Drug-free · 60 days per collar
Most trainers charge $150 a session. CollarZen is $49.95 and works for 60 days.

How it works
His own body heat is the switch.
The pheromone blend sits in the TPR. His warmth releases it, slowly, right below his nose — which is where it needs to be, because that's how a dog reads the room.
Nothing to give him. Nothing to remember. It's working at 3 a.m. when the storm rolls in and you're asleep.
- 01Body heat activates itNo batteries, no spray, no plug. He powers it just by wearing it.
- 02Released at nose levelWhere scent actually lands for a dog — not across the room in a wall socket.
- 03The panic loses its volumeIt works on the stress response, not on his energy. He stays entirely himself.
When it matters
You already know which one is yours.
Anxiety doesn't show up as anxiety. It shows up as a chewed door frame, a neighbour's complaint, a dog who won't get in the car.
The part nobody mentions
Two months, not one.
Almost every calming collar on the shelf quits at 30 days. CollarZen runs 60. Over a year that's three collars instead of six — half the cost per day, and half the number of times you realise the old one stopped working a week ago.
You've probably tried some of these
Where a collar wins, and where it doesn't.
An honest look. Treats and vests do real work for some dogs — they just ask something of you every single time.

What to expect, honestly
This is not an on-off switch.
Some dogs soften in the first few days. Others take two or three weeks before the baseline really moves. Both are normal, and neither means it isn't working.
- Day 1 It goes on and starts releasing. Most dogs stop noticing the collar within a few hours.
- Week 1 The first thing owners usually notice is a shorter reaction — he still hears the thunder, but he settles again faster.
- Week 2–3 Fewer accidents. Less scratching at the door. The house comes home in one piece more often than not.
- Month 1 For many dogs this is where the baseline shifts — less on edge generally, not just during the storm.
- Month 2 The collar is spent. Swap it before the old one runs out, not after — the gap is when the old habits come back.
- Month 3+ Calm stops being an event and starts being how he is. That is the whole point.
Individual results vary. This timeline describes what owners commonly report and is not a guarantee of outcome for any particular dog.
Fit
One size, genuinely.
62 cm of adjustable TPR strap — about 24.4 inches. Buckle it with two fingers of room underneath and trim the tail. That fits necks up to roughly 21 inches, which covers most dogs from a chihuahua to a labrador.
The risk is ours
Thirty days. Then decide.
Put it on him and watch. If the storms are still the same, if the empty house still ends in a chewed door frame, write to us inside 30 days and we refund the order in full.
You don't need to send back an unused collar. You don't need to argue your case or fill in a form. You wrote to us, that's enough.
Last look at the kits
Two collars gets you three.
Same guarantee either way: thirty days, full refund, no argument.

Still unsure? support@neekozen.com
Is this a sedative?
No. There's no drug and no sedative in it. Your dog stays fully alert and fully himself — the collar works on the stress response, not on his energy or personality.
How long does one collar last?
Sixty days from the day you put it on. Most calming collars run 30, so one CollarZen covers what usually takes two.
How fast will I see a difference?
The collar starts releasing within about an hour. What you notice, and when, varies a lot by dog. Some owners see the edge come off in the first few days; for others it's two or three weeks before the baseline really shifts. If nothing changes in 30 days, send it back.
Will it fit my dog?
The strap is 62 cm — about 24.4 inches — and adjustable. Buckle it with room for two fingers underneath, then trim the excess. That fits necks up to roughly 21 inches, so most dogs from a chihuahua to a labrador. If yours is a giant breed, measure his neck before you order.
Can he wear it with his regular collar?
Yes. Wear it alongside his everyday collar or harness. It's thin and light enough that most dogs stop noticing it within a day.
What happens in the rain, or at bath time?
Nothing. It's waterproof TPR — getting it wet doesn't dilute it and doesn't shorten the 60 days.
I've already tried treats and a vest. Why would this be different?
Honestly, it might not be — no calming product works for every dog. What's different is the delivery: nothing to give him on schedule, nothing to put on before a storm you didn't see coming, and it keeps working while you're out of the house. That's the gap treats and vests leave.
My dog is aggressive. Will this fix it?
Don't buy it for that. Aggression and severe distress need a veterinarian or a qualified behaviorist, not a wellness product. CollarZen is for anxiety — the storms, the empty house, the car.
What if it doesn't work?
Return it within 30 days and we refund it in full. You don't need to send back an unused collar or argue your case.
