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. A survey of Thundershirt users shows that 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…no one knows for sure. There are theories, but no scientific studies to prove them. 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 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.
Until now, there just hasn’t been a well-designed, inexpensive pressure wrap commonly used for canine anxiety.

Thundershirt is changing that!

Thundershirt is designed to be very adjustable to fit most any sized dog...from the 3 lb Chihuahuas to 200 lb Mastiffs! The best measurement to use for selecting the correct size is the chest size. Measure around the chest right behind the front legs. If chest size is not readily available, your dog's weight may be used as a guideline.
