Thundershirt is an excellent treatment for most types of dog and cat anxiety and fear issues.
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’s design applies gentle, constant pressure on a cat’s torso, and this pressure has an amazing calming effect for most cats. Pressure has been used to successfully reduce anxiety for many years for both animals and humans.

Examples include parents swaddling infants, veterinarians using squeeze chutes when vaccinating cattle, and thousands of people with autism using pressure to relieve persistent anxiety.

“We’ve been using Thundershirt at my clinic, and the feedback from our clients is very positive. Thundershirt
is a good alternative solution to try versus medications. And it will definitely ‘Do no harm’.”

“In my experience as a Certified Pet Dog Trainer and dog owner, the Thundershirt can dramatically relieve a dog’s anxieties associated with thunderstorms, fireworks, travel, etc. The even, gentle pressure of the Thundershirt can refocus the dog to a more relaxed, calmer state. Using Thundershirt to relieve the symptoms
of anxiety is a good alternative to medications and at $36, it’s a terrific value.”

Within minutes of putting on his Thundershirt, years of anxiety, aggression, and extreme territorial behavior simply subsided! It is truly amazing. This morning we tried to take it off of him and he got REALLY mad and actually WANTED us to put it back on. Unbelievable!” Tobyhanna, Pennsylvania
