Divide it up in several 2 week supply air tight freezer bags, store half in the fridg and half in the freezer. A 27 pound bag lasts me a little over 2 months.
Problem solved. Unless you want to pay more to buy smaller bags to guarantee freshness.
PS: If you are buying dog food that is loaded with fish oils, check with the dog food company as to if freezing is okay. I have not had any issues. They will probably tell you freezing is not necessary, that the fridg is good enough.
Some oils change when they are frozen, but like I said, I use Zignature and have had no problems.
