Useful Information

Before putting ThunderShirt on your dog for the first time, offer a small food treat to your dog using the folded ThunderShirt as a “plate”. Dogs typically become more comfortable and trusting of something that “brings” them food or anything that they associate with food. So this is an easy little trick to quickly create a positive association with ThunderShirt for your dog.

Next, simply follow the “Fitting Instructions.” Leave ThunderShirt on for 5-10 minutes. Following these simple instructions allows you to learn exactly how to use ThunderShirt while the dog is calm and helps to avoid the risk that she might begin to associate ThunderShirt with what bothers her. It can also be beneficial to put ThunderShirt on every 4 to 8 weeks in the absence of anxiety.

Feeding Instructions:
Size Pet Weight Chest (Most Important)
XX-SMALL up to 7 lbs 9-13 inches
X-SMALL 8-14 lbs 13-17 inches
SMALL 15-25 lbs 17-21 inches
MEDIUM 26-40 lbs 21-25 inches
LARGE 41-64 lbs 25-30 inches
X-LARGE 65-110 lbs 30-37 inches
XX-LARGE 111 lbs and up 37-50 inches

Please make sure to measure your pet for the best possible fit. If your pet measures between two sizes, we advise ordering the larger of the two.

My formerly feral dog loves her T-shirt!
May 29, 2018
I am so grateful for who ever came up with this product.
I also give her 2 composure tabs & a calming Bonie.
The Zuke's calming treats also work well. I cannot tell the difference between the effect of Composure or Zukes altho they have different ingredents.

Seven year old Chihuahua immediately get tense, scared, nervous when ever she would hear loud noises. And the Holiday Fourth of July would be a nightmare. I received the Thundershirt on time for the rescue during the Holiday. When I heard explosions I immediately put the Thundershirt on her and she did try to hide, nor was she nervous. To my surprise she walked around clam and stayed around me. I need to purchase another one for her nephew. I am a senior of age and money is short, however I had to make this purchase for her. Thank you Thundershirt.

My dog is scared of just about everything. She recently had surgery and wasn't doing so well. We put a Thundershirt on her and her attitude improved immediately. It's truly amazing. She loves the shirt and practically lives in it. A tremendous addition to our wardrobe!

so far so good

The product works for our Jack Russell. I measured our dog and used the chart and dog's chest for sizing but the large was oversize overall. I had to chop and resew for a proper fit. More size dimensions should be given for online ordering. The Thundershirt also doubles as a winter coat for our cold natured Jack Russell.

Works Great!

We haven't had any severe thunder storms since I bought it, but the little storms we've had, this shirt has been awesome. My boxer loves it, she sleeps like baby when she has it on.

not miracle but??
September 22, 2014
It doesn't take away the dogs anxiety completely but it does help them calm down some what. It doesn't work on our little staffy because he tries to take it off by rubbing it on the walls and corners. I am happy with it because at least it helps them a little. Wish it was a 100% miracle but it's not, but then again any help is good especially when there is thunder or fireworks.

I accidentally ordered the wrong size shirt. Entirely pets would not exchange it. Luckily, the thunder shirt company exchanged it. I wouldn't order from entirely pets again.

Thunder Shirt
July 6, 2014
This is nothing short of a miracle. My 12 year old dog has been terrified of thunder storms, heavy rain, and of course very loud noises such as fireworks. The day the Thunder shirt arrived we were expecting a heavy rain in the evening. My husband and I got KC out of he closet where she was already hiding and put the shirt on her. The transformation was unbelievable. She still panted a lot but laid on the dog bed at our feet and was quite content in spite of the storm! A blessing for KC and us.

Seems to be pretty effective & calming. Shelby is a pretty hyper young dog, so I'm pretty satisfied with the results when I put the thundershirt on him.

Questionable product...
March 28, 2013
My dog gets stressed out whenever the doorbell rings.. He barks like crazy... I placed this on him a couple times and nothing changed, he just is tense but still barks.. Now I'm stuck with the product and need to find a new use for it. Maybe something to keep him warm in cold weather? Disappointed in purchase...

