Thundershirt Heather Gray Dog Anti-Stress WrapWith 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. Data collected from surveys completed by over two thousand customers reveals that over 80% of dogs show significant improvement in symptoms when using Thundershirt. The Thundershirt Dog Anti-Stress Wrap is already helping tens of thousands of dogs around the world, and is recommended by thousands of veterinarians and dog trainers. 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. One of the most common examples is how parents use swaddling to calm an inconsolable newborn infant.Until now, there just hasn't been a well-designed, inexpensive pressure wrap commonly used for dog anxiety. Thundershirt is changing that! Thousands of veterinarians and dog trainers now recommend Thundershirts for their anxiety cases. 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 (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. 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.
