Questions & Answers

11 Customer Questions


Can this diffuser be used in or near a room where a cat calming diffuser is already in use?

Answer by ChewyNov 03, 2020
While the pheromones in ThunderEase for Dogs and ThunderEase for Cats is completely different, there is no issue with using both in a multi-pet household. Because the pheromones are different, you will need to purchase more than one diffuser or spray for dogs and cats, but feel free to set up both for calming for all your pets.

Do you carry the diffuser unit?

Answer by ChewyJun 28, 2018
The ThunderEase Dog Calming Diffuser Kit is available for purchase.

Will this help with anxiety brought on by a new dog in the house?

Answer by ChewyNov 16, 2018

What does this smell like?

Answer by ChewyApr 25, 2023

We adopted a dog that had severe anxiety of storms. It was so bad that he torn down my bedroom blinds and knocked over a floor mirror when we weren’t home. We would go out for a walk with our other dog, and he would stop and refuse to go any further because he sensed a storm coming in(even though it was sunny). We had to go immediately home. During a storm with thunder he was a trembling scared dog and he hid out in my pantry (no windows). We purchased the room outlet diffuser and the collar. Wow! This made an amazing difference. A storm with thunder; no problem. He was 80% his normal self. He still has some walk anxiety, but is not quite as bad. He trots along without a care for the most part. It changed our life!

Best Advice From Our Vet!!!

This must be the best advice I ever had from our vet and we completely love her!!! Our vet has known our chihuahuas for 11 years. My youngest chihuahua is 3 years

This must be the best advice I ever had from our vet and we completely love her!!! Our vet has known our chihuahuas for 11 years. My youngest chihuahua is 3 years old and he gets anxious but takes it out by playing with items he knows are not his and also tends to use the facilities in the house when stressed. Our vet said to try this Thunderease, also known as Adaptil. It is a plug-in pheromone that sends scent into the air that only doggies can smell and it helps to keep them calm. This is so true after so many things tried with our chihuahuas. He now just chills out during the day, takes naps and waits til we get home to go outside. I signed up for auto-ship so I will never run out. It says that it lasts for a month, and it surely does last the entire month! So no worries about running out early. It is released slowly. Again, the best advice from our vet for doggie anxiety. Thanks!!!

This definitely helps our pup taffy relax and stay calm when home alone. She used to have extreme anxiety and would bark when we leave for outings. Feeling bad for our pup and trying to find solutions we came across this item and I can honestly say this helps our taffy relax, and feel calm. Now she does still bark for a short time but ultimately calms down after about 5-10 min of being alone. I would definitely recommend you try this product if you also have a dog that has extreme anxiety.

I brought in a foster that I later adopted. The first few weeks were tense between the two dogs and I plugged this in and like magic everyone was chill. I did it for three months. It was noticeable difference when the first one ran out- tension started again. I feed them in separate rooms and kept toys put away but there was this “I see you and you don’t belong here” mentality that completely went away with these. I was able to stop using them after three months.

We thought my puppy had terrible food allergies. He was itchy all over, scratching and chewing himself raw. His mouth and face were particularly affected and sometimes he would scratch so hard he'd injure his face/eyes/ears. We have every cone and recovery suit the internet sells to try and keep him from scratching himself. It was so sad to see a 7 month old puppy so itchy he's crying. Anyway, turns out this was the cause. I unplugged the diffuser, opened all the windows, turned all the fans on, washed every blanket/pillow/piece of clothing and gave the puppy a very thorough bath and he began improving immediately. So if your dog is experiencing allergy symptoms and you use this, consider this as a potential allergen!

A neighbor told me about these and I'll admit, I was skeptical. I just adopted a dog that hates his kennel and I've been trying to figure out what to do to help him. I tried these and the affect was INSTANT!! He stopped whining and we're even getting to a point that he goes willingly into his bed. But was it just me? All in my head? Nope! I recommended them to a friend for her cat (the cat version of course) and her pet's reaction was instant as well! So glad I found these! I'm a believer!

I have an elderly Boston Terrier, he's 12. He had a very bad blood panel in October indicating possible kidney failure. After changing his diet, his kidney levels were in the higher end of normal range. I was assuming his sudden indoor accidents were either kidney or age related but thought I'd try the diffusers just to see. It is now March and he hasn't peed on the floor since right before Christmas! These things work!

Even if you have one dog tis is a great product for stress. Particularly during fireworks season and for any stressful loud event your dog must endure. I breed Border Collies and train dogs and use it in our kennel as a go to for fireworks, thunderstorms or any loud events. All Adaptil products in this line are great. They make a spray Adaptil that I carry in my go bag for the dogs. It really works.

Brings my dog out from hiding

Our Chihuahua is a rescue and came us very scared and hiding behind the toilet. My vet recommended these and I put 3 of them around the first floor of our home

Our Chihuahua is a rescue and came us very scared and hiding behind the toilet. My vet recommended these and I put 3 of them around the first floor of our home. They have made a huge difference. My dog is much more social and coming out to socialize with us and our other dogs. If they run out, he goes back into hiding.
