How the Thundershirt works

ThunderShirt uses gentle hugging to calm your dog or cat. With its patented design, ThunderShirt’s gentle, constant pressure has a dramatic calming effect for most dogs and cats if they are anxious, fearful or overexcited. Based on surveys completed by over two thousand customers, over 80% of dogs and cats show significant improvement in symptoms when using ThunderShirt. ThunderShirt is already helping hundreds of thousands of dogs and cats around the world and is recommended by thousands of veterinarians and trainers. How does ThunderShirt work? Experts believe that pressure has a calming effect on the nervous system, possibly by releasing a calming hormone like endorphins. Using pressure to relieve anxiety in people and animals has been a common practice for years. Below are several examples.

Parents use swaddling to calm & sooth an inconsolable infant

Wrapping a baby snuggly in a blanket, or “swaddling”, is a very common practice for helping to calm an irritable or upset baby, or to help a baby to fall asleep. Medical professionals today routinely teach swaddling to new parents, and families and friends have been passing down this wisdom for centuries. Some experts believe that swaddling mimics the warmth and pressure babies experience in the womb. But whatever the reason, there is no denying its success!

People with autism use pressure to relieve their persistant anxiety

Many people with autism suffer from persistent anxiety. Dr. Temple Grandin realized that applying gentle pressure around her torso provided wonderful relief for her, and this led to the design of her “Hug Machine”. Now thousands of people with autism routinely use pressure to bring comfort. Over the years, it has also been learned that this kind of pressure can help with a wide variety of behavioral issues for both adults and children. “Pressure Vests” and “Weighted Vests” are routinely used by special needs teachers to provide calming and focus in a wide variety of circumstances.

TTouch trainers use pressure to address a wide variety of animal anxieties

For many years, Tellington TTouch Trainers have been using pressure with dogs and other animals to help with a wide variety of issues, including fear of noises and separation anxieties. Prior to ThunderShirt, they frequently wrapped ace bandages around dogs and cats to achieve this pressure, but this was frequently very difficult to apply and unsafe to leave on an animal when unsupervised. Now most TTouch Trainers are using ThunderShirts because of their ease of use and safety. And ThunderShirts look great! As a component of TTouch Training, ThunderShirt is helping families, veterinarians and trainers increase an animal’s self-confidence, providing comfort in situations that were once frightening or stressful.
