Product Overview


For Thunder, Fireworks, Separation, Travel, Barking, Jumping, Training and more. Whenever a dog is anxious, fearful or over excited, Thundershirt’s gentle, constant pressure can bring calm and focus. Thundershirt’s patent pending design applies gentle, constant pressure on a dog’s torso and this pressure has a dramatic calming effect for most dogs. Pressure has been used successfully to reduce anxiety for many years.

Use Thundershirt for:

  • Fear of Thunder 
  • Separation Anxiety 
  • Barking Problems 
  • Any Noise Anxiety 
  • Car or Travel Anxiety 
  • Crate Anxiety 
  • Reactivity 
  • General Fearfulness 
  • Excitability 
  • Leash Pulling 
  • Leash Pulling 
  • General Training Tool 

Thundershirt is an excellent treatment for most types of dog anxiety and fear issues. For many anxieties, we recommend just putting on a Thundershirt and observing the results (Notraining!). You very well may see significant improvement for noise, crate, travel, barking and others with absolutely no training. For more complicated anxiety cases, we recommend using Thundershirt as part of a behavior modification program.
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.

What size is right for my dog?

Thundershirt comes in seven different sizes… XXL, XL, L, M, S, XS, and XXS. See the table to find the right size for your dog. Like people, dogs come in many different shapes and sizes, so if your dog has unusual proportions, you may need to go up or down a size versus the “standard” measurements. But the Thundershirt is designed to be very adjustable to accommodate different dog shapes and still be easy to put on.
