Supports joints & good for gut flora! I bought this "moist dry food" along with the dry food, as it said it was good for joints and gut flora, but it didn't seem to agree with my 5-month-old puppy. It's for adult dogs, but it's supposed to be okay for all stages. It's unopened, but the expiration date is written on the package with the amount. There's no problem with the contents, but please refrain from purchasing if you are concerned! In addition, I will give you puppy and adult wet food as a bonus, which I received from the pet shop☆ If you were interested in Mish One, how about giving it a try?
