The State of Pet Food

Most of the price isn't on the label

Everything printed on a dry dog food label — protein, fat, fiber, grain-free, even bag size — explains only 43% of its price. For wet cat food it is 24%. The rest is brand. ¶

Here's how we know. We used a statistical model called a regression. It predicts a food's price from what's actually on the label. Whatever the model can't predict is what you're paying for the name, not the recipe.

50 brands, 24 owners

The 50 pet-food brands in our data trace back to just 24 ownership groups. The top 3 groups make 50.7% of the foods we track. ¶

We connect brands using sourced ownership and manufacturing records — see each brand's page for the receipts.

The same company sells cheap and expensive versions of similar math

Mars sells Pedigree at $1.19 per 1,000 calories and Royal Canin at $3.19 — a 168% gap inside one company (dry dog food, brand medians). ¶

This isn't just Mars. Every maker group with more than one brand shows some version of the same spread — the chart below shows the top 3 groups, cheapest to priciest brand, on the same $-per-1,000-kcal scale.

Every food page on this site now shows its cheapest close label-matches — including ones made by the same company.

The small-bag penalty

Buying the small bag of the exact same food costs a median 49% more per calorie. Half of the 229 foods we checked charge 50% or more extra. ¶

We only compared a food's own smallest bag against its own largest bag, and only when the large bag was at least twice the size — so this isn't different foods, it's the identical recipe in different packaging.

If a food works for your pet, the big bag is the same product at a steep discount per meal. The small bag mostly buys convenience or a trial size, not different food.

Brand premiums, measured

After accounting for everything on the label, Royal Canin dry dog food sells 49% above its label-predicted price. Diamond Naturals sells 39% below. ¶

Every brand's number below is simple: what its foods actually cost, versus what the label math says they should cost. The model holds protein, fat, fiber, grain-free status, and bag size constant.

The same pattern shows up in wet cat food: Royal Canin runs +55%, Friskies runs −62%.

What a word on the bag costs

Foods with "natural" in the recipe name run +25.7% versus their label-predicted price, based on 18 foods. ¶

We measured this the same way as the brand premiums above: the leftover price gap after the label math. Here we grouped foods by a word in the recipe name instead of by brand. We also skipped any food whose brand name contains the word. So this measures the name on the recipe, not the maker.

A word in the name can cost more, or less, or nothing — "wholesome" barely moves the price, and "wild" actually runs a bit cheaper. Only "natural" carries a real premium in our data.

Here's a plainer example of how loose "flavor" words can be: Purina Dog Chow's Dog Chow Complete Adult Beef Flavor Dry Dog Food contains no beef. That's legal — labeling rules only require a flavor to be detectable, not present as a named ingredient (the AAFCO flavor rule). In our data, 1 of 17 flavor-named foods lack the ingredient named in their flavor.

Grain-free costs more — only for dogs

Grain-free dry dog food costs +13.8% more than grain-inclusive. Grain-free dry cat food costs −14.7% — it's actually cheaper. ¶

That's surprising if you assume "grain-free" is a single ingredient story with a single price tag. It isn't — the premium depends on the species and the format, not just the recipe, which means grain choice alone isn't a reliable price signal.

The cat carb gap

Dry cat food runs about 30% carbohydrate with the water mathematically removed, so wet and dry compare fairly (a "dry-matter basis"). Wet cat food runs about 4.6%. ¶

Cats are obligate carnivores — their biology doesn't call for much carbohydrate at all. This is the clearest data argument in the whole corpus for feeding wet food to cats, if that choice works for you and your cat.

The best math in the store

For each segment above, these are the foods whose actual price falls furthest below what their own label composition predicts — the biggest gaps between what the label says and what the food costs. This is not a quality ranking; it says nothing about taste, sourcing, or safety testing. Linked foods route to their full Verified Label page.
