Most people say that their dogs really enjoy wearing their ThunderShirt and they are safe to leave on for extended periods of time, depending on the issue. But, please note! We recommend removing ThunderShirt every one to two hours the ﬁrst few times to be sure everything is ﬁtting correctly and your dog is comfortable.
Irritation or other issues are very rare, but it’s always best to be cautious.
Always remove ThunderShirt at least twice a day if using for extended periods.
