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!
