How does ThunderShirt work?
Like swaddling an infant, ThunderShirt applies a gentle, constant pressure to your dog’s torso. Research suggests that this type of pressure can release a calming hormone like oxytocin or endorphins (there is a reason we love hugs!)
How long can I leave ThunderShirt on my pet?
ThunderShirt is safe to leave on for extended periods of time depending on the issue. We recommend removing ThunderShirt every one to two hours the first few times.
How do I clean ThunderShirt?
ThunderShirt may be washed in a regular cycle using regular laundry detergent and cold water. Hang to dry.

- Reviewed in the United States on July 19, 2017Color: BlueSize: lVerified PurchaseThis product is nothing short of amazing. I adopted a 1+ year old ridgeback who turned into a reactive, protective Terminator within weeks of bringing him home--and this is the story about how the Thundershirt saved us.
My sweet pup had spent almost 8 months at a shelter in a cage and no one wanted him because he seemed too hyper. I took one look at this handsome, muscular, athletic young lad and knew I could give him lots of exercise and attention and that I had to get him out of that cage. Home we went. He loved the car and walks and daycare and fetch and everything was new and awesome! And he was suddenly eating amazing raw food and sleeping on a bed for the first time in his life and came to know that his mommy was never ever going to hurt or leave him. Life was grand.
Then....About two months into our new life together, the ridgie alpha maleness, high prey drive and reactivity kicked in, and suddenly everyone and everything was a threat to his precious mommy. He would pace and pant in the car and whine at engine noises from cars around us; he would growl and lunge at any dogs who got near us on a leash; and God forbid anyone step out of an elevator or around a corner too close to me. My sweet ridgie rescue became the most committed personal bodyguard on earth, which is kinda awesome but not practical most days. So we started obedience training, but it was clearly going to take a ton of raw treats, time and money to curb this behavior. We were stressed out.
Enter the Thundershirt. I bought it on a whim to see if it would help with the car anxiety. After a few seconds of staring at the instructions and fumbling with it, I got it on him. He had been racing around the living room like a maniac trying to murder his faborite rope toy (which is typical puppy behavior and hilarious to watch), and the second I put the shirt on him, he totally chilled out and almost immediately fell into a sweet sleep. He looked soooo chillaxed. I even took a walk to the front door and knocked on it to see if he would come racing over and barking like usual. Nothing. He wandered over to investigate, but was silent and calm. Interesting. Maybe this thing really worked!!! After about 20 minutes, I decided to throw all caution to the wind and take him on a walk during peak doggie time in our neighborhood. Scary thought.
I slipped his Roughwear harness (also blue--he looked very stylish) over the Thundershirt, opened the door and out we went. I could not believe what wasn't happening. No pulling. No reactivity. A bird landed on the ground in front of him and he just looked at it. Two dogs passed us within 15 feet and WW3 did not ensue. Previously, that would have resulted in a snarling, barking confrontation. This time, he stopped and looked at them and tensed a bit but did nothing else. I was stunned. He even took a poo not too far away from another pup, something that never would have been possible before.
When we got home, I took the shirt off and he immediately went back to sleep. The next morning, I really pushed the envelope by sleeping in past 5:00 am (which was when I would typically have to take him out in order to avoid all the "threats" around us) and took him out during peak doggie time. He sauntered around the corner, and we ran smack dab into a male lab. Nothing happened. The lab even gave a low growl and my ridgie stopped and waited for him to pass. I could not believe my eyes. Then a loud engine popped around the corner (we live in an urban area) and my little man tensed up but didn't freak out like usual.
The Thundershirt works, people. If it can turn my large ridgie Terminator into a docile keeper of the peace, surely it can help with any anxiety your pup might be facing. I will only use it when we walk in public or ride in the car, because his playful, energetic personality is a big part of him and I don't want to stifle that. But wow, what a difference this product has made for us. Bravo, Thundershirt. You nailed it.
- Reviewed in the United States on January 1, 2025Color: BlueSize: SmallVerified PurchaseSo my dog is very anxious with loud noises. He’s a rescue with a very strong attachment to me. Fireworks were always an issue around the 4th of July and New Year’s Eve. Well, it’s New Year’s Eve and we’ve got a baby now and somehow, this thunder shirt is definitely easing some anxiety for my dog. He’s not freaking out as much which is keeping the baby asleep! It’s a win in my book. It’s a little confusing to put on but just be patient and follow diagrams! Size wise, it’s working well! It’s stretchy as promised! It will hold up well over time, it’s been in the wash and the durability of the Velcro hasn’t gone down!
- Reviewed in the United States on February 7, 2025Color: CamoSize: SmallVerified PurchaseThis product surprised me honestly. The quality was great, and we washed this vest multiple times with no issues and it was easily done, just making sure the Velcro is attached prior to being tossed in the washer. Our puppy grew out of his like we knew he would, he is a beagle and fit the small fine at first but now would require a medium. So overall runs true to size with their chart. Our puppy normally hated wearing things even his collar but seemed to be fine after a few mins and seemed to be comfortable when wearing it. He could not slip out of it easily and it remained on him until we removed it. He has major separation anxiety and this seemed to help. It did not completely rid him of this, but made him slightly more calm. We put a blanket with our scent on it and this on him when he needed to be crated and it helped.

