About This Item
Details

- Calms your dog during fireworks, thunder, separation, travel, vet visits, grooming, and much more with no training and no medication.
- Comfortable and easy on/off. Made of durable, breathable, soft fabric that is washable.
- Recommended by trainers and veterinarians to relieve stress-related behaviors such as jumping, excessive barking, and inappropriate marking.
- Proven effective in over 80% of dogs.
Instructions
- Before putting ThunderShirt on your dog for the first time, offer a small food treat to your dog using the folded 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.
- Next, simply follow the “Fitting Instructions.” Leave ThunderShirt on for 5-10 minutes. Following these simple instructions allows you to learn exactly how to use ThunderShirt while the dog is calm and helps to avoid the risk that she might begin to associate ThunderShirt with what bothers her. It can also be beneficial to put ThunderShirt on every 4 to 8 weeks in the absence of anxiety.
Size
To get the most accurate size anxiety vest for your pet, measure the girth of their chest, around the widest part of your dog's torso right behind the front legs, with a cloth tape measure. Pull the cloth tape snug, but not tight. If you don't have a cloth tape measure, you can use a piece of string and measure it with a rigid ruler afterwards. If your dog is in between sizes, we recommend that you choose the larger size.

Please use Chest as your main measurement.
| Size | Pet Weight | Chest (Most Important) |
|---|---|---|
| XX-Small | up to 7 lbs | 9-13 inches |
| X-Small | 8 to 14 lbs | 13-17 inches |
| Small | 15 to 25 lbs | 17-21 inches |
| Medium | 26 to 40 lbs | 21-25 inches |
| Large | 41 to 64 lbs | 25-30 inches |
| X-Large | 65 to 110 lbs | 30-37 inches |
| XX-Large | 111 lbs and up | 37-50 inches |
Please make sure to measure your pet for the best possible fit. If your pet measures between two sizes, we advise ordering the smaller as this product works through compression.
FAQ
ThunderShirt's patented design applies a gentle, constant pressure on a dog's or cat's torso. Using pressure to relieve anxiety has been a common practice for years.
For many types of anxiety or fear issues, no training is necessary! Just put ThunderShirt onto your dog or cat and you will likely see results with the very first usage. However, for some, it may take two to three usages to see maximum results. For some more serious anxiety cases, such as severe separation anxiety, you should consult a good trainer for how to integrate ThunderShirt into a training program.
ThunderShirt is made with durable, washable fabric. When necessary, ThunderShirt may be washed in a regular cycle using regular laundry detergent and cold water. Hang to dry.
ThunderShirt is designed to be safe to leave on for extended periods of time when appropriate for the situation or issue. When properly sized and properly put on with a comfortably snug fit, your dog should be very comfortable. If your dog will be wearing a Thunder- Shirt for more than one hour at a time, we recommend removing ThunderShirt every one to two hours during the initial periods to check for any signs of irritation points. Irritation points are very rare, but it is best to be cautious.
We designed ThunderShirt to be very easy to put on your dog and cat, even if she is already in a state of anxiety. It just takes a few seconds and is very easy to adjust for proper fit.
When fitting a ThunderShirt on a male dog, the straps that go around the stomach area should not cover or push on the genitals or prepuce. If the ThunderShirt rubs against the genitals or prepuce, irritation may result. If you see any indications of this, remove the ThunderShirt immediately. Try a smaller size or contact us for other suggestions.
Except in extreme conditions (e.g. 90 degrees Fahrenheit in the sun), overheating is not typically a concern when using a ThunderShirt. Dogs cool themselves primarily through their mouths and paws, and a ThunderShirt is constructed of a thin, breathable fabric. But if you feel that overheating might be a problem for your particular circumstance, please monitor your dog for any signs of overheating such as heavy panting or tongue hanging out of the mouth. Remove the ThunderShirt if you see any signs of overheating.
Most dogs and cats love to wear ThunderShirts! When sized and put on properly, your dog or cat should be very comfortable wearing a ThunderShirt. Problems are very rare, but if you see any signs of skin irritation or physical discomfort, please discontinue use and contact us.

Vest of Protection

I wasn’t sure if this would really work, but it did. There are people in my neighborhood who always light large, illegal, fireworks every July. The police do nothing about it, even though we live in a brushfire zone. I bought this vest for my little Yorkie girl because the fireworks send herb nto a panic. It calmed her down almost immediately. Now, when a thunderstorm comes, I ask her if she wants her Vest of Protection. She eagerly runs up to me and waits for me to put it on. Great product.
Fits well, seems well-made
The XS fits my 7.6 lb Yorkie. Sadly doesn’t seem to help my little dude. He still loses his mind during thunderstorms. I’m going to keep trying it - if it keeps
The XS fits my 7.6 lb Yorkie. Sadly doesn’t seem to help my little dude. He still loses his mind during thunderstorms. I’m going to keep trying it - if it keeps him even a little calmer, it’s worth it
It actually works!

My pitbull is 12 years old. She shakes and pants uncontrollably with thunderstorms and fireworks. I can never calm her down. Calming spray helps a little but not enough. I decided this year with 4th of July coming to give it a try. The picture below is her sound asleep with all the fireworks going off. I have since used it for thunderstorms. Sometimes it only helps a little and sometimes it helps a lot. But it has made her so much more comfortable.
Easy to use and it does help
The Thundershirt has, without doubt, the best velcro of any dog product we’ve ever had. That said, it means that you have to practice with it before you need it
The Thundershirt has, without doubt, the best velcro of any dog product we’ve ever had. That said, it means that you have to practice with it before you need it. I found that I could leave the chest strap connected and just slip it over my pooch’s head. From there it is straight forward providing you have it right side up. It definitely reduced the shaking caused by fireworks. Only gave it 4 stars because I was hoping for magic, but I held my little guy with and without it and it definitely helps.
Benny loves his Thunder Shrit
With quite a few serious thunder storms lately the shirt will help with his anxiety.

I bought this to replace a very old thundershirt. This shirt is essential in helping our Bostie withstand the thunderstorms in our area. The velcro panels allow me to snuggle him up comfortably and it makes him feel more secure.
