Thundershirt is a proven solution for most types of dogs coping with thunderstorm and noise anxiety. And no training is required! Simply slip on Thundershirt and watch the symptoms disappear.

The price of Thundershirt is less than a single visit to the vets, and just one Thundershirt will treat your dog’s anxiety for a lifetime. No drugs or training needed!

Perfect for thunderstorm, noise anxiety, fireworks, vacuum noise or camera flash anxiety. Thundershirt (patent pending) does the following for most dogs suffering from noise anxiety:

1) The physical sensation of wearing Thundershirt distracts the dog from focusing on her fears, and

2) Being wrapped in a Thundershirt gives the dog a feeling of safety and comfort.

Soon after putting on her Thundershirt, your dog will likely settle down and relax. Many dogs will lie down and weather the storms with little to no further symptoms of noise anxiety.

From a more scientific perspective, according to neurobiologists, many types of traumas can cause nerve damage, leading to dogs having exaggerated responses to stimuli such as loud noises. Applying constantly maintained pressure with Thundershirt provides an unchanging, quieting stimulus that allows the dog to relax (in other words, #1 above!).

To determine the right size for your dog, please see the table below. “Chest Size” is the best measurement to use. Simply measure right behind your dog’s front legs where the chest is largest.