Telma CasacaReviewed in Italy on May 30, 2022
5.0 out of 5 stars Perfetto! Il mio cane è diventato molto più calmo durante i fuochi d'artificio
Color: PinkSize: MediumVerified PurchaseHo comprato la Thundershirt per il mio cane che ha molta paura dei fuochi d'artificio (Ho comprato la taglia M e il mio cane pesa circa 15 kg). Avevo già provato altre cose, come le pillole calmanti e non ha funzionato. Non ero molto sicuro della Thundershirt, ma sono rimasto sorpreso! Le prime due volte non sembrava funzionare, ma dopo aver visto un video su youtube mi sono accorto che non avevo stretto abbastanza la Thundershirt. Quando ho iniziato a stringere correttamente la thundershirt la differenza era molto grande! Il mio cane trema molto durante i fuochi d'artificio, il suo cuore batte molto velocemente e diventa molto irrequieto. Con la Thundershirt è subito più calma. Accetta persino di mangiare il suo paté e va a letto per fare un pisolino. Non avrei mai immaginato che fosse possibile <3
Dopo un mese di utilizzo di Thundershirt, il mio parere è molto positivo e lo consiglio a tutti. Vivo a Malta e ci sono molti fuochi d'artificio qui durante l'estate (quasi tutti i giorni)... È stato molto stressante per il mio cane e per noi. In effetti, ero molto felice! Ecco perché ho consigliato oggi Thundershirt al più grande gruppo di animali qui a Malta su Facebook, poiché so che anche molti cani qui soffrono come il mio con la paura dei fuochi d'artificio. Quindi se ricevi molti ordini da Malta, questo è il motivo, ho condiviso il tuo prodotto. Consiglio vivamente! =)
P.S - scusa se l'italiano non è il migliore perché ho usato l'aiuto del traduttore di google =)

1.0 out of 5 stars Didn't work for my dog
Color: BlueSize: XX-SmallVerified PurchaseMy dog suffers from separation anxiety and his main problem is crying in his crate even if left for 10 minutes. He's perfectly happy in his crate if I'm around, but when I leave the room he whines and howls and barks. I hoped the thunder shirt would help but there has been no change whatsoever in his behaviour unfortunately.

5.0 out of 5 stars Thundershirts work! A Doubter is Flipped
Color: PinkSize: X-SmallVerified PurchaseOur family has a Pom-Chi whose nerve condition is horrendous. She will get riled at any kind of vibration - a truck driving by the house, a doorbell ringing, mail coming through the slot, other dogs near hear when she is out for a walk, fireworks, and thunder and lightning.
We were actually contemplating finding her a new home - until I learned about Thundershirts on a TV Ad. I went to my Amazon account, and found them, and found an Extra Small for the Pom-Chi.
We put it on her, in a non-thunderstorm condition. It was like magic! You could note her immediate calm - as a matter of fact, we examined the Thundershirt afterwards to see if it had some kind of 'tranquilizer patch' that was inducing a drug state! No way. This works perfectly, and saved our relationship with our dog. Interestingly, she no longer chases the mail at the door, with or without the Thundershirt; and all other causes for nerves seem to be magically gone. There seems to be a wonderful residual effect when we remove the Thundershirt as well; as the dog stays calm and likeable for hours.
I am certain that using the Thundershirt has given our puppy a new "Leash on Life", so to speak. When wearing the Thundershirt, she is calm and likeable. You can tell that whatever nerve endings that were exposed and giving her the problems are absolutely salved by the Thundershirt. However she was being tortured by vibrations, sonics, other dogs, or whatever, is GONE! Believe me, we are absolutely on cloud 9 now that we have found a non-medicinal solution to our Pom-Chi's (and our) woes!

Il calme le chien et le rassure par sa taille ajustée qui enveloppe le chien. A recommander aux propriétaires de chiens peureux ou anxieux.
