Our Wellness Calmers offer 20 to 40 minutes of playtime, with the added benefit of natural calming agents such as passionflower, tryptophan, and magnesium to reduce stress during thunderstorms, fireworks, and travel days. Made in small batches in the USA with all-natural ingredients, pups of all shapes, sizes, and ages love our Pops. They're long-lasting, mess-free, and easy to store (no refrigeration required), so take them anywhere!
