Guaranteed to Reduce Your Dog's Anxiety or Your Money Back!

Whether the problem is thunderstorms, fireworks, travel, shyness, separation anxiety or even problem barking, Thundershirt's patent-pending design applies a gentle, constant pressure that has a dramatic calming effect for most dogs.

Based on surveys completed by over two thousand customers, over 80% of dogs show significant improvement in symptoms when using Thundershirt. Thundershirt is already helping tens of thousands of dogs around the world, and is recommended by thousands of veterinarians and dog trainers.


  • Drug-free and completely safe.
  • Soft, breathable, washable fabric.
  • Patent-pending design makes Thundershirt very easy to put on and to take off.

As for WHY Thundershirt’s gentle pressure works to calm a dog, experts such as Dr. Temple Grandin believe that pressure has a calming effect on the nervous system. Using pressure to relieve anxiety has been a common practice for years. For example:

  • TTouch dog trainers use pressure to address a wide variety of anxieties.
  • Veterinarians use pressure to relax cattle when they are administering vaccinations.
  • People with autism use pressure to relieve their persistent anxiety.
  • Children with certain behavioral problems use pressure shirts and weighted vests to relax and focus.
  • Parents use swaddling to calm an inconsolable newborn infant.

Until now, there just hasn’t been a well-designed, inexpensive pressure wrap commonly used for dog anxiety. Thundershirt is changing that! Thousands of veterinarians and dog trainers now recommend Thundershirts for their anxiety cases.

How to use Thundershirts

Thundershirt is an excellent treatment for most types of dog anxiety and fear issues. For many anxieties, we recommend just putting on a Thundershirt and observing the results (No training!). You very well may see significant improvement for noise, crate, travel, barking and others with absolutely no training. For more complicated anxiety cases, we recommend using Thundershirt as part of a behavior modification program.

One thing is for certain, for a very large percentage of dogs, Thundershirt’s gentle, constant pressure has a terrific calming effect. This has obvious benefits for most types of anxiety. But Thundershirt is also a very useful tool for managing excitability or hyperactivity with strangers, on the leash, or in a training environment. Thundershirt’s calming effect helps a dog to focus (or refocus) her energies in a more constructive direction, allowing training to be more effective.

Introducing Thundershirt to your dog

Before putting Thundershirt on your dog for the first time, we recommend offering a small amount of food to your dog using the 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. Thundershirt has been developed to be very easy to put on. Just lay it over your dog’s back and secure with the chest and torso straps. The Velcro fasteners make Thundershirt very adjustable to many different body shapes. See the illustrations and video for more information about how to put Thundershirt on. Or click here for the instructions included in the packaging.


Sizing is best determined by your dog's girth measurement as it's important that the shirt fits snuggly for the compression to work. Please be aware that there is some overlap between the sizes. Select the size where your dog's girth measurement is most in the middle of the size range.


"We've been using Thundershirt at my clinic, and the feedback from our clients is very positive. Thundershirt is a good alternative solution to try versus medications. And it will definitely 'Do no harm'." Dr. Donald Heagren, DVM / Cornwallis Road Animal Hospital, Durham, NC

"Overwhelmingly, Thundershirt has been a success with our cases for thunderstorms and fireworks." Dr. Mark Guise, DVM / Lockwillow Avenue Animal Hospital, Harrisburg, PA

"I have used Thundershirt with my own dog and have seen a real improvement with her fear of thunderstorms and other loud noises. I am now recommending Thundershirt to my clients with good results." Dr. Joanne Baldwin, DVM / Cardinal Animal Hospital, Richmond, VA

"In my experience as a Certified Pet Dog Trainer and dog owner, the Thundershirt can dramatically relieve a dog's anxieties associated with thunderstorms, fireworks, travel, etc. The even, gentle pressure of the Thundershirt can refocus the dog to a more relaxed, calmer state. Using Thundershirt to relieve the symptoms of anxiety is a good alternative to medications and at $36, it’s a terrific value." Jenn Merritt, CPDT / Efland, NC

"Before receiving her Thundershirt, Rage would shake drool and actually broke through a window last year breaking her leg trying to 'escape' from a thunderstorm. After putting Thundershirt on her, wonder of wonders, during the next storm she actually laid down and was chewing her Nylabone, not paying any attention at all to the storm. It was like a miracle! I strongly recommend the Thundershirt for any dog that has anxiety issues. It is wonderful!" AB / Cleveland, Ohio

"Thundershirt has an amazing effect on our two Shi Tsu's, Elli and Emma. Anytime visitors come to our home, they will bark nearly non-stop with Elli being the ring leader. Most times, we would have to confine them in a back room until our guests left. But Thundershirt has had an almost immediate effect - within seconds after putting it on, Elli is much more relaxed and the barking quickly subsides. She's happy with her tail wagging and she's able to be a polite and QUIET member of the group!" BB / Durham, NC

When we fitted the Thundershirt to Maverick a Golden Labrador,(15 months Old) he behaved well.
We left him in the House in his Bed, and went out for 3 hours, ,if he was not in the Thundershirt, he would started on chewing picture frames of the Grandkids, and then onto the Grand Children's toys.
For the duration of our outing, Maverick did not destroy a thing .
This Thundershirt is GREAT>

We have a staffy that we rescued She is 4 and been with us for a year now Sadly the jacket has not helped her anxiety she is still terrified of the lawn mower or anything similar She is scared even when my partners sneezes I think she has major anxiety issues and the next step for her is probably medication but will try a bit longer yet with the jacket as would prefer this to medication.

Bella was our rescue Staffy and seemed to chew whenever she was with our other dog Lottie, it was only my things she chewed so Staffy rescue said try the thundershirt which we have and she seems to have settled down so far, I am hoping she keeps the goodness up. Bella seems to enjoy having it on, it will be interesting to see how she goes with a storm a s she I s terrified of them.
Great stuff guy's thanks

Tamara Wright WE have a little black pug called Ruby who is always freaking out at every little noise. We bought the thunder jacket in the hope that she would feel more secure and not so nervous. She loves wearing it and has settled down a whole lot. She now only barks when there is heaps of different noises going on.

This jacket is well made, very soft and comfortable for my English Pointer. He is a much happier puppy when he is wearing his jacket.

Hello, we bought a little Cavoodle rescue dog, "Caddy". We have had her for four months, and she was always so frightened of everything. When men came to the house she would become hysterical with no chance of settling down. We had no idea of her past history but were constantly looking for ways to help her deal with the world. Although she was only 10 months old she would never play, just wanted to sit on my lap all day long. The first time we used the thunder shirt, a friend had arrived and Caddy was beside her self with stress and anxiety, barking every time my friend moved. We put the thunder shirt on and she immediately sat very calmly and allowed my friend to pat her. We left the shirt on for half an hour and then took it off her. She was still calm. I can't recommend these shirts highly enough. Now Caddy plays, is relaxed and happy, she is a different dog. Sooooo happy and joyful.

Put the jacket on Kane once he heard the thunder. Within 15 minutes he had calmed down with no shaking, heart pounding and panting. He even came outside with us and sat under the eaves while we watched the rain etc.

The Thundershirt is easy to use with a quality finish. I was sceptical about it having an effect on our 19 year old dog Hettie who is experiencing lots of anxiety at loosing her sight and hearing. However, within moments of putting it on she was more relaxed. It has reduced (nearly stopped in fact) her obsessive anxiety licking, she settles more quickly to sleep when wearing it and now she wears it for most of the day and night. When we put it on she gives a murmur of contentment - that tells me that for its a great addition to her life.
