The size

I bought the bigger one with treat storage on top for my husband who takes Care of the 4 legged pets. My husband and I are very pleased. The largest takes care of two dogs food and treats. They are both are made of good quality. This one is used for me. Pat's food. Know top storage containers. No need if you buy bottle cat treats. Thanks chewy

Great air tight. Never had food spoil or smell!

Love this item!! I’ve had this and similar products for a few years and I keep reordering for new uses. I have it for dog food, cat food, chicken feed, and chicken treats (seed/corn/oat blend). I have even donated one to my vet!

Quality! Quiet & Smooth when moving!

Finally after several tries we found the BEST pet food storage solution. Quality made. It didn’t have that horrible smell you get when you normally open a clear container like this. It easily holds 30+ pounds of kibble with room for more. It looks like it might even hold 50 lbs. The wheels went on very easily. Usually you have to really push to get them on. While this really doesn’t matter in our home we are VERY impressed at how easily & QUIETLY it is when moving it across the floor. We have hardwood over a basement making things louder than they really are across the floor. This container glides across the floor easily & quietly.

Food Container

We bought two of these -- one for each dog (they eat different foods). One arrived without a set of wheels, but Chewy took care of the issue. These easily fit a 26 pound bag of dog food while the food is in the bag, which is exactly what we needed. We didn't want to have to dump food out of the bag into a container and worry about oils building up and breaking down in the container. We needed these to help keep pests out of the food and to make getting the bags in and out of the closet where we keep their food easier. These fit the bill with the wheels. As for "airtight", I am not convinced these are truly airtight. The latches are not super secure and I can tug on the lid without using the latch and get it to open very easily. If I push on the lid, I can hear air coming out the edges. I'd venture to guess, however, if you have tiny ants trying to get into your pet's food this may not stop them. Still, we've not had any additional issues with pests, I love the wheeled feature, and that the entire bag of food slides into the container easily.
