A slip lead is not cruel. A slip lead used on constant tension is. The whole tool depends on one thing: the loop must release the instant your dog stops pulling. If it never goes slack, you are not training, you are towing.
Ask about slip leads for dogs online and you will get two camps shouting at each other. One says they are a choke chain with better marketing. The other says everyone in the field uses one, so what is the problem.
Both are answering the wrong question. A slip lead is not good or bad on its own. It is a piece of rope that does exactly what your hands tell it to. So the honest question is not are slip leads cruel, it is am I using this one properly.
I make slip leads and slip collars by hand in Oxford, so I get to hear what happens after people take them home. I also got this wrong myself with Boris when he was a puppy, which is the only reason I can describe the mistakes so precisely.
Are slip leads cruel? The honest answer
No, and the reason is worth understanding rather than taking on trust.
A slip lead works on pressure and release. Tension tightens the loop, and the moment tension goes, the loop opens again. The information your dog receives is not the tightening. It is the release. That is the bit that says yes, that, do more of that.
Which means a slip lead sitting under constant pressure has stopped communicating anything at all. It has become a rope that is permanently tight around a neck, and at that point the objection is completely fair.
So the tool is not the variable. The slack is.
What a slip lead actually is
One continuous piece of rope that is both the lead and the collar. It goes over the head, it tightens when the dog pulls into it, it loosens when the dog stops. Nothing to clip, nothing to fasten, on and off in a second.
A slip collar is the same loop and the same action without the lead attached, so it stays on the dog and you clip your own lead to the ring. If you are trying to work out which of the two you actually want, that is a buying decision rather than a technique one, and it is covered properly on the slip leads and slip collars page.
This article is about the other half: making the thing work once it is on your dog.
The one detail that decides everything
If you remember nothing else from this page, remember this.
The loop sits high on the neck, just behind the ears. Not at the base of the neck where it meets the shoulders.
There are two reasons, and only one of them is the one people usually give.
- Welfare. Low on the neck is where the trachea is. High up, behind the ears, there is far less to press on.
- It actually works. High on the neck is the most responsive part of the dog. A signal there is light and obvious. The same signal at the base of the neck is where a dog has the most leverage, and it will simply lean into it, which is what most pulling looks like.
So the kind position and the effective position are the same position. That is genuinely lucky, and it is why fitting matters more than anything else in this article.
How to fit a slip lead correctly
| Step | What to do |
|---|---|
| 1 | Form the loop and find the stopper, the ring or knot that limits how far it can close |
| 2 | Slip it over the head from above rather than pushing it on from the front |
| 3 | Slide it up so it sits just behind the ears, high on the neck |
| 4 | Set the stopper so the loop closes to snug, roughly two fingers, and no further |
| 5 | Test it: light tension should snug it, and letting go should drop it straight back to slack |
Step 5 is the one to keep checking. If releasing the lead does not open the loop on its own, either the stopper is set wrong or the rope is not running cleanly, and until that is fixed the lead cannot do its job.
The lead I make for this is The Strand, a 6mm rope slip lead, cut to your length at my bench and finished by hand. If you would rather the collar stayed on the dog and used your own lead, there is a 10mm adjustable slip collar and a 6mm precision version.
Is a slip lead right for your dog?
Honestly, not always. Here is the version I would give you if you messaged me.
| Your dog | Slip lead? | Why |
|---|---|---|
| Walks well, occasional pulling | Yes | Light, fast, and the release does the teaching |
| Backs out of flat collars | Yes | Closes predictably, so escape is much harder |
| In and out of the car, classes, the vet | Yes | On and off in a second with nothing to fasten |
| Pulls hard and constantly | No | Never gives slack, so the signal never arrives. A figure of 8 does more |
| Panics or is reactive on lead | No | Tightening on a frightened dog makes the fear worse |
| Flat-faced breed, or any airway history | No | Neck pressure is the wrong tool entirely. Use a harness |
Three yeses and three noes is about right. Anyone selling you a slip lead as the answer for every dog is selling, not advising.
Five ways people get this wrong
- Wearing it low. The single most common one, and it undoes everything above.
