What does Boelou help with?
From mother nature to NeuroScent™
From an instinct every animal already has to a technology that puts it to smart use. Here's the story in 4 steps:
A safety signal
After giving birth, a mother dog releases a signal that reassures her puppies: you're safe. That signal keeps working for the rest of their lives, even into adulthood.
Continuous signal
The diffuser releases a safe, recreated version of this signal into the air all day long, completely unnoticed.
The organ of Jacobson
Your dog doesn't smell this signal like a regular scent. It's picked up by the organ of Jacobson, a separate organ at the back of the nose, apart from the normal sense of smell.
A calmer brain
From that organ, the signal travels directly to the part of the brain that regulates emotions. As a result, your dog will show calmer behavior within a short time. We call this entire process NeuroScent™.
How to use the diffuser
Set up in under a minute, the diffuser takes care of the rest.
1
Choose an outlet
In the room where your dog spends the most time
2
Click in the refill
Twist until it's securely in place
3
Turn on the diffuser
Let it run 3 to 8 hours a day for the best results
Note!
Keep the head facing up, never on its side or upside down, to prevent leaking.

I sat on this decision forever, but so glad I acted, Luna reacts to things with so much more composure. Firework season was always mayhem, such an improvement now. Grabbed another one for upstairs.
Our vet recommended trying this, and Vos and Sara don't tremble at minor sounds anymore. Totally sold.
My colleague swore by it and what a good call that was — the endless pacing is over. Vacuum time was always war, now he sleeps right through it. It's earned its spot.
I wasn't convinced it would work, but Loki is comfortable enough to lie still and chill again. The groomer used to be a nightmare, things have improved a lot. Extremely satisfied.
Seriously the best purchase of this year. Every evening we had whining at bedtime and that's just gone now. Smells subtle, nothing intrusive. Just look at that content face in the photo.
Spotted this on Instagram and ordered right away, and my furry friend has found their calm again. If your dog has anxiety, get this.
An Instagram post led me to this purchase, and our little pup no longer vanishes when stressed. One refill keeps going forever. Couldn't be more pleased.
We had absolutely no idea what else to try, and Diesel has stopped disappearing from sight. Takes a few days to really kick in. Glad I went for it.
The price made me think twice, but I went ahead, and our little one is way more relaxed now. Great value for the money in my opinion. Happy I took the chance.
I figured this was an expensive mistake, but our dog is no longer in a constant state of alert. Grooming used to end in tears (mine), smooth as butter now. Positioned in the hall, the whole house benefits. If your dog is wound up, get this.
Having exhausted so many other options, I figured why not try this too, and no more restless pacing. The move messed him up, this brought him back to normal. This is permanently plugged in now.
Best tip I ever got from a friend. The vacuum cleaner used to be a war zone and now he just lies there unbothered. Simple little device, huge difference. Added a photo.
I was swayed by all the great feedback, and our pooch has become a champion sleeper at night. He used to bolt from the vacuum, now he yawns at it. Each refill is surprisingly durable. Any worried dog owner should try this.
A friend's success story brought me here, and there's way less barking now. Vacuum day was always a nightmare, smooth as silk now. Nailed it — this was the solution.
The raving reviews got me to finally buy, and the stressed panting has completely ended. The car was his worst enemy, now he loves the back seat. Just find a plug point and you're golden. Leaving it on indefinitely.
A random buy that became my best purchase — Vos can finally relax. Worth every single cent.
Price-wise I wasn't sure, but I pulled the trigger, and Suki sleeps without interruption now. He stays composed when we head out. No instructions needed, just plug it in. Value for money is excellent.
My friend couldn't stop talking about it so I tried, and the restless roaming has ended. The veterinarian's office was pure stress, totally manageable now. For stressed-out dogs, this is the answer.
I'd been looking for something like this for months, and the vibe at home has totally changed. Glad I waited it out. You won't regret it, promise.
Reading all the happy customers made me order, and Storm has developed a proper sleep routine. If your pup has anxiety, try this.
Plugged it in without expectations and let it run, and Rakker can finally relax and be at ease again. I can't praise this enough.
Got it set up and just let it work its magic, and Luna no more anxiety-driven heavy breathing. Here to stay for good.
