what if the dog chews it, can i get a refund
Answer by KatieJul 06, 2022
My dog weights 20= 25 lbs what size should i get her.

How does this work with separation anxiety?
Answer by ChewyDec 11, 2017
The ThunderShirt uses gentle, constant pressure to calm anxiety, fear, and over-excitement. This gentle hugging produces a dramatic calming effect while slowing the heart back down to a normal rate.

Can you have this on your dog all day?
Answer by ChewyMay 13, 2022
Most people say that their dogs and cats really enjoy wearing their ThunderShirts and they are safe to leave on for extended periods of time depending on the issue. But, please note! We recommend removing ThunderShirt every one to two hours the first few times to be sure everything is fitting correctly and your pet is happy. Irritation or other issues are very rare, but it’s always best to be cautious. AND, always remove the ThunderShirt at least twice a day if used for extended periods.

Please provide the length measurements - for the small and the medium. Thanks
Answer by ChewyJul 09, 2019
The lengths are as follows: XX-Small - 7 inches, X-Small - 8.5 inches, Small - 12 inches, Medium - 14 inches, Large - 18 inches, X-Large - 21 inches, XX-Large - 22.75 inches.

Amazing Thunder Shirt!!

Our dog Ziggy, has a terrible time with thunderstorms, fireworks, and gunshots. I had put the Thunder Shirt on him once when we got it last week. Today there were gunshots and his sister was barking and I put it on him just to see what he would do. I gave him a treat and then I didn’t really pay attention. This is a dog that normally would be under the bed shaking and you would know it because the bed was shaking. Amazing results-he was looking out the window to see what she was barking at then he curled up on the couch relaxed! He then went to the bed BUT he was on top of the bed instead of underneath I would recommend this to anybody!!!

It’s magic

This thing blew me away. My dog often gets spooked at night and barks into the yard endlessly because of hearing animal sounds and wind. She calms down when I massage her back so I figured this would work. We put it on and she immediately calmed down and within 15 minutes, she was calmly asleep. Later, she woke up and played in the yard at night without a care in the world. She didn’t bark the entire rest of the night, even once we took it off! I’m amazed. For reference, she is 50 lbs but has a thin build. The large fit her well. I think medium would have been slightly too small.

Works well with reactive dog

Oh my gosh. I bought this thunder shirt on a whim because I know my dog is very anxious. The majority of his reactiveness comes from fear, so I thought if I tried this it could possibly help. And it did! His first time wearing it, I had a surprise visit from a relative that my dog usually is shaking in fear over. He barks, growls, hides, etc. While wearing the thunder shirt, he didn't bark at all, came up to her and sniffed her, and let her give him treats! Every now and then I'll put it on throughout the day, and when I do- he falls right asleep. This shirt works 10x better than the adaptil stuff or the calming chews. It didn't solve his reactiveness completely though, just made it a lot easier to train through and handle. I would 100% recommend this, it is totally worth the money considering how expensive other treatments can be.

It helped my scary cat dog, Kai

Kai usually shakes and shuffles in bed every time she sees lightening or hears thunder. With the Thundershirt she was just shaking because of the lightening and we were able to console her under the blanket where she couldn't see lightening. She went right to sleep, as did we and weren't exhausted the next day. It rides up the neck a little so you need to watch that closely as to adjust, because she couldn't get it off in distress because of the tightness. But other than that, it's perfect.

My Scared Boy Made Brave

Love this product. Took several tries to figure out how to get it fitted to my boy, and for him to let me put it on. He's afraid of many things, storms in particular. Today I had a crew over to trim trees and knew that would be awful for him. I brought out the Thunder Shirt, and he ran over wagging his tail, and made it through the whole tree trim with no trembling. Amazing.

Didn’t do Anything

My dog has bad separation anxiety. My wife and I sat on the porch with the screen door open so our dog could see us while we had dinner. I put the thunder shirt on her to help her relax. As soon as I shut the door she began shaking and started tearing up the standing mat in the kitchen. She shook and panted all night until we came in. It has done nothing. I wish they could let me return it.

not as good as advertised ( for my dog)

I bought this several months ago for my dog who suffers from separation anxiety, this did not help at all. I tried it several times on her in addition to all the recommendations to helping a dog with separation anxiety. I feel like it was a waste of money for my situation. I had such high Hope's for this product It may work great for other dogs but it didnt for mine.

Lightweight and works

I ordered this thundershirt for my 2-yr old Rottie. She is absolutely terrified of fireworks and thunder. I bought an XXL because she is already 105 pounds, and she hasn't stopped filling out...and the dog pictured is a Rottie. It's too big! Because the material is stretchy, the shirt wraps under her snugly, and then the Velcro strips do not make contact. The side flap holds the shirt secure. If your dog is on the size bubble, I recommend ordering the smaller size.

Amazing...It really works!

After experiencing our pet's anxieties over thunderstorms and fireworks we tried some meds from the vet but she became lethargic and suffered constipation. When we heard about the ThunderShirt, we thought we found another remedy to try. We live in South Florida where thunderstorms are frequent and the Holiday fireworks go on for at least a week. On the very first wearing, Veda remained calm, no shakes and she ate her meals. Were just so happy to have found a non-agressive solution to the sound anxieties.

THUNDER SHIRT

I really like this item. Sophie shivers so bad when thunder approaches. Putting on the ThunderShirt and giving her one calming chew calms her down in about 30 minutes.
