i have 3 different containers i bought at different times. the first was just a plastic container called airtight container. its cheap plastic and i got it at petsmart i think. then i needed another when my dogs were on separate food so i got a tall skinny one called a rubbermade scoop and go. it holds 34 pounds of food. its a good one and has a scoop with it. i got it at petco. next i decided to try this other one as it was airtight and supposedly thats the way to go with storing dog food not in a bag. this one is a gamma food vault or some thing and its a small square cube that has a lid that screws on so its airtight. very small and compact and holds 25+ pounds. i got it at petco to. i love my last 2 and esp the vault one but in the space you have i think the rubbermaid one would be better. i dont see it listed on the petco website but maybe check the store.
