Our calming chews are specifically formulated to aid your dog's shaking & nervousness brought about by loud noises like thunderstorms and unfamiliar situations like large crowds. With regular use, RELAX promotes a healthier and happier pet with all-natural ingredients and a taste your dog will crave. RELAX aims to help your furry friend return to baseline behavior when surprised or out of their routine. RELAX Calming dog supplements promote the production of serotonin and melatonin. Some of the key natural ingredients in RELAX are L-Theanine, Organic Ashwagandha Root, Valerian Root, and Organic Chamomile. Like all supplements, RELAX is best used regularly and isn't an immediate remedy.
