Using this dog food is easy. You can simply pour the contents of the 3 - oz pouch on top of your dog's regular food as a topper, or mix it in well to make the meal more appealing. When storing, keep it in a cool, dry place. Once opened, use it within a day or two and store it in the fridge. Make sure to check the expiration date on the pouch. If your dog has any specific dietary sensitivities, it's always a good idea to consult your vet before starting a new food.
