With its patent-pending design, Thundershirt’s gentle, constant pressure has a dramatic calming effect for most dogs if they are anxious, fearful or over-excited. It is this pressure that has a dramatic calming effect for most dogs if they are anxious, fearful or over-excited. From real world experience, we know with certainty that Thundershirt DOES WORK. That is why we are able to offer a money-back guarantee. Based on surveys completed by over 1,000 Thundershirt users, over 85% of dogs show significant improvement in anxiety symptoms when using Thundershirt.

As for WHY Thundershirt’s gentle pressure works to calm a dog, experts such as Dr. Temple Grandin believe that 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 wide variety of anxieties.
  • Veterinarians use pressure to relax cattle when they are administering vaccinations.
  • People with autism use pressure to relieve their persistent anxiety.
  • Children with certain behavioral problems use pressure shirts and weighted vests to relax and focus.
  • Parents use swaddling to calm an inconsolable newborn infant.

Until now, there just hasn’t been a well-designed, inexpensive pressure wrap commonly used for dog anxiety. Thundershirt is changing that! Thousands of veterinarians and dog trainers now recommend Thundershirts for their anxiety cases.

Thundershirt is an excellent treatment for most types of dog anxiety and fear issues. For many anxieties, we recommend just putting on a Thundershirt and observing the results (No training!). You very well may see significant improvement for noise, crate, travel, barking and others with absolutely no training. For more complicated anxiety cases, we recommend using Thundershirt as part of a behavior modification program.

One thing is for certain, for a very large percentage of dogs, Thundershirt’s gentle, constant pressure has a terrific calming effect. This has obvious benefits for most types of anxiety. But Thundershirt is also a very useful tool for managing excitability or hyperactivity with strangers, on the leash, or in a training environment. Thundershirt’s calming effect helps a dog to focus (or refocus) her energies in a more constructive direction, allowing training to be more effective.

Thundershirt is designed to be very adjustable to fit most any sized dog…from the 3 lb Chihuahuas to 100 lb Goldens! The best measurement to use for selecting the correct size is the chest size. See the picture to the right for how to measure chest size. If chest size is not readily available, your dog’s weight may be used as a guideline. We happily accept exchanges if you happen to need a different size.
