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 more than 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?

Good question! With millions of dogs suffering from anxiety, it amazes us that such an easy to use, inexpensive solution like Thundershirt isn't more widely known and used. Thundershirt is working to change that; we have launched an outreach campaign for veterinarians. If you would like us to speak with your veterinarian, please contact us.

What training is required for using Thundershirt 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.

What if Thundershirt isn't working for my dog?

We stand behind our product! Thundershirt is a terrific solution for most dogs suffering from anxiety. Many owners see reductions or complete elimination of symptoms with the very first use. With others, it may take two or three usages of Thundershirt to see results.

But if for any reason Thundershirt isn't the right solution for your dog, return it within 45 days for a full refund of your purchase price (less Shipping and Handling). See the FAQ below for detailed return or exchange instructions.

Can I wash and dry Thundershirt? Remove hair from fastener hooks?

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.

If necessary, to remove dog hair from your Thundershirt's fastener hooks, 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 fastener 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. When properly sized and properly put on with a comfortably snug fit, your dog should be very comfortable for extended periods. It is typically safe to leave a dog unsupervised while wearing a Thundershirt. If you will be allowing your dog to wear a Thundershirt for extended periods (e.g. over 2 hours), during the initial periods, we do recommend removing the Thundershirt frequently to check for any signs of irritation points. Irritation points are very rare, but best to be cautious.

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. See detailed illustrations near the end of our image galleries.

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.

What size is right for my dog?

Size    Chest Size    Weight
XXS     9"-13.5"       < 7 lbs.
XS      13"-18"         8-14 lbs.
S        16"-23"        15-25 lbs.
M       18"-26"         26-40 lbs.
L        24"-32"        41-64 lbs.
XL      31"-40"        65-110 lbs.
XXL    38"-50"        > 110 lbs.

Measure 'Chest Size' at the broadest part of the animal's torso (behind the front legs). Click here for a graphic showing how to measure your pet.
Thundershirt comes in seven different sizes: XXL, XL, L, M, S, XS, and XXS. See the table above 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.

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. The state of Florida is one of our biggest markets. 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.
