Anyone have any thoughts on packaging the pets' foodstuffs the same as you would human food - mylar bags, sealed with O2 absorbers and packed in a can? I did that with 44# of the dogs food and was hoping it would work out. The food is dry dog food, rice and lamb, low in other cereals.
Don't bother with dry dog food this way. Most anything else, sure, but not dog food.
Even the better brands, will have a high amount of fats and oils in it. Fats and oils don't store well.
What we've been doing for years now-
We fill a 55 gallon lid drum with dry dog food. You'll get at least a 2 year rotation out of it. When you open it, the top 1" or so is usually WHITE. That's the fats and oils going rancid. Scoop that part off and throw in the pond for the fish. Dogs CAN eat it but they will make more of a mess in the yard.
We usually rotate around 2 years, I'm sure you could get 3 easily out of it.
Some things don't lend themselves to long term storage very well, dog food is one of them unfortunately.
The canned dog food would probably store as long or longer, but it's expensive and usually not the best to feed to your dogs (as told by a GSD trainer to me).
