take practice to handle neatly.
Specifications:
- Type: flat nylon tracking line
- Lengths: a wide range up to around 15–20m
- Attachment: bolt or trigger clip with loop handle
- Material: nylon webbing
- Available on Amazon UK and at selected pet retailers
Company of Animals Clix Long Line
Best for: structured recall training with a comfortable handle.
From the same training-focused stable as the Clix and Halti ranges, the Clix long line is designed with method in mind. It pairs a soft, padded handle with a strong clip and a clearly marked webbing line, so it is comfortable to hold during repeated recall sessions and gentle on the hands if your dog hits the end of the line.
It is a sensible mid-range choice for owners working through a structured recall programme, where you spend a lot of time holding, shortening and lengthening the line. The padding makes a real difference over a long training session compared with a plain webbing handle.
What we like: padded comfortable handle, training-led design, reassuringly strong clip.
Worth knowing: like all nylon it holds mud and water, and the padded handle adds a little bulk in the pocket.
Specifications:
- Type: padded-handle nylon long line
- Lengths: commonly around 5m and 10m
- Attachment: trigger clip with padded loop handle
- Material: nylon webbing with padded handle
- Available on Amazon UK and at Pets at Home
HugglePets Biothane Long Line
Best for: muddy walks, water-loving dogs and easy cleaning.
Biothane is a coated webbing that feels a little like soft, flexible plastic, and it is transforming long lines. The HugglePets biothane long line does not soak up water or mud, does not hold smells, and wipes or rinses clean in seconds, which makes it ideal for British winters and dogs that head straight for every puddle and pond.
It stays supple in the cold rather than going stiff, slides smoothly without the friction burn of dry nylon, and comes in a choice of lengths and bright colours. For owners tired of festering, muddy training lines, it is well worth the modest step up in price.
What we like: waterproof and easy to clean, no odour, supple in cold weather, smooth to handle.
Worth knowing: it can feel slightly slippery when wet, and the solid clips add a touch more weight than basic nylon.
Specifications:
- Type: biothane (coated webbing) long line
- Lengths: typically around 5m, 10m and 15m
- Attachment: trigger clip with handle loop
- Material: waterproof biothane-coated webbing
- Available on Amazon UK
Mendota Check Cord
Best for: gundog-style training, strong dogs and distance recall.
The Mendota check cord is the traditional gundog choice: a length of smooth, rounded rope rather than flat webbing. The rope construction runs freely over the ground and through the hand, resists tangling better than flat lines, and copes well with bigger, stronger dogs that would test a lightweight nylon line.
It is a premium, hard-wearing option built for serious recall and field training rather than a quick walk in the park. The rounded profile is kinder on the hands at speed, though as with any long line a pair of gloves is still sensible if your dog has real power.
What we like: tangle-resistant rope, very durable, runs smoothly, ideal for strong dogs.
Worth knowing: pricier than nylon, and the rope can still cause friction burns through bare hands at speed.
Specifications:
- Type: rope check cord / long line
- Lengths: commonly around 4.5m to 9m (15ft–30ft)
- Attachment: solid snap clip with knotted or stitched handle
- Material: braided rope
- Available on Amazon UK and at specialist retailers
Dog & Field Biothane Long Line
Best for: a premium, tangle-resistant all-weather pick.
Dog & Field is a UK brand well regarded among trainers for its biothane long lines. Like the HugglePets line it is fully waterproof and wipe-clean, but the finish and hardware sit at the premium end, with smooth solid clips and a choice of widths so you can match the line to your dog’s size.
Narrower widths keep weight down for small and medium dogs, while wider versions give extra strength for larger breeds. It is the line to choose if you want the easy-clean benefits of biothane in a hard-wearing package you will not need to replace for years.
What we like: durable premium build, fully waterproof, width choice for different sizes, trainer favourite.
Worth knowing: one of the dearer options, and the wider, longer versions carry noticeable weight.
Specifications:
- Type: biothane long line
- Lengths: typically around 5m, 10m and 15m
- Attachment: solid trigger clip with handle loop
- Material: waterproof biothane-coated webbing
- Available on Amazon UK
Buying Guide: How to Choose the Best Long Line Lead
What to Look For
The three things that matter most are length, material and the clip. The length sets how much freedom your dog gets, the material decides how the line handles and how easy it is to clean, and the clip is the single point that has to hold under a sudden lunge. Always pair a long line with a well-fitted harness rather than a collar, because a dog hitting the end of a long line at speed can jolt its neck. A back-clip or Y-front harness spreads that force safely across the body.
Long Line Types Explained
Flat nylon webbing lines are light, cheap and widely available, but they soak up water and mud and can give friction burns. Biothane lines are coated webbing that stay clean, dry and supple in any weather, making them the easy-care choice for British walks. Rope check cords run freely and resist tangles, which suits strong dogs and gundog-style training, though they cost more.
Size and Length Guide
Length should match where you train rather than your dog’s size. The shorter and lighter the line, the easier it is to manage up close.
- 3–5m: close-up recall practice, small or young dogs, and busy areas with other people about
- 10m: the all-round choice for everyday recall training in parks and fields
- 15–20m: open spaces, tracking and confident dogs that need real distance — heavier and more prone to tangling
Match the line width to your dog too: lighter, narrower lines for small breeds, and wider, stronger lines for powerful dogs.
How Much Should You Spend?
- Budget (under £15): a basic Ancol or Trixie nylon line — perfectly good for getting started
- Mid-range (£15–£25): a biothane line such as HugglePets, or a padded-handle Clix line, for easy cleaning and comfort
- Premium (£25+): a Dog & Field biothane line or a Mendota check cord built to last for years of serious training
Frequently Asked Questions
Should I attach a long line to a collar or a harness?
Always use a harness. If a dog reaches the end of a long line at speed, the sudden stop can jolt its neck on a collar. A well-fitted harness spreads that force across the chest and shoulders, which is far safer.
What length of long line should I start with?
For most owners a 10 metre line is the sweet spot: enough freedom to practise real distance recall, but still manageable in the hand. Drop to 3 to 5 metres for busy areas or very young dogs, and only move up to 15 or 20 metres once you can handle the line confidently.
How do I stop the long line getting tangled?
Keep the line off the ground as much as you can by gathering the slack in loose loops in your hand, and let it out gradually rather than all at once. Biothane and rope lines tangle less than flat nylon, and never wrap a long line around your hand or wrist.
Can I use a long line as an everyday lead?
No. A long line is a training tool for open, low-traffic spaces, not for walking along pavements or near roads. For everyday walks use a standard lead, and switch to the long line when you reach a safe, open area to practise recall.
Is a long line suitable for puppies?
Yes, and it is a great way to build a reliable recall early. Use a shorter, lighter line on a comfortable puppy harness, keep sessions short and positive, and reward your puppy every time it chooses to come back to you.
Final Verdict
For most UK dog owners the Ancol Viva Long Training Line is the best place to start: it is affordable, light, easy to find and does everything early recall training asks of it. If you walk in mud, rain and water — which in Britain is most of us — the HugglePets Biothane Long Line is the upgrade we would choose, staying clean, supple and odour-free season after season. Owners of strong or gundog breeds should look instead at the Mendota Check Cord for its tangle-free rope and serious durability.
