On a side note. Does storing the dry food in the freezer make a big difference in keeping it fresh?
I always put half in a ziplock back so I'm not opening the whole thing all the time but never thought of using the freezer.
I remember RD did a test of this a few years ago that he posted in a thread somewhere here. He seemed convinced it was helpful so I trust his judgement. I think it didn't matter if you used up the food in a reasonable amount of time.
I also have heard of others here doing it with big containers and just taking out a months supply from freezer. Those giant buckets is where I'd be concerned about quality if you're not able.to use it in a timely manner.
The one food that I wouldn't do it is with NLS probiotics in case the cold killed the probiotic bacteria.
