With its patent-pending design, Thundershirt’s gentle, constant pressure has a dramatic calming effect for most dogs if they are anxious, fearful or over-excited. Based on surveys completed by over two thousand customers, over 80% of dogs show significant improvement in symptoms when using Thundershirt.
As for WHY Thundershirt’s gentle pressure works to calm a dog, experts believe that pressure has a calming effect on the nervous system. Using pressure to relieve anxiety has been a common practice for years.
The Thundershirt works for dogs with a variety of anxiety issues including:
We recommend just putting on a Thundershirt and observing the results (no training!). 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.
For over 80% 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.