About 3 yrs ago, my older (now 12) Brittany started being a terrible traveler. She would circle, try to dig thru the carpet, pant and shake whenever we put in in the car - whether for 10 minute trips or 10 hr trips. We were having to sedate her with Benadryl if we had to travel any distance. I dislike sedating her, especially at her age, so I was hoping for a miracle. I followed the shirt instructions to the letter. After I got it on, we took our usual mile walk, and then I put her in the car for a short trip to get coffee. Instead of her usual reaction of panting, shaking and digging - she walked to the back of the car and then lay down - as calm as could be! It hasn't all been perfect - I've had an 2 incidents where she did her shaking - but after giving her a treat - she was good. She is very comfortable in the Thundershirt - doesn't try to take it off or bite at it. We went to the vet for a checkup and the vet asked me how it was going with the Thundershirt and I said I would highly recommend it. At least give it a try.

I wasted my money on The Thundershirt
October 29, 2012
I have read mostly positive reviews with a few negative reviews. Mine goes in the negative category. We saw no improvement whatsoever by using The Thundershirt. I sat up for 5 hours with my dog while he was wearing it. It didn't calm him at all so we tried it on another dog who also gets anxious during storms. Still no help. I wish I had no wasted my money on it.

From Skeptic to Believer
July 25, 2012
After reading many reviews regarding this product, we purchased it for our 68 lb dog, a ten year old male, who every year had to receive prescription sedation due to the fireworks. No more sedation. Seems too good to be true, but it isn't. This thundershirt works well in lightning storms as well. We kept the packaging and receipt as we were convinced we would return the shirt, now, we'll fight ya to keep it...well, almost. Try it, you'll go from skeptic to believer too. It works!

We got the thundershirt for our 9 year old Chow/Golden Retriever mix who is frightened of 2 things, thunder and fireworks. Got the shirt a week before July 4th and he wore it a few times when nothing was going on. Had a thunderstorm and fireworks on the 4th so a real test. He was still nervous but not as clingy and not panting like during previous episodes. I put the shirt on him and put him in his crate with a blanket over the top and sides and he really did seem way calmer than in previous storms. Hopefully, we will get way more storms this season to give it a real good test. I'm glad I bought the shirt. Easy to put on and the dogs seem to like it. No resistance to being "bundled up".

Review for Thundershirt Sport Dog Anxiety Solution - MEDIUM
July 8, 2012
The thundershirt works for my dog. When fireworks or a storm is present, he lays down and waits for the event to pass. Not 100% calm, but no more hiding under furniture, knocking things over or trembling and shaking. Well worth the money and no more possibly harmful chemicals given for sedation.

Didn't really do a thing
June 28, 2012
My Min-Pin/Rat Terrier mix goes ballistic at anything slightly resembling fireworks. I was hoping the Thunder Shirt would be just what he needed to stay calm. Unfortunately it had virtually no effect. I'm not suggesting it doesn't work for others, but for my little guy it didn't.

Not quite what I expected
June 5, 2012
I am a little disappointed in the Thundershirt. The first one was too small and the 2nd one seemed too big. But neither size was able to calm our Boxer, Molly, down in the car. She continues to pant uncontrollably while in the car and cannot sit still. I have to keep her leashed while in the car and keep a tight reign on her while driving.
I was so hopeful this was going to be the answer to taking her along on rides.

Good reviews but didn't work for us
May 5, 2012
We had a different brand called Anxiety Wrap for our last dog and it helped her. Our current puppy, Prancer, has many issues including fear of car rides, strangers and other dogs. He is disabled and cannot currently walk. He is on medication for these, but it was recommended that we try the ThunderShirt. Since they have a moneyback guarantee, we tried it. It didn't work for Prancer and has been returned. Don't let this discourage trying the ThunderShirt. It could be just what you need.

thunder coat
January 25, 2012
This is a wonderful product. I was excited to discover it as I have in the past put my dog's CFD on him when he was anxious and he would calm right down. Now he wears his thundershirt thankfully when he is in the house.

Excellent purchase for an anxious canine
November 25, 2011
I rescued a 5 year old anxious beautiful boxer girl. Since I am 80, we work well together - she goes everywhere with me but is anxious when I leave the car so while I rehearse my bari sax with the Yachats Big band for 2:30 hours she is less stressed when I return to the car! Once the vacationers come to shoot their illegal fireworks on the beach in front of our house - the shirt will help I am sure since when I wrapped her in a blanket this summer that helped. Great product - go for it!

My dog is older and very nervous when it comes to thunder. He is already on meds for other problems and did not want to add anymore. I was desperate to find relief for him and us. I have used this vest a few different times (no thunder yet). It is great!! He calms down enough to relax. I would recommend this vest.
