These large portable pet food containers are produced using only food approved materials. The large food container can hold approximately 33 lbs (15 kg) of our dry food. The 4 wheels enable you to move the container to anywhere you need it as easily as possible. The lid uses special sealing to ensure it is air tight to keep your furry friend's food as fresh as possible. The scoop attaches easily to the inside of the lid so you can always find it at dinner time!
