I've never had an issue with the food spoiling, kept inside at normal house temperatures, in the original bag, top folded down and held with a large binder clip so the dogs can't get into it. How long the bag will last will obviously depend upon how much the puppy is eating per day. While yours will come home eating a smallish amount, as (s)he grows, the daily amount will increase somewhat.
If you like doing math and wanted to get a ballpark idea of how long that bag will last, you could look on the bag to see how much each cup of food weighs. For example, one food I feed weighs 79 grams per 8 oz cup, let's call it 80 grams. This 30 pound bag is 13.6 kg or 13600 grams. If you divide 13600 by 80, that means there are about 170 cups of food in the bag, using a standard 8 ounce measuring cup. If a dog eats 3 cups per day, 170 divided by 3= 56. That bag could last about 56 days.
Your 47 pound bag is about 21.4 kg or 21400 grams total. Puppy food is usually denser/heavier than what I have here for my adult dogs, so look on the bag to see how many grams are in each cup. Total grams divided by grams per cup will tell you how many cups are in the bag. Then divide that by the number of cups you'll feed per day to figure out roughly how many days the bag could last. With a growing puppy the amount you feed will increase as their need for food increases but you'll probably still be feeding from that bag for over a month. I haven't found having an open bag for that long is a problem but others may have other experiences.
Ugh- math! Good luck with this!
