The Thundershirt’s gentle, constant pressure has a dramatic calming effect for most dogs if they are anxious, fearful or over-excited. It can be used to help with noise anxiety, separation anxiety, travel anxiety, crating, barking and many other uses. 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 Thundershirt’s for their anxiety cases.
