Helps Reduce Barking, Chewing & Accidents When You Leave

$49

  • For barking at the door, chewing when alone, and accidents that only happen when you leave.
  • One socket, thirty nights, working on its own. Nothing to feed him, nothing to swallow.
  • Dog pheromones only. A cat in the same house does not react to it.

What is in the box

One plug-in base and one vial per unit. Everything that works is in the vial, not in the base.

How to use it

Plug it into the room where he waits for you — not the hallway. Leave it running day and night. Replace the vial on day thirty even if you can still see liquid.

Where this will not help

A dog who was never house-trained needs training, not a diffuser. Accidents after a food change, a new medication or sudden thirst belong at the vet. A dog who panics — drools, breaks out of crates, injures himself — needs a behaviour professional. And a spot never cleaned with enzyme cleaner is still an invitation.

Shipping and returns

Ships from our US warehouse, arrives in 2–5 business days. Free shipping over the threshold shown at checkout. 30 nights, money back — write to hello@pheroniapets.com and you keep the diffuser.

Safety

Nothing is swallowed and nothing is sedated. Keep the vial out of reach of children and pets. Not a flea, tick or pest-control product.

Full description

He is not spiting you. He is asking whether you are coming back.

The puddle by the front door, always in the same spot. The barking that starts the second the car pulls out. The chewed door frame, and the neighbour who has mentioned it twice now.

A house-trained dog who suddenly is not house-trained is rarely being naughty. He is telling you the house does not feel safe when you are not in it.

What Stillroom does

Helps calm and relax your dog by filling the room with a copy of the scent signal his mother gave her litter in the first days of life. It is the earliest thing a dog ever learns to read as: you are safe, nothing is coming. Dogs keep responding to it for life.

No pills. No drowsiness. Nothing he has to wear or swallow. There is a difference between a calm dog and a drugged one, and this is the first kind.

Where it earns its place

  • Staying alone, and what the flat looks like when you get back
  • Loud noises: fireworks season, thunderstorms, builders next door
  • Visitors, the doorbell, the hallway
  • Indoor accidents that started again after months of none
  • A rescue settling into a new home, or a puppy in the first weeks
  • Crate training that is not going well

Using it

  1. Twist the vial into the base, hand tight. No tools, no batteries, nothing to charge.
  2. Plug it in upright, in the room he waits in while you are out. Never behind the sofa or under a shelf.
  3. Leave it running, including while you are home. The point is that the room is already settled before you leave, not that it settles after you go.
  4. Give it a full month before you judge it. Most people quit on day four.

Where it will not help, honestly

A dog who has never been house-trained needs training, not a scent. A dog who suddenly cannot hold it needs a vet, because that is often a bladder or a kidney, not a mood. And severe separation distress, with drooling, self-injury or escape attempts, belongs with your vet and a behaviourist. This supports the room. It does not replace the work.

Good to know

  • One vial covers roughly one room for about 30 days
  • Silent, no fan, and no scent people notice
  • Two rooms means two diffusers. It does not travel through the house.
  • Going in the car or to the kennel? The Softband collar goes with him.
  • 30 nights or your money back. One vial, one room, one full month.

Made for behavioural comfort. Not a medicine and not a treatment for any condition. Not a flea, tick or pest-control product. Talk to your veterinarian about persistent changes in your pet's behaviour.

Why it works

Three things nobody else tells you.

A dog beside a chewed door frame AI-generated image

The blame

It is a signal, not a character flaw.

Nothing here is about discipline. The behaviour is information, and information can be answered.

The mechanism

A copy of the calm signal.

Synthetic pheromone analogues have been used in veterinary practice for over twenty years. They are a signal, not a sedative.

Thirty nights with a dog AI-generated image

The honest clock

Judge it at thirty nights.

Most people quit on day four because they expected day one. The change usually shows in the second half of the month.

Three steps

Plug it in. Leave it. Decide at thirty.

Choose the room

Where he waits for you, not the hallway. One socket covers that room.

Anatomy

Two parts, one of them does the work.

The diffuser, close up AI-generated image
01

The vial

Everything that works is in here. Thirty days per vial, released evenly — the last millilitres release far less than the first.

02

The base

A gentle warmer, nothing else. No fan, no noise, no bulb to replace. You keep it and refill it.

03

The socket

Plug it in at floor or waist height in the room where the trouble is. Not behind a sofa, not in the hallway.

Honest limits

Where this will not help.

We would rather lose the sale than take it under a false expectation.

  • A dog that stops eating, limps or changes suddenly needs a vet, not a diffuser.
  • A dog who was never taught to be alone needs training. This takes the edge off, it does not teach.
  • Severe panic — drooling, breaking out of crates, self-injury — belongs with a behaviour professional.
  • A spot never cleaned with enzyme cleaner is still an invitation. Clean it first.

The evidence

What the research actually found.

The dog evidence is thinner than the cat evidence.

These are independent studies of dog appeasing pheromone as a category. They were not run on our product, and we do not claim their results as ours. The honest summary: one good study found a clear effect on firework fear, and two careful reviews found the wider evidence weak.

  • Effect found

    Dogs frightened of fireworks showed a significant improvement across several fear behaviours on dog appeasing pheromone.

    Owner-reported scoring, and a small group by modern standards.

    Sheppard and Mills, Veterinary Record, 2003

  • Weak evidence

    Across eight controlled studies, the evidence for dog appeasing pheromone in adult dogs was judged weak, with little carry-over once it stopped.

    Only four of the eight were randomised. The authors call it harmless and possibly useful, not proven.

    Wong and Govendir, Veterinary Evidence, 2021

  • No effect

    Dogs in long-term kennelling showed no significant change in stress behaviour on dog appeasing pheromone.

    A kennel is a hard case. It tells you where the ceiling is.

    Grigg and Piehler, Veterinary Record Open, 2015

We would rather you know that before you buy than after. Thirty days to decide either way.

Every link below goes to the published paper, not to a summary we wrote.

Before you buy

Six questions we get every week.

How long until I see a change?

Most of it happens in the second half of the first month. Watch how he settles when you pick up the keys before you count incidents. That is why the guarantee runs 30 nights.

Is it safe around children and cats?

Nothing is swallowed and nothing is sedated. Pheromones are species specific — the version for dogs carries no message a cat or a person can read. Keep the vial itself out of reach.

When does it arrive?

Ships from our US warehouse and arrives in 2–5 business days. We ship within one business day; if we ever miss that, we write to you and you can cancel.

What if it does not help?

Write to hello@pheroniapets.com within 30 nights and we refund the whole order. You keep the device — sending a used plug-in back across the country helps nobody. One claim per household.

Does it help with fireworks and thunder?

Start it days before, not an hour before. For the night itself the collar is the better tool, because it goes where he goes — under the bed, into the bathroom, wherever he decides is safe.

Can I use it with a cat in the house?

Yes. Use the dog version for him and the cat version for her, and give each of them a room. The two can run in the same home.

All questions

Goes with it

It stays in the room. For the car, the kennel and the clinic, that is the collar.
