Thundershirt – Anti-Anxiety Calming Vest for Dogs

The ThunderShirt is the original, vet recommended, natural calming solution that helps reduce anxiety in dogs in a drug-free way.

Like swaddling an infant, the dog anxiety vest’s patented design applies gentle, constant pressure to calm all types of anxiety, fear and over-excitement issues in dogs.

The ThunderShirt helps to calm in over 80% of cases (Based on surveys completed by over two thousand customers, over 80% of dogs show significant improvement in symptoms when using the calming vest). It can be used during thunder, fireworks, separation anxiety, loud noises, travel and vet visits.

Treat anxiety, fear, and over-excitement in style! You’ll love the calming effect on your dog.

A Natural Solution. Unlike with medications, your dog will not be sedated, risk unwanted side effects such as liver or kidney damage, and you won’t be making frequent vet visits for expensive prescription refills. And ThunderShirts are not just for Thunder! Whether you have a rescue dog, a shelter dog, or a new puppy, it can really work to improve your dog’s life and yours.

With its patented design, the Thundershirt uses gentle hugging to calm your dog, applying constant pressure that helps calm most dogs if they are anxious, fearful or overexcited, which leads to:

  • Shaking
  • Hiding or bolting
  • Barking and Panting
  • Licking and chewing
  • Urinating and defecating indoors.

And thousands of veterinarians and trainers agree.