I almost didn't order because of the cost, but I did, and the behavioral change is unmistakable. Our move was really hard on him, this was a lifesaver. Scent-wise, it's barely detectable to humans. Couldn't go back to life without it.
The vet mentioned this could work, and the transformation in behavior is clear. Every loud sound used to startle him, he's unfazed now. Results aren't instant but they're real. To sum it up: fantastic.
To be fair, I didn't think much would change, but the pre-bedtime whining has ceased. Any bang outside would set him off, those days are over. Took some patience, but the results came. Ecstatic about this purchase.
I ordered on a whim of curiosity, and Fien isn't as wound up during the day. Road trips were impossible, he rides like a champ now. Couldn't give it anything less than five.
Behind closed doors I didn't believe a word, but bark episodes are much rarer. So easy even I managed it. Wish I hadn't waited so long.
Decent, but Guusje loud sounds still trigger a startle.
So many pet owners loved it, I figured I should try too, and our dog doesn't cower away anymore. A lasting addition.
Used it for a few weeks, but the big difference never came for us.
This was my 'nothing to lose' order, and our little hound sleeps through even the noisiest of nights. The vacuum could run right next to him and nothing happens. You literally just plug it in. My verdict: top-notch.
One of my coworkers was enthusiastic about it and trusting their judgment paid off big — Bink can finally relax. I'd call this a smart spend.
Internally I had zero faith in this thing, but the trembling has retreated to barely noticeable. Thunder meant instant couch-diving, he doesn't flinch now. It manages itself perfectly. A staple in our house now.
Nice idea, but I barely see a difference with Storm.
We were drowning in frustration, and the end-of-day whining has ceased. He stayed on his spot during the last thunderstorm, amazing. Takes about five seconds to install, if that. I'd swear by this now.
I'm here because of a friend's recommendation, and our pup doesn't shrink away anymore. No more separation anxiety episodes when we leave. Recommending this until I run out of friends to tell.
It was the vet who convinced us to try this, and Nova has settled into calm daytime behavior. The move left him shaken, this gave him his confidence back. From disbelief to total trust.
A spur-of-the-moment decision I'd make again in a heartbeat — our fur child has become the calm one in the house. We can finally take drives without stress. It lives up to claims, with some patience.
I was hoping for more. At best it helps just a tiny bit in our house.
Frequently asked questions
How exactly does the diffuser work?+
Dogs and cats communicate not only through sound, but also through scent signals. Right after birth, a mother dog releases a scent that tells her puppies: you're safe. That signal keeps working for the rest of their lives. This scent has been recreated by experts. Not medication or a supplement, but an artificial copy of something that already exists in nature. The diffuser releases this signal into the air, unnoticeably, throughout the day.
What makes Boelou different?+
Thanks to the expertise behind Boelou, we know exactly how your dog or cat picks up this signal best: at what dosage, with what release, and via which pathway to the brain. Not through the regular sense of smell, but through Jacobson's organ. A separate organ at the back of the nose with a direct connection to the calming part of the brain. We call this process NeuroScent™. Thanks to this expertise, we stand 100% behind the effectiveness of our product.
Is it safe for my pet?+
Yes. The liquid contains no medication and no chemical sedatives. It's a recreated version (analogue) of a scent (pheromone) that dogs and cats naturally produce themselves. Odorless to humans, safe around children and other pets. We recommend running the diffuser 3 to 8 hours a day for the best results; if your pet shows visible separation anxiety, the diffuser may also stay on all day.
Does it work for both dogs and cats?+
Yes, for both! But not with the same diffuser. Dogs and cats respond differently to the signal, so there's a NeuroScent™ Diffuser specifically for dogs and a separate one for cats, each with its own dosage and release.
How soon will I notice a difference?+
Most pet parents notice a visibly calmer pet within one to two weeks. But keep in mind: every animal is different, so feel free to give it some time.
How long does a refill last?+
At the recommended use of 3 hours a day, a refill lasts approximately 30 days, in a room up to 60m². If you run the diffuser more hours a day (up to the full day for visible separation anxiety), the refill will run out sooner based on usage.
What if it doesn't work for my pet?+
Get in touch with our customer service and we'll find the best solution together. Try Boelou for 30 days — there's always a solution that fits.
What type of plug does the diffuser have?+
The diffuser has a fixed European plug (type C, also known as the Europlug).
