How to choose a pet food container
Updated June 2026Independently researchedNo paid placement.
Choose an airtight container made of food-grade plastic or stainless steel that is appropriately sized for your pet’s food bag, and always store the kibble in its original bag inside the container to maintain freshness and nutritional information.
What material is best for pet food containers?
The most common options are food-grade plastic, stainless steel, and glass. Plastic containers are lightweight, affordable, and widely available, but look for BPA-free versions to avoid chemical leaching. Stainless steel is very durable, does not absorb odors, and is resistant to pests, but it is heavier and can dent if dropped. Glass containers are excellent for small quantities of treats because they are non-porous and easy to clean, but they are too heavy and fragile for large bags of kibble. For most households, a high-quality food-grade plastic or stainless steel container with a reliable seal offers the best balance of practicality and freshness.
How much food should your container hold?
Match the container size to the bag of kibble you typically buy. Common bag sizes range from small 4–8 pound bags up to 35–40 pound bulk bags. Many containers are sold by capacity, often labeled as holding 15, 25, 35, or 50 pounds of food. It is generally best to buy a container that fits one bag at a time, so you are not leaving stale air or old food sitting too long. A slightly larger container is fine as long as the lid seals completely, but avoid oversizing too much because the air gap can accelerate staling.
Should you keep kibble in the original bag inside the container?
Yes, this is a top recommendation from pet nutrition experts. The original bag is designed with a special inner lining that helps preserve the fats and oils in the food, keeping it fresh longer. The bag also carries the expiration date, lot number, and feeding instructions in case of a recall. Simply seal the top of the bag with a clip or fold it over, then place the entire bag inside the container. This way the container acts as an airtight outer barrier while the bag does the delicate work of protecting the food from oxygen and moisture.
What makes a container truly airtight?
Look for a lid that has a built-in silicone or rubber gasket, and a locking mechanism such as snap-locks, latches, or a tight screw-on top. Simple snap-on lids without a gasket usually let too much air in, which can lead to staleness and even insect infestation. A wide mouth opening also helps you scoop food without spilling, and some containers come with a removable scoop that clips to the side. A good seal should feel firm when closed, and you should hear a slight hiss when opening it after a day or two.
How to keep pests and bugs out of pet food?
An airtight seal is the first line of defense. Metal containers have the advantage of being chew-proof, which is important if you have rodents or raccoons in your area. Plastic can sometimes be chewed through by determined pests, so store the container in a secure indoor space like a pantry or cabinet. Additionally, keep the container in a cool, dry place away from direct sunlight and humidity. Some containers are designed with wheels for easy moving, which helps you position them in a spot that is less accessible to bugs.
How to clean your pet food container?
Wash the container with warm water and mild dish soap, then rinse and dry it thoroughly before adding new food. Avoid using harsh chemicals or bleach, as residues can contaminate the kibble. Many plastic containers are top-rack dishwasher safe, but check the manufacturer’s instructions first. For stubborn odors, a paste of baking soda and water left to sit for a few hours can help. Between refills, always give the container a quick rinse and dry. If the seal or gasket becomes worn over time, replace it to maintain an airtight closure.
Frequently asked questions
Can I use any plastic container for pet food?
No, only food-grade plastic is safe for long-term food storage. Look for containers labeled BPA-free and intended for dry goods. Ordinary storage bins or buckets may leach chemicals or not seal tightly enough.
Is it okay to mix old and new food in the container?
It is best to finish the old food completely before adding a new bag. Mixing can lead to uneven freshness and increases the risk of spoilage if the old food has started to go stale or attract pests.
Do metal containers keep food fresher than plastic?
Both can be equally airtight if they have a good seal. Metal is more durable and less prone to absorbing odors or being chewed by pests, but it can dent and sometimes the lids are harder to seal perfectly over time. In general, either works well if kept clean and sealed.
How often should I clean the container?
Clean the container between every new bag of food, which means every few weeks to a couple of months depending on your pet’s eating rate. If you notice a musty smell or any moisture inside, clean it immediately.
What is the best size container for a 35-pound bag of dog food?
A container labeled as holding 40 pounds is ideal for a 35-pound bag because it provides a little extra room without a large air pocket. If the container is too tight, you may have trouble fitting the bag and resealing the lid.
Can I store treats in the same container as kibble?
It is better to keep treats and kibble in separate containers because treats often have higher moisture content and can transfer smells or moisture to the dry food. Many brands offer smaller containers specifically for treats.
