Thundershirt Review

  • Price: $29 to $45 depending on size and place of purchase
  • Guarantee: Yes
  • Founder: Phil Blizzard

The Thundershirt was created to reduce or eliminate anxiety in dogs and cats. The Thundershirt has an 80% success rate with dogs and cats. It is made from a thin durable fabric that is breathable.

Machine wash with regular laundry detergent in cold water. Hang it to dry. It comes in a variety of colors, styles, and sizes from XXS to XXL.


Recommended sizing for dogs below is from Thundershirt.

  • XXS is for dogs 7lbs and under
  • XS is for dogs 8 to 14 lbs
  • S is for dogs 15 to 25 lbs
  • M is for dogs 26 to 40 lbs
  • L is for dogs 41 to 64 lbs
  • XL is for dogs 65 to 110 lbs
  • XXL is for dogs over 110 lbs


The Thundershirt is for dogs and cats that suffer from anxiety and fear. Do thunderstorms or loud noises frighten your dog or cat? Maybe your dog becomes stressed when you are away. Your pet may suffer from anxiety.

Anxiety and fear can cause excessive barking in dogs. For some pets, traveling can cause anxiety. It doesn’t matter what type of anxiety or fear, the Thundershirt will help 8 out of 10 dogs and cats.


If your dog has anxiety, they may exhibit one or more of the signs below.
• Shaking
• Howling
• Whining
• Excessive barkingdog hiding
• Excessive drooling
• Tail tucking
• Hiding
• Pacing
• Panting
• Excessive licking
• Excessive chewing
• Destruction
• Reliving itself inside


The design creates a gentle pressure on the torso, like swaddling an infant. This gentle pressure provides a calming effect. To use the Thundershirt, no training is necessary. Why medicate when you can use the Thundershirt.

Most dogs will show good results the first time wearing it. For some, it may take two to three times using it before you see good results. For severe anxiety, you may need to work with a behavioral specialist along with the Thundershirt.


I bought my dog a Thundershirt because she suffers from separation anxiety. She would howl and whine while I was away. I put the Thundershirt on her at least 30 minutes before I leave, because I don’t want her to associate the Thundershirt with me leaving.

An improvement was seen the first time she wore it. Starting out, I left her alone for a few minutes at a time, then I would increase the time that I was gone. I am amazed at the difference it makes with her anxiety, and she loves to wear it! Not everyone’s experience will be the same as mine.

A friend of mine has a dog that is terrified of thunderstorms. He would shake and tremble with fear during thunderstorms. Then he got a Thundershirt and his world changed. The moment his owner put the Thundershirt on him, he immediately became relaxed and calm. Now he is a happy dog during storms wearing his Thundershirt.


I recommend the Thundershirt if your dog suffers from anxiety or fear. It has been proven to help 80% of dogs and cats with anxiety and fear. Try the Thundershirt for you and your dog. What do you have to lose? If you dog is one of the 20% that it doesn’t work for, you can return it to the place of purchase.

  1. What a great idea! My cousin’s dogs go crazy during New Year’s and the 4th of July because of the fireworks. She really needs to try this out. So far, everything else she has tried hasn’t worked. This could be the thing!
    Great post!

      I hope it works for your cousin’s dogs. Be sure to share the post. Remember it has a money back guarantee! Thank you for your comment.

  2. Hi Alice,
    thanks for this great review of the Thundershirt! I think I’m going to give it a try. My American Bulldog female is very sensitive and anxious for loud noises, especially fireworks and thunderstorms. If this can help calm here, it is worth every cent. She is about 62 to 64 lbs, do you think I should go for the large or should I take the XL, since she is on the limit of both?

    Thanks for your help!
    Best wishes,

      Hi Stina, I hope it helps your dog as much as it helps mine! My Basset Hound is 52 pounds and she wears a large. There is a lot of room for adjustment. A much bigger dog could wear a large. I think she will be fine with a large. Good luck! Thank you for your comment.

  3. I wonder how well this works for cats? Do you know of anyone that has tried it and been successful with a cat? One of my cats gets seriously distressed and cries when I leave. I feel so bad when I come home and I can hear him crying before I even get to the door 🙁

      Yes, the Thundershirt does work on cats too! Just like with dogs, it will work with most cats. It will give them the same calming feeling that it does for dogs. Some veterinarians use the Thundershirt for dogs and cats that become stressed in their office. Get the Thundershirt for cats and if your cat is one of the few it doesn’t work for, you can always return it and get your money back. Best of luck!

  4. Thanks for your answer Alice! Then I will definitely order the large one.
    I will let you know how it works later. Hopefully it will help her get some comfort.
    Thanks again.
    Best wishes,

      You’re welcome, Stina! I hope it brings comfort to you and your dog! I’m looking forward to hearing the results!

  5. Hi again Alice,
    Just a little update. I purchased the thundershirt in large like you recommended and it fits Abigail perfect, thank you! She seems to like it and become a bit calmer whenever there is loud noises. My neighbor cut down their tree yesterday, which made terrible noise. I put it on and she seemed calmer.
    Thanks again for letting me know about this product:-)
    Best wishes,
