Why does Thundershirt work?
Thundershirt’s patent-pending design is a pressure wrap that applies a gentle, constant pressure on a dog’s torso. From real world experience, we know with certainty that Thundershirt DOES WORK. That is why we are able to offer a money-back guarantee. A survey of Thundershirt users shows that over 80% of dogs show significant improvement in at least one anxiety symptom when using Thundershirt.
According to some experts such as Dr. Temple Grandin, pressure has a calming effect on the nervous system. Using pressure to relieve anxiety has been a common practice for years. For example:
-
TTouch dog trainers use pressure to address a variety of anxieties.
-
Veterinarians use pressure to relax cattle when they are administering vaccinations.
-
Some autistic people use pressure to relieve their persistent anxiety.
Until now, there just hasn’t been a well-designed, inexpensive pressure wrap commonly used for canine anxiety.
Why doesn’t my vet know about this remedy for anxiety and fear issues?
For many types of anxiety… none! Just put Thundershirt onto your dog and you will likely see results with the very first usage. However, for some dogs, it may take two to three usages to see 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? Remove hair from Velcro hooks?
Thundershirt is made with durable, washable fabric. When necessary, Thundershirt may be washed in a regular cycle using regular laundry detergent and warm water. Hang to dry.
If necessary, to remove dog hair from your Thundershirt’s velcro, we recommend using a standard dog “slicker” brush (Available at most any pet store for as little as $2.99). A couple of strokes and the velcro hooks will be nearly completely hair-free.
How long can I leave a Thundershirt on my dog?
Thundershirt is designed to be safe to leave on your dog for extended periods of time when appropriate for the situation or issue that you are addressing. Thundershirt is made out of light-weight, breathable fabric, so over-heating is very rarely an issue. It is typically safe to leave a dog unsupervised while wearing a Thundershirt.
How do I put Thundershirt onto my dog?
We designed Thundershirt to be very easy to put on your dog, even if she is already in a state of anxiety. Click here to see detailed illustrations.
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.

Thundershirt comes in seven different sizes… XXL, XL, L, M, S, XS, and XXS. See the table to find the right size for your dog. Like people, dogs come in many different shapes and sizes, so if your dog has unusual proportions, you may need to go up or down a size versus the “standard” measurements. But the Thundershirt is designed to be very adjustable to accommodate different dog shapes and still be easy to put on.
