Thundershirt design applies a gentle, constant pressure that has a dramatic calming effect for most dogs if they are anxious, fearful or over-excited. The pressure your dog feels from this shirt is going directly to his nervous system which helps calms him down just like when you swaddle a baby.
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.
This product may help improve dogs anxiety from a variety of issues. Issues like: Thunder, Fireworks, the Vacuum Cleaner, Separation, Travel, Crating, Reactive Barking, Visitors, Other Dogs and many more!
