How it works
How does it actually work?+
It's a 100% natural onyx stone that clips onto your dog's collar or harness. Onyx has been used for centuries as one of the most grounding stones there is — worn close to your dog, it eases the tension the barking comes from, so instead of firing off instantly your dog gets the space to take a step back before reacting. No shocks, no chemicals, nothing enters their body.
How can a stone possibly change my dog's barking?+
We understand the scepticism — it does sound surprising at first. Grounding stones like onyx have been used for centuries to steady the nerves. And unlike a spray or a shock collar, it doesn't wait for the barking to start: it's on your dog while they wear it, working on the tension the barking comes out of rather than punishing the noise after. That's why 84% of surveyed owners saw less barking within 7 days.
How fast will I see a difference?+
Many owners notice a difference within the first minutes to the first few days. For deeper, long-standing issues (trauma, severe reactivity), it builds more gradually over a couple of weeks of consistent wear. The key is keeping it on through the moments that set them off, so a steadier baseline becomes their new normal.
Does it suppress my dog's natural instinct to bark?+
Not at all. Dogs are meant to bark — it's how they communicate. This doesn't silence your dog or dull their instincts. It works only on the excessive, over-the-top barking that comes from a nervous system on high alert. Their normal, happy "someone's at the door" bark stays completely intact.
Will it work for my dog?
Will it work for a reactive dog?+
Yes — reactive dogs are exactly what it's made for. Reactivity comes from a nervous system stuck on high alert, so your dog fires off before they can think. The onyx eases that underlying tension, so they meet their triggers from a steadier place and react less. It works best worn consistently, and pairs really well with any lead work you're already doing.
My dog is on edge rather than barky — will it still help?+
Absolutely. Barking is just the most visible sign of a dog on high alert — what the onyx really does is ease the underlying tension and help your dog feel steadier in themselves. For a nervous dog who simply needs to feel less on edge, it's a lovely fit, whether or not barking is the main issue.
Does it help with fireworks, storms or loud noises?+
Yes — noise reactivity comes from that same spike of tension in a dog already on alert. Worn on the collar, the onyx helps your dog cope better in those moments. Honest tip: for really intense firework nights, it works best alongside a calm, cosy safe space rather than as a magic switch — but it genuinely takes the edge off.
Will it work for a rescue dog with a difficult past?+
It can help a lot. A rescue's reactivity often comes from a nervous system left on high alert by past trauma — and that underlying tension is exactly what the onyx eases. For deep trauma-based cases, it works best alongside gentle training and patience: the steadier baseline it builds makes that work land far better.
My dog barks at other dogs on walks — will it help?+
Yes, that's a very common use. On-lead reactivity comes from a spike of tension your dog can't regulate in the moment. The onyx eases that, so they meet those encounters from a steadier place and react less. It works best worn consistently (not just on walks) so a calmer baseline sets in.
Does it work for aggression?+
We're always honest: it isn't a cure for genuine aggression, and serious cases should be worked on with a qualified behaviourist. What it does do is ease the underlying tension that often fuels reactive behaviour — so it's a helpful support alongside proper training, not a replacement for it.
I have several dogs — does each need their own?+
Yes, each dog needs their own pendant — they work independently. If you've got a few barkers, calming the ones that tend to set the others off often settles the whole pack. With multiple dogs, the pack is the obvious choice — buy 2, get 1 free.
Fitting & wearing
I have a very small dog — will it be too big or heavy?+
Not at all. The pendant is a single 16mm stone — about the size of a marble, light and comfortable on any dog, even the smallest. It simply rests on the collar, with nothing heavy on their neck.
How does it attach? Does my dog need a collar?+
It clips onto any collar or harness in seconds — 3 attachment rings are included for the perfect fit, plus a short guide with tips. No collar? No problem — it attaches just as easily to a harness. It just needs to stay close to your dog.
My dog keeps trying to chew it — what do I do?+
Use the smallest attachment ring so it clips higher and tighter against the collar, sitting snug instead of dangling where they can grab it. Once it's not swinging like a toy, most dogs lose interest. Letting them investigate it for a day helps too. Still going for it? Email us at

Can it be left on all the time, or removed at night?+
Whatever suits your dog. It's water-resistant and safe to leave on, so you can keep it on through the moments that set them off — or take it off at night, that's fine too. The one thing worth knowing: the hours it's off are the only ones it can't help with, so for a dog anxious at night, keeping it on carries the calm through.
Safety & material
Is it safe? Is this like a shock collar?+
It's the complete opposite of a shock collar. There are no shocks, no sprays, nothing that hurts or scares your dog. Shock and spray collars work through fear and pain, which only winds an already-stressed dog up more. This simply helps your dog feel steadier, so they settle because they genuinely feel better. There's nothing kinder.
What is it made of?+
100% natural black onyx — a real stone, nothing synthetic, no coating, no chemicals. Nothing enters your dog's body; it simply rests on the collar and works close to them.
Is this real onyx, or just obsidian / dyed stone?+
Good eye — pure, high-grade black onyx is genuinely rare. Ours is selected AAA-grade natural black onyx, carefully sourced — not the dyed or heat-treated stone common elsewhere (which loses most of its grounding strength), and not obsidian (a volcanic glass with a different structure). That grade is the whole reason it works when a cheap bead doesn't.
The charger & care cloth
Do I need the Stone Charger?+
No — the stone doesn't stop working, and you won't need the charger when starting out. Over several months of daily wear, a natural stone gradually loses a little grounding power. The charger resets it to full strength and amplifies the effect. It's optional and only useful later on — the pendant alone is all you need to start.
Do I need the Care Cloth?+
No, it's not needed to get results. But worn every day, the onyx gradually picks up dust and oils that can dull its power. The cloth is made specifically for the stone — it cleans it gently and safely (a regular cloth can scratch it), keeping the effect strong. A nice way to protect results long-term, but totally optional.
If my dog's calm has faded, is the product faulty?+
Almost never. When the effect fades after a while, it's usually just that the stone has run down or picked up buildup — not a fault. Recharging or cleaning it brings the calm right back, often stronger than before. If you're ever unsure, just reach out and we'll help.
Ordering, shipping & guarantee
Is there a money-back guarantee?+
Yes — every order is covered by a 30-day money-back guarantee. Clip it on, give it a proper try, and if you're not seeing a difference in your dog, just reach out for a full refund. The only real risk is one more month of barking.
Do you ship to my country? How much is shipping?+
