Sophie settles when I leave
My miniature poodle Sophie used to cry, pace and scratch at the door whenever I left. Since adding PHERALO to her routine, she settles much faster and our departures feel calmer for both of us.
Fewer accidents for Toto
Toto would pee by the front door almost every time we left him alone. After making PHERALO part of his daily routine, the accidents became far less frequent and he looks much more relaxed when we return.
Milo rests on his own
Milo, our toy poodle, followed us from room to room and barked the moment he was left alone. With PHERALO running consistently, he is more comfortable resting by himself and our home feels peaceful again.
A calmer welcome for visitors
Doorbells and visitors used to trigger nonstop pacing. Now our dog settles much faster and can stay comfortably in the room with us.
Simple from the first day
Setup took less than a minute and the diffuser fits naturally into our home. It has become an effortless part of our dog’s daily routine.
Alone time feels easier
Our rescue dog is noticeably more settled when we leave the room. We love having a gentle, drug-free option we can keep running every day.
A quieter evening routine
The barking and restless pacing in the evening have reduced, and our dog now curls up beside us instead of wandering from room to room.
Perfect for our busy home
Between children, visitors and everyday noise, our dog struggled to relax. PHERALO helps make the living room feel like his safe, familiar place.
Refills make consistency easy
The refill routine is straightforward and helps us stay consistent. Our dog responds best when the environment stays familiar, so this works well for us.
Would recommend to dog parents
PHERALO looks clean, has no noticeable odor and simply works in the background. It is one of the easiest improvements we have made for our dog.

Helpful answers
Frequently Asked Questions
Everything you need to start and maintain your PHERALO routine with confidence.
What are the ingredients?
PHERALO uses a dedicated calming diffuser refill designed for dog homes. Review the product label for the complete ingredient list and safety information, and use only matching PHERALO refills with the diffuser.
How long will it take to notice a change?
Every dog is different. Keep the diffuser running continuously and give your dog time to become familiar with the routine. Some households notice early changes sooner, while others need several weeks of consistent use.
Where should I use the diffuser?
Place it upright in an open wall outlet in the room where your dog spends the most time. Do not cover it or hide it behind furniture, and follow the clearance guidance included with the product.
Is a light scent normal?
A faint product scent may be noticeable close to the diffuser. If you notice a strong or unusual odor, excess heat or damage, unplug it and contact PHERALO support before using it again.
Should I unplug the diffuser at night?
For a continuous routine, keep the diffuser plugged in day and night as directed. Always keep it upright and follow the safety instructions supplied with your PHERALO kit.
How often should I replace the refill?
Each refill is designed for approximately 30 days of continuous use. Replace it when empty, and consider a subscription if you want matching refills delivered automatically.
