NOTE: Chronic anxiety is often caused by diagnosed or undiagnosed heart conditions.  Be sure to have your pets heart checked (via Echocardiogram) if they have a chronic anxiety condition. Additionally, this product (as with any holistic product) is not a sedative.  It will not bring your pets energy level below their normal… no supplement should be used in lieu of proper exercise and mental stimulation. Rather, this supplement is designed to be used in addition to exercise, mental stimulation, proper diet (if you feed a kid a candy bar their behavior will be poorer than if you feed them salad), and other supporting factors.
