Our Bernadette suffers from periods of intense anxiety and after a few trips to the emergency vets and researching the symptoms with her regular veterinarian, we purchased this shirt and it has made such a difference. During these episodes, she pants rapidly, scurries under our feet, climbs above our heads on the couch, recliner and in bed and nothing we do helps to calm her down. This shirt does sort of makes her freeze, but it’s similiar to how she acts when we put a cold weather sweater on her. She lays down generally where we put on the shirt and gives into the calmness. It’s a miracle!! It is science based though, similar to swaddling a human baby. It brings her comfort. We pick her up and cuddle with her and she wears it for about 30-45 min to help ease her fears. We always have it with us on trips to our campground just in case something triggers her.

I bought this because my GSP was diagnosed with ulcers, and we were trying to avoid anxiety meds. She seems to enjoy wearing her thunder shirt, and I feel like she is more restful when wearing it. It unfortunately did not eliminate the need to try meds for anxiety. I do recommend the product. Just don’t expect it to work miracles.

The outstanding customer service.

We'd bought a Thundershirt for our Aussie, Lego, who is terrified of thunder and fireworks - and it worked pretty well, but after only a few wearings we noticed

We'd bought a Thundershirt for our Aussie, Lego, who is terrified of thunder and fireworks - and it worked pretty well, but after only a few wearings we noticed that the edges of the Velcro strips were pulled loose in a few spots where the stitching had simply missed catching it. Called to see about a return and was offered a quick free replacement, no return necessary! Quick, easy, a pleasure to do business with, and the new one arrived in time for New Year's Eve fireworks. Yay!

Unfortunately it didn’t work

My poor boy is TERRIFIED of fireworks. I got a thunder coat for him and it didn’t do anything. He hides in the bathroom, pants, shakes and tries to wedge himself

My poor boy is TERRIFIED of fireworks. I got a thunder coat for him and it didn’t do anything. He hides in the bathroom, pants, shakes and tries to wedge himself between the wall and the toilet, which he doesn’t fit. For the past 2 years, I’ve spent NYE in the bathroom with him. I’ve tried everything too. Calming chews, thunder coats, even massage. My head massager seems to work the best. I wish there was something I could do!! It’s heartbreaking. My girl starts shaking because she sees him shaking. It’s so sad.

Good for anxiety

Our guy is getting older and gets anxious at night. This combined with the thunder Ease calming spray (there’s a patch right in the shirt where you apply 3/4 sprays)

Our guy is getting older and gets anxious at night. This combined with the thunder Ease calming spray (there’s a patch right in the shirt where you apply 3/4 sprays) seem to help him. Make sure you measure. We got a small and it’s still a little big for him when he usually wears a medium in other things.

Great quality. Fit snug. Didn't work

I thought it may help my aging 9yr 100lb dog. We tried it on and he didnt seem to mind it at all. When his fear and anxiousness kicked in and and we put it on,

I thought it may help my aging 9yr 100lb dog. We tried it on and he didnt seem to mind it at all. When his fear and anxiousness kicked in and and we put it on, no difference at all was noticed. Just doesnt work for this dog.

Helps

Field golden in her 4th year of life decided to become scared of thunder, she hides, paces, shakes and is generally super stressed to the point where I have to hold

Field golden in her 4th year of life decided to become scared of thunder, she hides, paces, shakes and is generally super stressed to the point where I have to hold a towel over her head to get her to calm down, so I was willing to try the jacket. she definitely is calmer, however I think its the distraction of having it on to begin with thats the help. She still hangs out right next to me but the pacing and panting has stopped, but make sure to put it on them when there's not thunder, she gets a little anxious when she sees it coming out, and fights me a little to get it on, but once its on she's good. Worth a try for anyone looking for help with the anxiety and nervousness with storms.

Six year old, Charli, shakes and pants during car trips. T-shirt seemed like a great solution. She willingly wore the shirt, no issues. However, it did not provide any relief. In addition, she struggled to move about and/or lay down. Disappointed that this was not the solution for her.

It is well made but I didn’t see a difference in her response to fireworks. I was hoping the undershirt, her ear muffs, calming chews and prescription would keep her calm and it did for awhile but once she heard noise it was all over.

Sizes are not accurate

I purchased a XL because my dog is 105 pounds. But, the XL was too small for my dog. I have to return it for an XXL- what a pain.
