Classic Gray ThunderShirt

Love 'em like a hug. Love 'em with ThunderShirt

ThunderShirt is vet recommended¹ and may help calm your dog in stressful situations. ThunderShirt applies a gentle, constant pressure to your dog’s torso, like swaddling an infant or a comforting hug to help them feel calmer.

ThunderShirt is safe, easy to use and drug-free. There is no training required to use ThunderShirt, simply put it on your dog.

thunder

fireworks

travel

separation

For many dogs, thunderstorms can be a terrifying experience. Using ThunderShirt can reduce panting, drooling, shaking and other signs of anxiety. If your dog is still nervous during storms try closing the blinds and leaving their crate or kennel open with a blanket to create a dark “safe space.” Some dogs are not just scared of the sounds but also the flashing lightning of a storm.

Due to the fireworks, 4th of July is one of the biggest days for pet stress of the year. ThunderShirt has helped millions of dogs stay calmer during the holiday. Make sure your dog can stay inside during fireworks so they do not get scared and run away and become lost. A collar with updated contact information and a ThunderShirt will help your dog stay safe and calm during fireworks and loud noises anytime of year!

Using ThunderShirt while traveling can make it a more comfortable ride for you and your dog! If your dog’s anxiety with the car comes from them thinking a car ride = a vet visit, taking them on fun, short trips can help them to disassociate the car with negative emotions. If your dog is still stressed, try combining the power of calm with the ThunderEase Spray and ThunderShirt.

Separation anxiety is a bigger concern now more than ever! Even if you wanted to, you can’t be home at all times, so ThunderShirt is a great option to soothe your dog while you are away. Return to office with peace of mind by using ThunderShirt.

Immediate Relief
My pup, a Chi-Pom mix, was the cutest, quiet guy at 1yr when he came to live with me. After three moves in a year, he was pretty stressed. The first move, just six months after I got him, he seemed okay. The second, a month later, there were workers constantly banging in the house and nearly died from sudden gastric distress. I tried CBD and even Trazadone, nothing helped. This last time was to my dream home, but he has remained so anxious he was flinching and barking at every sound and movement for 6 months. The vet gave him probiotics which helped a little. But recently he was getting worse and even getting aggressive toward me. I work full time, but made sure he got a good walk mid day every day. Still he was hyper-alert on overstressed. That’s when I remembered Thundershirts and looked them up. This shirt, which he was perfectly composed to model for this picture 5 minutes after I put it on, saved my dog. It let me by-pass his dislike for having a shirt pulled over his head and delivered the little squeeze he needed to relax. The fit, an XS on his 16” chest is perfect. He is about 8 pounds. I’m so excited and relieved I once again have the pup I’ve been missing for 18 months. Ordering another one today. The best solution for this stressed out little dog.

5.0 out of 5 stars I have purchased ThunderShirts for three dogs in the past four years
Reviewed in the United States on October 28, 2016
This is the third ThunderShirt I have purchased over the last four years. None of the dogs I purchased the shirts for was afraid of thunder, but I have found these shirts to have a calming effect for other anxieties.

The first ThunderShirt I ever purchased was a size XL for an elderly 84-pound labrador retriever to help her deal with the anxiety she experienced following a stroke. It also seemed to give some relief from the itching caused by her meds. She really liked wearing it, and would have gladly worn it 24/7, but I didn't think that was a good idea. I was concerned she would get chafing or circulation problems from overuse, so she only got to wear it for a few hours a day. Still, I think it was an important part of the various things we did to increase her comfort until she was ready to leave this world. After she crossed over, the shirt was donated to help rescued dogs in foster care, and it was much appreciated by the foster "mom".

The second shirt was a size XS that was purchased for a rescued 11-pound rat terrier who has no issues other than sibling rivalry. He wanted to wear a ThunderShirt because his "sister" was wearing one. It also helps give him a little extra warmth in cool weather, which he really appreciates because he chills easily. And he looks really, really handsome wearing it.

The third ThunderShirt was a size XXS purchased a month ago for a 5-pound chihuahua puppy I adopted two months ago. She was found abandoned in a storage container with three other dogs. She was rescued by the county animal control department and given veterinary care until she recovered enough to be adopted. She has issues. Many, many issues. She hadn't been socialized at all and was absolutely terrified of people. She hadn't been potty trained. She was not much more than skin and bones -- you could easily see the outline of every rib. She obviously had been badly abused and she has a leg injury that may never heal completely. She didn't know how to walk on a leash and was terrified to try. She shook with fright for fifteen minutes when shelter staff placed her in my arms. She screamed and screamed and screamed in absolute terror when a very gentle friend of mine tried to pet her.

After a month of training and socialization, and lots and lots of love, my chihuahua had gained a whole pound, was starting to get the idea about where to go potty and where not to , and had learned how to use a doggie door! But she was still exhibiting a lot of fear and anxiety, so I got her the ThunderShirt. I forgot to go through the recommended training process to introduce her to the ThunderShirt, but thankfully it turned out to be one of the few things that didn't frighten her. She loves it! It doesn't make all her issues go away, but it definitely seems to reduce her anxiety. She doesn't have very thick fur, so she appreciates wearing any shirt, but this is the only one that helps to calm her. She, too, would love to wear it 24/7, but I won't let her. With lots of love and positive reinforcement and her new Thundershirt, she is getting a little braver. She can't tolerate a leash attached to her collar, but she loves to walk in familiar places with her [[ASIN:B01FJ44IZY Bright Mesh Heart Printed Dog Cat Pet Vest Harness and Matching Leash Set in Blue for Dogs Cats (Large)]] . She will cuddle with me for hours, but she cowers if I move suddenly or use a stern voice. She is afraid of anyone new, except delivery people. They might be bringing [[ASIN:B005KSOI9G Dogswell Nutrisca Dog Food, Salmon and Chickpea, 15-Pound Package]] or [[ASIN:B006W6YHYQ GREENIES Dental Dog Treats, Teenie, Original Flavor, 130 Treats, 36 oz.]] from Amazon! :-)

I wouldn't call the ThunderShirt a miracle, but I would call it an excellent tool for helping dogs with anxiety issues. It is effective, and it is well-made with quality materials. The latest version has three new features that were not on my original two ThunderShirts: a patch for using a calming spray, snaps for attaching a jacket, and some reflective trim to make your dog more visible at night. Unfortunately, I can't use the calming spray because I am sensitive to one of the ingredients. I would love to get the snap-on [[ASIN:B00PSKFY0I ThunderShirt Outerwear Raincoat, X-Small]], but so far have not been able to locate one in size XXS. I do appreciate the reflective trim because it glows in the beam of my flashlight when I take my puppy out after dark.

I will continue to use the ThunderShirt to help reduce my puppy's fear and anxiety. I will be using it when I introduce her to new situations, and I will update this review to report on how that goes.

The first photo below shows what the ThunderShirts look like from the front, where they can be adjusted with the velcro that is under the front tab. Of course, the photo also showcases how adorable my dogs look in their (almost) matching ThunderShirts!

The second photo clearly shows two of the new features on the chihuahua's ThunderShirt, the patch and the reflective trim at the neck. The rat terrier is wearing the older version of the shirt, which he has had for four years now. He even has his name embroidered on it.

The third photo was taken with a flash to show the reflective trim doing its job.
