Are Dog Food Cans Aluminum? The Truth Behind Your Pet’s Favorite Meal
If you’ve ever opened a can of wet dog food, you’ve probably noticed how light it feels compared to its contents. That’s not just because the food is mostly water—it’s also because the can itself is likely made from aluminum. But are all dog food cans aluminum? And does it really matter what they’re made of?
Let’s be honest: most of us don’t think twice about the packaging our dog’s food comes in. We see the label, check the ingredients, maybe glance at the expiration date, and pop it open. But the material of that can plays a bigger role than you might think—not just in terms of sustainability, but also in food safety, shelf life, and even your dog’s health.
Aluminum has become the go-to material for wet dog food cans for several good reasons. It’s strong, lightweight, and forms an excellent barrier against air, light, and moisture—all of which can spoil food or degrade nutrients. Plus, it’s incredibly efficient to produce and recycle. But like any packaging material, it’s not without its nuances. From the type of lining used to prevent metal contact with food, to how it’s recycled at the end of its life, there’s a lot to unpack.
In this article, we’ll dive deep into the world of dog food can materials. We’ll explore why aluminum dominates the market, how these cans are made safe for pets, what alternatives exist, and how you can make smarter, more eco-conscious choices for your furry friend. Whether you’re a first-time dog owner or a seasoned pet parent, understanding what’s inside—and around—your dog’s food is an important part of responsible pet care.
Why Aluminum Dominates the Dog Food Can Market
Aluminum isn’t just popular in the dog food industry—it’s practically the standard. But why? The answer lies in a combination of practical, economic, and environmental factors that make aluminum the ideal choice for packaging wet pet food.
Lightweight and Durable
One of the biggest advantages of aluminum is its strength-to-weight ratio. Aluminum cans are incredibly strong for how light they are. This means manufacturers can ship thousands of cans across the country without adding excessive weight, which reduces fuel consumption and transportation costs. For pet owners, it also means easier handling—no one wants to wrestle with a heavy, clunky can when their dog is barking for dinner.
But don’t let the lightness fool you. Aluminum cans are tough. They resist punctures, dents, and crushing, which is crucial for maintaining the integrity of the food inside. Unlike glass, which can shatter, or thin plastic that might tear, aluminum holds up well during shipping, stacking on store shelves, and even the occasional drop in your pantry.
Excellent Barrier Properties
Wet dog food is highly perishable. Once exposed to air, light, or moisture, it can spoil quickly, lose flavor, or even grow harmful bacteria. Aluminum provides a near-perfect barrier against all three. It’s impermeable to oxygen and moisture, and it blocks UV light that can degrade fats and vitamins in the food.
This barrier protection extends the shelf life of dog food significantly. Many wet foods can last two to five years unopened, thanks in large part to the airtight seal of aluminum cans. That’s a huge advantage for both manufacturers and consumers—fewer returns, less waste, and more flexibility in storage.
Cost-Effective Production
Aluminum is relatively inexpensive to produce at scale, especially when compared to alternatives like glass or certain plastics. The metal can be rolled into extremely thin sheets without losing strength, which reduces material use and keeps costs down. This efficiency allows pet food companies to offer high-quality wet food at competitive prices.
Additionally, aluminum cans are easy to form into various shapes and sizes. Whether it’s a small 3-ounce can for a tiny Chihuahua or a large 13-ounce can for a hungry Labrador, aluminum can be molded to fit the need. This versatility makes it ideal for the diverse range of dog food products on the market.
Consumer Convenience
Let’s not forget the user experience. Aluminum cans are easy to open—most come with pull-tabs or easy-open lids. They’re also easy to store. Unlike bulky plastic tubs or heavy glass jars, aluminum cans stack neatly in pantries and take up minimal space. For busy pet parents, that’s a big win.
And because aluminum doesn’t absorb odors or flavors, there’s no risk of your dog’s food tasting like last week’s salmon dinner. The metal keeps the food fresh and flavorful until the moment it’s served.
How Aluminum Dog Food Cans Are Made Safe for Pets
Now that we know why aluminum is so widely used, let’s address a common concern: Is it safe for dogs? After all, we’re putting food directly into a metal container. Could harmful substances leach into the food?
The short answer is: not when the cans are properly manufactured. Modern aluminum dog food cans are designed with multiple safety layers to protect both the food and your pet.
The Role of Protective Linings
Pure aluminum can react with acidic or salty foods—like many wet dog foods—leading to off-flavors, discoloration, or even metal contamination. To prevent this, manufacturers line the inside of aluminum cans with a thin, food-grade coating.
For decades, this lining was often made from bisphenol A (BPA), a chemical that raised health concerns due to its potential endocrine-disrupting effects. While studies on BPA’s impact on pets are limited, many pet food companies responded to consumer demand by switching to BPA-free alternatives.
Today, most aluminum dog food cans are lined with epoxy resins, polyester, or other BPA-free materials that are approved by regulatory agencies like the FDA (U.S. Food and Drug Administration) and EFSA (European Food Safety Authority). These linings act as a barrier between the aluminum and the food, preventing any direct contact.
Quality Control and Testing
Reputable pet food manufacturers don’t just rely on linings—they also conduct rigorous testing to ensure their cans are safe. This includes checking for metal migration, seal integrity, and resistance to corrosion. Cans are often tested under extreme conditions (like high heat or long-term storage) to simulate real-world use.
Additionally, many brands voluntarily follow guidelines set by organizations like the Association of American Feed Control Officials (AAFCO), which sets standards for pet food safety and labeling. While AAFCO doesn’t regulate packaging directly, its influence encourages manufacturers to use safe, high-quality materials throughout the supply chain.