- Holding constant tension. If the lead is always tight, the release never happens and nothing is being communicated.
- Never setting the stopper. Straight out of the packet it is usually in the wrong place for your dog.
- Leaving it on at home. Do not. A slip lead is for a walk, with you on the other end, and nothing else.
- Expecting it to fix pulling. It is a way of talking to your dog, not a brake. If the pulling is the problem, the training is the answer and the lead is just the phone line.
If any of that sounds like your walks, message me. I would far rather spend ten minutes helping you set a stopper than have you decide the whole idea was cruel.
When a slip lead is the wrong tool
Worth stating plainly, because it does not get said often enough by people who make them.
- Dogs that pull constantly and never offer slack
- Dogs that panic on lead, or have real lead reactivity
- Any dog with a history of tracheal or airway trouble
- Brachycephalic breeds, so pugs, bulldogs and French bulldogs, where neck pressure is contraindicated
- Puppies still learning to walk, if they are throwing themselves into the end of the lead
For welfare-led guidance on loose-lead walking, the Dogs Trust loose lead guide and RSPCA training guidance are both a sound starting point.
Why the stopper matters more than the rope
Everyone talks about rope. Almost nobody talks about the stopper, and the stopper is what decides whether a slip lead is kind.
It sets the point at which the loop stops closing. Set well, the lead cannot tighten past snug no matter how hard the moment gets. Set badly, or made from something that binds and sticks, the loop closes further than it should and then fails to open again when it matters.
That is the whole reason I make these by hand. The rope has to run cleanly through its own loop, the whipping has to be smooth enough not to catch, and the stopper has to hold where you put it. Cheap slip leads usually fail on the third one, which is why they end up feeling harsh through no fault of the person holding them.
Fittings vary by product, so rather than promise one metal across everything I make, each product page lists exactly what that piece is built with. Everything is made to order in Oxford, takes two to six working days, and is guaranteed for twelve months.

Frequently asked questions
Are slip leads cruel?
No, but a slip lead used on constant tension is. The tool works on pressure and release: the loop tightens when the dog pulls into it and must open again the instant the dog stops. The information the dog receives is the release, not the tightening. A slip lead that never goes slack has stopped communicating and has become a permanently tight rope around a neck, which is a fair thing to object to. Fitted high on the neck and used with timing, it is neither harsh nor painful.
Are slip leads bad for dogs?
Not when used correctly. A slip lead positioned high on the neck behind the ears, with the stopper set so it cannot close past snug, and used with timing rather than constant pressure, is an effective and humane training tool. The risk comes from incorrect use: constant tension, positioning low over the trachea, or use on dogs that panic. For those dogs a harness or a different setup is more appropriate.
Where should a slip lead sit on a dog's neck?
High on the neck, just behind the ears, not at the base where the neck meets the shoulders. There are two reasons. The trachea sits low on the neck, so the high position avoids it. And high on the neck is the most responsive part of the dog, so the signal is lighter and clearer, whereas at the base of the neck a dog has maximum leverage and will simply lean into the pressure.
How do I stop a slip lead tightening too much?
Set the stopper, the ring or knot that limits how far the loop can close. Position it so that under tension the loop snugs to roughly two fingers of clearance and no further. When you release, the loop should drop back to fully slack on its own. If it keeps closing past comfortable, or does not reopen when you let go, move the stopper. A loop that will not reopen is the single most common fault.
How long should a slip lead be?
Most dogs and handlers suit 120cm to 140cm, which gives enough rope to hold comfortably at your side without slack dragging. Taller handlers, or anyone wanting to wear the lead across the body between uses, tend to prefer 150cm to 180cm. Longer lengths up to around 230cm exist mainly for handlers who want to loop the lead over a shoulder. Length is a handling preference rather than a sizing decision, because the loop adjusts to the dog.
How do I know if a slip lead is working?
Watch the slack, not the dog. On a slip lead that is working, the loop spends most of the walk loose and only closes briefly when your dog moves ahead, then opens again straight away. If the lead is tight for most of the walk, the tool is not doing anything useful regardless of how the walk feels, and the answer is training rather than more pressure.
