Storing food for one dog

[Sheree Parrish]

When I had all of my dogs, (14 at one time), I would buy my complete food in bulk and my freezer was full of meat to add to it. The complete never had time to go stale as a 15kg bag would last a week tops.

Now I am down to just the one, I find I only buy the small, less economical, bags of complete, and the freezer has one drawer dedicated to his frozen meat and fish.  I'm loath to buy the bigger bags of complete as I fear they would go stale before I used them up, I do put his food into an airtight container to keep it as fresh as possible, but just wondered if anyone has any tips on storage if I were to purchase the bigger bags.

Many thanks :-)
