Using this dog food is easy. You can simply open the 3 - ounce pouch and pour the contents over your dog's regular food as a topper. Or, if you prefer, mix it well with the kibble to give your dog a more homogeneous meal. As for storage, once opened, keep the unused portion in the fridge and make sure to use it within a day or two. When it comes to feeding, always check the feeding guidelines based on your dog's age, weight, and activity level. And remember, while this is a great addition to your dog's diet, it should be part of a balanced diet. Always provide fresh water for your dog alongside the food.
