Using this dog food topper is super easy. Just open the single - serve pouch and pour it over your dog's regular food. For best results, you can mix it well so your dog gets a consistent taste in every bite. Remember, while this topper is great for digestive health, it's meant to be an addition to your dog's main diet, not a replacement. Store the unopened pouches in a cool, dry place. Once opened, if there's any leftover, you can refrigerate it in an air - tight container and use it within a day or two. Keep an eye on your dog's reaction to the new food, and if you notice any digestive issues or allergic reactions, stop using it and consult your vet.
