Wet dog food costs roughly five times more than dry kibble to feed the same dog the same number of calories each day. That gap isn’t driven by one single factor. It’s the result of what’s inside the can, how it gets made, how it ships, and what it’s packaged in, all compounding on top of each other.
You’re Paying for Water Weight
The biggest reason wet food costs more per meal is deceptively simple: most of what’s in the can is water. A typical wet dog food is about 75% moisture, while dry kibble sits around 10%. That means roughly three-quarters of every can you buy is water your dog could drink from a bowl for free. When you strip the water out and compare the actual nutrient content, wet food often has more protein gram-for-gram than kibble. But you need to buy a lot more of it to reach the same calorie count, and that adds up fast.
To put real numbers on it, a Tufts University veterinary nutrition team calculated the daily feeding cost for a 55-pound dog needing about 1,100 calories. The range spanned from 55 cents a day on the cheapest kibble to nearly $20 a day on certain wet foods. Even comparing the same brand’s wet and dry lines, the canned version cost about five times more for the same energy intake.
More Meat, Fewer Fillers
Wet food formulas typically contain 25% to 75% fresh or frozen meat, poultry, or fish products. Kibble, by contrast, relies heavily on plant-based ingredients, with commercial extruded dry foods commonly containing 30% to 40% simple carbohydrates from grains or starches, plus additional crude fiber. Those plant ingredients are significantly cheaper per pound than animal protein. When a manufacturer fills a can with chicken thighs, pork liver, or fish instead of corn meal and rice flour, the raw ingredient bill climbs substantially.
This higher meat content is also what makes wet food so appealing to dogs. Organ meats like pork liver and kidney are among the most potent flavor stimuli for dogs, and canned formulas lean heavily on these ingredients to boost palatability. That’s great for picky eaters, but organ meats and whole muscle cuts cost more to source, process, and keep cold before production than shelf-stable grain meals do.
Cans Cost More Than Bags
Packaging is a cost most people don’t think about, but it makes a real difference at scale. A single empty tin can with a pull-tab lid costs manufacturers more than 60 cents. A custom printed stand-up pouch, the kind used for kibble and treats, runs between 15 and 20 cents. That’s a three-to-four-times markup on packaging alone, before any food goes inside. And a large dog might go through two or three cans a day, meaning the container costs pile up in a way that a single 30-pound bag of kibble never does.
Cans are also heavier and bulkier to store and display, which means retailers need more shelf space per calorie of food sold. That inefficiency gets baked into the retail price.
Shipping Heavy Water Is Expensive
Freight costs scale with weight. A case of canned dog food is dramatically heavier than a bag of kibble delivering the same number of calories, because you’re shipping all that moisture along with the nutrients. Dry food can be up to 80% lighter than an equivalent amount of wet food, which means more product fits on a truck for less money. Wet food’s weight increases fuel costs, limits how much a single shipment can carry, and raises handling expenses at every point in the supply chain, from factory to warehouse to store shelf. Those logistics costs flow directly into the price you pay.
Sterilization Replaces Chemical Preservatives
Canned dog food actually contains fewer chemical preservatives than kibble. The canning process itself, which involves high-heat sterilization followed by airtight sealing, destroys bacterial contaminants and prevents oxidation without needing added chemicals. That sounds like a benefit (and nutritionally, it is), but it requires specialized equipment: retort machines that cook sealed cans under pressure, precise temperature controls, and rigorous quality testing for each batch. This thermal processing is more complex and energy-intensive than extruding kibble through a machine and spraying it with a fat coating. The production line moves slower, uses more energy, and demands tighter safety protocols.
The Premium Pet Food Trend
Consumer expectations have shifted the wet food market upward in recent years. The global wet pet food market was valued at $24.64 billion in 2025 and is projected to reach $35.67 billion by 2034, growing at about 4.3% annually. That growth is largely fueled by pet owners who view their dogs as family members and want food that reflects that: real meat, recognizable ingredients, no artificial additives.
Manufacturers have responded by expanding into grain-free, organic, functional, and breed-specific wet formulas. Many now market “human-grade” recipes with ethically sourced proteins and sustainable packaging. These super-premium products sit at the top of the price range, but they also pull the average price of the entire wet food category upward. When the market rewards higher-end positioning, there’s less incentive for brands to compete aggressively on cost.
How to Spend Less on Wet Food
If your dog benefits from wet food (for hydration, dental issues, or just because they won’t touch kibble), you don’t have to go all-in. Mixing a small amount of wet food into dry kibble gives you the palatability boost and extra moisture without the full cost. Many owners use a ratio of roughly 25% wet to 75% dry, which keeps the daily expense much closer to a kibble-only budget.
Buying larger cans instead of single-serve portions also helps, since you’re paying for fewer individual containers per ounce of food. Store opened cans in the refrigerator and use them within three to five days. Shopping by cost-per-calorie rather than cost-per-can gives you a more honest comparison, because a cheaper can with lower caloric density might actually cost more to feed than a pricier, more nutrient-dense option.
