  1. Tessa

    Had the Thundershirt for my dog due to issues with storms and fireworks. She is used to getting dressed up and took to the shirt very well. Within 48 hours of having it, a very long lasting storm rolled through and the difference in her was amazing. Sleeping through the majority of the storm, not roaming from room to room or following us as our heels and no stress panting. I wish we had purchased one earlier!

    I was gifted a product sample to trial and review.
    It was easily fitted to my young adult labrador female. The material felt like quality and did not irritate her skin
    From the first night she no longer barked to storms and airplanes. Had a great sleep. Would definitely recommend. Easy to wash also

    My German Shepherd does seem more relaxed with the jacket on.

    Great Product

  5. Barbara W.

    My Retriever is so much more peaceful when the storms hit. He actually starts wagging his tail when I get his thunder shirt out.

    I put the shirt on our Great Pyr and walk her around a little while and she will calm down and can come back to bed. She must hear or sense something that scares her at night and starts pacing and barking which wakes everyone in the house. Once I assess that no immediate threat is present, out comes the Thundershirt. Otherwise the barking can go on for hours.

    Since my dog Riley has died, my other dog is having issues with anxiety. The Thundershirt has helped her feel calmer, she rides in the car with less stress and is showing signs of courage.

  8. Sally M.

    My dog is scared of storms and fireworks, this does help calm her.
    Also has separation anxiety when I have to leave her alone and bites herself. Thunder shirt has helped with this issue even more.
    Thanks! Will buy again.

    It works great. Our lab shakes severely whenever there are fire works, thunderstorms. This ThunderShirt has helped him so much. I would recommend these without hesitation.

    Our rescued dog is terrified of thunderstorms, car rides, loud noises, just about anything that can induce anxiety for him does. Our vet had given us a sedative to use during thunderstorms for him. Almost 2 hours after being given the sedative, it didn’t work at all on him. I drove to the pet store quick and purchased the thundershirt. Followed the instructions and no sooner than I finished strapping the shirt on him he started calming down. Within 15 min of having the shirt on he went and laid down with one of our cats and fell asleep.

    I bought this because everything that I tried for my dog didnt work. He is scared of thunderstorms he has anxiety he has social anxiety and he has separation anxiety plus hes scared of everything. This shirt made a big difference with him and I have been recommending it to everyone I know who has a dog that is scared. So thank you for this product its amazing
