Answer by KatieJul 06, 2022
My dog weights 20= 25 lbs what size should i get her.

How does this work with separation anxiety?
Answer by ChewyDec 11, 2017
The ThunderShirt uses gentle, constant pressure to calm anxiety, fear, and over-excitement. This gentle hugging produces a dramatic calming effect while slowing the heart back down to a normal rate.

Can you have this on your dog all day?
Answer by ChewyMay 13, 2022
Most people say that their dogs and cats really enjoy wearing their ThunderShirts and they are safe to leave on for extended periods of time depending on the issue. But, please note! We recommend removing ThunderShirt every one to two hours the first few times to be sure everything is fitting correctly and your pet is happy. Irritation or other issues are very rare, but it’s always best to be cautious. AND, always remove the ThunderShirt at least twice a day if used for extended periods.

Please provide the length measurements - for the small and the medium. Thanks
Answer by ChewyJul 09, 2019
The lengths are as follows: XX-Small - 7 inches, X-Small - 8.5 inches, Small - 12 inches, Medium - 14 inches, Large - 18 inches, X-Large - 21 inches, XX-Large - 22.75 inches.

Lightweight and works

I ordered this thundershirt for my 2-yr old Rottie. She is absolutely terrified of fireworks and thunder. I bought an XXL because she is already 105 pounds, and she hasn't stopped filling out...and the dog pictured is a Rottie. It's too big! Because the material is stretchy, the shirt wraps under her snugly, and then the Velcro strips do not make contact. The side flap holds the shirt secure. If your dog is on the size bubble, I recommend ordering the smaller size.

Amazing...It really works!

After experiencing our pet's anxieties over thunderstorms and fireworks we tried some meds from the vet but she became lethargic and suffered constipation. When we heard about the ThunderShirt, we thought we found another remedy to try. We live in South Florida where thunderstorms are frequent and the Holiday fireworks go on for at least a week. On the very first wearing, Veda remained calm, no shakes and she ate her meals. Were just so happy to have found a non-agressive solution to the sound anxieties.

Thunder shirt issue

I recently purchased the thunder shirt in hopes that my pup would calm down through the July 4th celebrations as well as thunderstorms this season. Unfortunately, the Velcro adjustments were so loud for him that he wouldn’t let me put it on him. I laid treats on it and let him sniff it for a few days, but he was just not letting me put it on. I haven’t given up yet, but it might be a good idea to use a different type of material to attach snuggly that isn’t so noisy.

Amazing customer service, Chewy never disappoints!

Originally we bought a small size for our anxious Chihuahua three days before the fourth of July. It was too big for her and we sent an email to chewy asking if we could get a smaller size. Not only did they respond to our email the same day, they even sent the smaller size the very next day and we had it in time for the fourth!! I recommend chewy to everyone I know, their customer service is excellent and their products never disappoint.

Thundershirt

We’ve been having some pretty loud storms lately. Driving my one dog crazy, so I ordered one for each dog. Other dog is just nervous. They both wear them when weather is questionable. And do much better. I’m glad I made this purchase. Wish I’d done it earlier.

Wish it worked for car anxiety

My 1 year old pup started to show signs of anxiety when riding in the car at higher speeds. I wanted to explore methods that didn’t involve medicating her so I purchased the thunder shirt. I trained her with it for weeks before we took it into the car. She loves to put it on because she knows she gets all the good things, snuggles, play, treats and walks!! We also kept it in our laundry basket so it smelled like us. I didn’t notice any changes in her day to day behavior, and unfortunately upon trying it in the car it didn’t have any effect on her. My pup pants heavily, yawns, and her body trembles any time we get on a highway. We are going to try a medication prescribed by the vet instead and hope that helps, maybe we will still wear the thunder shirt in the car and hope that it eventually helps her.

Great Product

We recently moved to Florida -- where we seem to get thunderstorms every afternoon! We came from a desert climate and Brody wasn't used to thunder. This shirt has helped immensely -- the minute he hears thunder (sometimes before I do!) he runs to me to put on his thunder shirt! I would recommend it to everyone!

Got a workout over long July 4th weekend

My first 4th as a dog mom. Heidi (20 month old Labeagle) has anxiety like many rescues. My holiday tool box included a Thundershirt, calming chews, anti-anxiety med, premium treats & new toys bound for a squeakectomy! This combo worked well for us. There was an adjustment period for the Thundershirt, but in the end, she didn’t mind it. I plan to use it for any high stress situations from now on!

Works well

I have a 55 lb lab pit mix who hates thunder and fireworks. Storms have been pretty bad so we got her this, she normally shakes and tries to hide. We got her this thunder shirt (size large) and gave her some calming chews and she was calmer than she has been.
