Freeze dried dog food will stay stable stored correctly for years, but it is very expensive.
To @Sam Colt s suggestion of buying a freeze dryer, there is only one place in the country that makes / sells home use units. Your results will be 50/50 on whether or not you get a working machine, and they totally suck at customer service.
Sam has one and it works great, my $4200 experience with them sucked so much I just returned the unit and got a refund. Broke after the first batch of freeze dried food I made.
