The doorbell used to set off ten minutes of barking. By the second week he still got up to look, but he came back and lay down on his own.
I work outside the house four days a week and I was coming home to chewed door frames. The damage stopped and he sleeps in his bed now.
We adopted her in March and she spent the first month under the bed. It is the thing that changed the week we started it.
Open. Fasten. Relax.
Three steps, about a minute, and then you can forget it is there.
Open the pouch
The collar stays sealed until you need it. Body heat is what activates it, so nothing starts until it is on your pet.
Fasten it and trim
Fit it around the neck with room for two fingers underneath, snug enough to touch the skin. Cut off the excess strap and throw it away.
Let it work
It releases steadily for up to 30 days, through walks, sleep and the moments that set your pet off. Take it off only for baths and swimming.
Three houses, three problems
He stopped guarding the front window
A reactive rescue and a street full of delivery vans.
Nine hours alone, nothing chewed
What the camera recorded before and after the switch.
First fireworks she did not hide from
A pet that used to disappear for two days.

Most problem behaviour is, first, a stress problem.
I see anxious dogs and cats every week - the barking, the chewing, the marking indoors. Pheromone support is where I start, because it lowers the baseline enough that training and routine finally have something to work with. It is not a sedative and it is not a cure, but for most households it is the cheapest thing worth trying first.

Customer Reviews
Calmer by the second week
We adopted a two-year-old who paced the hallway every evening and could not settle. The pacing did not vanish overnight, but by the second week he was lying down on his own instead of circling until we went to bed.
No more marking by the front door
A new cat moved in next door and ours started marking indoors within a week. Cleaning did nothing because the problem was not the smell, it was the stress. There were two accidents in the first ten days and none since.
Storms are survivable now
Every storm used to mean a shaking dog wedged behind the toilet for hours. She still hides when the thunder starts. The difference is that she comes out afterwards instead of staying there half the night.
Both cats stopped the standoffs
Two cats, one hallway, endless posturing at the doorway. Three weeks in they are not friends exactly, but they pass each other without the growling.
Honest review: give it the full month
I nearly returned this at day ten because I saw nothing at all. The change was gradual enough that my partner noticed before I did. It is not instant and anyone telling you otherwise is selling something.
