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.

Thundershirt's patent-pending design applies a gentle, constant pressure that has a dramatic calming effect for most dogs.
