- 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.

Why Does Thundershirt Work?
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.
What Training Is Required For Using Thundershirt For Anxiety And Fear Issues?
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.
Can I Wash And Dry Thundershirt?
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.
How Long Can I Leave A Thundershirt On My Dog Or Cat?
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.
How Do I Put Thundershirt Onto My Dog Or Cat?
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.
Are There Any Special Sizing And Fit Considerations For Male Dogs?
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.
Is Overheating A Concern When Using A Thundershirt?
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.
What If I See Signs Of Discomfort Or Irritation With My Dog Or Cat When Wearing A Thundershirt?
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.

Calm walks at last!
By RuralCashew on Feb 23, 2021
Walks with my 1 year old Lagotto can be stressful for both of us. She tends to lunge and bark at passing cars and bikes that catch her off guard. We have been working SO HARD with counterconditioning, pointing out distractions as they pass and rewarding good behavior, and even talking lower traffic routes, but it's been really challenging. I got her a ThunderShirt and it's like she's a completely different dog! The best way to describe it is that when she wears the shirt, it removes the anxious layer of chaos that made it hard for her to make good choices. I finally feel like our work has been making an impact. I'm so glad that I finally figured out this solution for her!

Adore this product

My baby boy is so much more comfortable with life in general. He had so much anxiety that he would run and hide at the slightest sound. And now he is calm and loving life.

Did nothing for pacing and barking anxiety
By Thundershirt on Mar 1, 2021
This did nothing to help my doberman rescue. The fabric was nice and silky. It was a bit challenging to get on because the velcro sticks to itself on all the flaps. Was a waste of money for me.

Anxiety shirt
By BUGGY on Apr 11, 2021
it's very hard to put on. Confusing and dog gets mad. once on it looks cute but doesn't calm him.

Worked a little bit
By Boschher on Mar 11, 2021
It worked out to start but after the second time using it I wasn't able to use it anymore since my dogs fur was all over the Velcro.

Happy Dogs
By Phoebe on Jan 16, 2021
My products are always delivered promptly. Even the prescription items. The selection is great. I feed many feral cats so I love the cases of 40 canned cat foods offered. The prices can’t be beat! Great company.

Check weight and belly size before ordering.
By Teutankhamen on Mar 11, 2021
Was too small and cut into his armpits. I under estimated his belly girth and size in general.

Stylish as well as functional
By Chica on Dec 5, 2020
Max is 14 mo. old and we’ve used this shirt many times when he gets anxious or can’t settle. Sometimes we leave it on all day. Only comment is that the blue is a really dark blue, almost navy. I had wanted a lighter blue, like it shows in the picture.

Works alright but doesn't fit well
By Brinnysmom on Sep 25, 2020
I think this product reduces anxiety during fireworks in my dog, which is good. The problem I have found is that the way it fits he cannot go to the bathroom while wearing it because the fabric on the stomach area goes down so far. The rest fits well, so I know I bought the right size. Disappointing because I have to take it off for him to go outside where he is most anxious during fireworks (understandably). I also worry about it chaffing and being uncomfortable in his "area." It appears this has happened to a degree. Mixed thoughts.

Thundershirt
By calmingshirt on Nov 13, 2020
The shirt seems good and he didn't complain but my take only, I think the bottom edge is a bit hard and it presses against too close to his penis. I kept pulling it up. I wish it was a bit less long at the bottom, under the stomach.