Transparency and Brand Responsibility
More and more pet food companies are prioritizing transparency. Brands like Wellness, Blue Buffalo, and The Honest Kitchen clearly state on their websites and packaging whether their cans are BPA-free and what type of lining they use. Some even go a step further by using linings made from plant-based materials or recycled content.
This shift reflects growing consumer awareness. Pet parents are increasingly asking questions about not just what’s in their dog’s food, but what’s around it. And responsible brands are responding by investing in safer, more sustainable packaging.
Aluminum vs. Steel: Are There Alternatives?
While aluminum is the most common material for dog food cans, it’s not the only one. Steel is another metal used in pet food packaging, though it’s far less common. So how do the two compare?
Steel Cans: Stronger but Heavier
Steel cans are typically made from tinplate—a thin layer of steel coated with tin to prevent rust. They’re stronger and more rigid than aluminum, which makes them a good choice for larger cans or products that need extra protection during shipping.
However, steel is significantly heavier than aluminum. A steel can of the same size can weigh up to twice as much, which increases shipping costs and makes it less convenient for consumers. Steel is also more prone to rust if the coating is damaged, though modern manufacturing has largely solved this issue.
You’ll most often find steel cans in bulk or industrial-sized dog food products, such as those used in shelters or veterinary clinics. For everyday household use, aluminum remains the preferred choice due to its lighter weight and lower cost.
Plastic and Glass: Rare but Present
Plastic tubs and glass jars are occasionally used for wet dog food, especially in premium or specialty brands. These materials offer their own advantages—glass is inert and doesn’t interact with food, while plastic is lightweight and shatterproof.
But both come with drawbacks. Glass is heavy and fragile, making it expensive to ship and risky to handle. Plastic, while convenient, can absorb odors and may contain chemicals like phthalates or BPA, depending on the type used. Additionally, plastic isn’t as effective at blocking oxygen and light, which can shorten shelf life.
As a result, plastic and glass are niche options—great for certain products, but not practical for the majority of wet dog food.
The Rise of Sustainable Innovations
The pet food industry is slowly exploring more sustainable packaging options. Some companies are experimenting with recyclable plastic laminates, compostable materials, or even refillable systems. However, these innovations are still in early stages and face challenges in terms of cost, scalability, and performance.
For now, aluminum remains the best balance of safety, functionality, and sustainability. But as technology advances and consumer demand grows, we may see more eco-friendly alternatives in the future.
The Environmental Impact of Aluminum Dog Food Cans
When it comes to sustainability, aluminum has a strong case. But like any material, its environmental footprint depends on how it’s sourced, used, and recycled.
Energy Efficiency in Production
Producing new aluminum is energy-intensive. It requires mining bauxite ore, refining it into alumina, and then smelting it into metal—a process that consumes a lot of electricity. However, recycling aluminum is dramatically more efficient. It takes up to 95% less energy to recycle aluminum than to produce it from raw materials.
This makes aluminum one of the most recyclable materials on the planet. In fact, nearly 75% of all aluminum ever produced is still in use today, thanks to recycling.
Recycling Rates and Challenges
In the U.S., aluminum can recycling rates are relatively high—around 50% for beverage cans, according to the Aluminum Association. However, recycling rates for pet food cans may be lower, partly because consumers aren’t always aware that they’re recyclable or how to prepare them properly.
One common mistake is throwing cans in the trash without rinsing them. Food residue can contaminate recycling streams, leading to entire batches being rejected. Another issue is mixing aluminum with other metals—steel cans, for example, require different recycling processes.
How to Recycle Dog Food Cans Responsibly
The good news? Recycling aluminum dog food cans is easy—if you do it right. Here’s how:
– Rinse the can thoroughly to remove any food residue.
– Remove the paper label if possible (though many recycling centers can process it with the can).
– Check your local recycling guidelines—some areas accept cans in curbside bins, while others require drop-off at a recycling center.
– Don’t crush the can unless instructed—some sorting machines rely on the can’s shape to identify it as aluminum.
By recycling your dog food cans, you’re helping conserve resources, reduce landfill waste, and support a circular economy.
How to Choose the Best Dog Food Cans for Your Pet
With so many brands and packaging options on the market, how do you know which dog food cans are the best for your pet? Here are some practical tips to help you make informed choices.
Look for BPA-Free or BPA-NI Labels
BPA-NI means “BPA non-intent,” indicating that the manufacturer does not intentionally add BPA to the lining. While not all BPA-free linings are created equal, choosing cans with this label is a good first step toward safer packaging.
Some brands go further by using linings made from safer materials, such as acrylic or plant-based polymers. These are often highlighted in marketing materials or on the company’s website.
Check the Brand’s Transparency
Reputable pet food companies are open about their sourcing and manufacturing processes. Look for brands that provide detailed information about their packaging materials, including the type of lining used and whether the cans are recyclable.
Websites, customer service, and even social media can be great resources for this information. Don’t hesitate to reach out and ask questions.
Consider the Can Size and Your Dog’s Needs
Aluminum cans come in a variety of sizes, from 3 ounces to 13 ounces or more. Choose a size that matches your dog’s appetite and feeding schedule. Smaller cans are great for portion control and reducing waste, especially for small dogs or picky eaters.
If you have a large dog or multiple pets, larger cans may be more economical—just be sure to store any leftovers properly in the fridge.
Support Eco-Conscious Brands
Some pet food companies are leading the way in sustainable packaging. For example, brands like Open Farm and Spot & Tango use recyclable aluminum cans and emphasize environmental responsibility in their mission statements.
By choosing these brands, you’re not only feeding your dog well—you’re also supporting companies that care about the planet.
