IRIS USA 22 Lbs / 28 Qt WeatherPro Airtight Pet Food Storage Container with Attachable Casters, For Dog Cat Bird and Other Pet Food Storage Bin, Keep Fresh, Easy Mobility, BPA Free, Smoke

Seems great so far....easy to assemble and seems pretty secure. Hoping my 20# Scottie doesn't figure out how to open this one, especially when it rolls away, just out of her reach, rather than tipping over, and the 'snap on' lid popping off....fingers crossed, LOL! My 95# Lab, would never even consider such an unauthorized entry....such a gentleman!

I got this to keep dog food in a container that is easily accessed and more attractive then a big bag sitting on the floor. It holds over 35lbs. I buy food in 35 lb bags, and there is room for more after I transfer the kibble to the container, so it would probably hold 50lbs. It also has a latch to keep the big dog noses from opening the container and eating on their own. I wanted one with wheels because the bags are heavy to move around, so i can just wheel this around in the kitchen and then store it away when not needed. I have ordered another one for the deck to keep the bird seed dry.
