Our freeze-dried natural dog treats are crafted to last. When you open a bag, aim to use it up within two months to enjoy the maximum flavor and nutritional benefits and make sure to seal it to keep the moisture out, or just pop the treats into an airtight container and they'll stay fresh for up to six months. Unopened, you'll get a minimum of two years of shelf stability with Adventure Dogs Co. treats and toppers. The secret to our treats' longevity is the freeze-drying process, which removes moisture and naturally extends shelf life without the need for preservatives. Just remember to store it in a spot that's cool and dry.
