Homemade sounds healthier. It’s often not balanced.

Fresh chicken, rice, and vegetables look healthier than a bag of kibble. A 2025 study of over 1,700 homemade dog food recipes found that only 6% actually met basic nutritional standards.

Homemade dog food has a real appeal — visible, recognizable ingredients, control over sourcing, no unpronounceable additives. What that appeal obscures is that “real food” and “nutritionally complete food” are not the same thing, and getting a dog’s diet balanced correctly on paper takes more precision than most home recipes achieve, even well-intentioned ones built from reasonable-sounding, genuinely wholesome ingredients.

It’s not that homemade food is inherently worse than commercial food. It’s that “complete and balanced” is a formulation standard, not a description of how healthy the ingredients look.

Quick answer: A large 2025 study found only about 6% of owner-submitted homemade dog food recipes met basic AAFCO nutritional standards — most commonly falling short on calcium, phosphorus, and trace minerals. If you’re feeding homemade long-term, work with a board-certified veterinary nutritionist to formulate the recipe, follow it exactly with no substitutions, and don’t treat any ingredient — especially a calcium supplement — as optional.

What the Research Actually Found

These weren’t recipes assembled carelessly — most included meat (90%), vegetables (65%), and nearly half of owners reported adding a commercial food or topper alongside the homemade portion. The gap wasn’t effort or intent; it was that balancing a recipe to meet a dog’s actual nutrient requirements takes more precision than “this seems like a healthy mix of real food.”

Why This Is Easy to Get Wrong Even With Good Intentions

Part of what makes this research notable is that it wasn’t studying obviously careless feeding — it was studying recipes owners had put real thought into, often built around ingredients that read as thoughtful and healthy: named protein sources, fresh vegetables, no artificial additives. The researchers’ point wasn’t that these owners were being negligent; it was that “looks healthy” and “is nutritionally complete” are evaluated completely differently, and only one of them can actually be checked by eye. A recipe can look, smell, and even perform well in terms of coat and energy in the short term while still running a slow nutrient deficit that only shows up as a health problem months or years later — which is part of why these gaps go unnoticed by owners who feel their dog is doing fine.

Why Calcium Is the Ingredient Most Likely to Break a Recipe

Left uncorrected over time, this imbalance can lead to real skeletal problems — including a condition informally called “rubber jaw,” where bone tissue softens and weakens — along with broader bone health issues and kidney strain. The frustrating part, according to the researchers behind the 2025 study, is how easy this is to trigger by accident: leaving out a calcium supplement because it seems like a minor add-on, or swapping one oil for another, can shift a previously balanced recipe out of range without the food looking, smelling, or tasting any different to the dog eating it every day.

“Nothing Is a Filler” — Why Substitutions Are the Real Risk

The researchers behind the Texas A&M study were specific about this point: in a properly formulated homemade recipe, no ingredient should be treated as optional or swappable based on what’s in the fridge that day. A different oil changes fatty acid ratios. A different vegetable changes fiber and micronutrient content. Skipping “just this once” on a supplement, repeated often enough, adds up to a real deficiency over months of feeding. This is the opposite of how most home cooking works — where substitution is normal and expected, even encouraged as creativity — which is exactly why treating a dog’s recipe with that same casual flexibility is the most common way a technically-correct recipe drifts into an actually-incomplete one over time.

What a Properly Balanced Homemade Diet Actually Requires

Ingredients to Avoid Regardless of the Recipe

Separate from the balance question, some homemade-diet ingredients carry outright safety risks: grapes and raisins (linked to acute kidney injury, with no established safe dose) and whole bones (real risk of tooth fracture, gastrointestinal perforation, or obstruction requiring emergency surgery). These aren’t nutrient-balance issues to formulate around — they’re ingredients to leave out of a homemade recipe entirely, regardless of how a particular formula treats them or what a well-meaning recipe found online might suggest.

Higher Stakes for Puppies and Dogs With Existing Conditions

An imbalanced homemade diet is a bigger risk for a growing puppy, whose skeletal development depends heavily on getting calcium and phosphorus ratios right during the growth window, and for any dog already managing a chronic illness, where a nutrient gap can worsen an existing problem rather than just falling short of an abstract ideal. For these dogs specifically, professional formulation isn’t a nice-to-have — it’s the difference between homemade feeding being a reasonable choice and a genuinely risky one.

Commercial “Complete and Balanced” Isn’t Marketing Fluff

It’s worth understanding what that label actually means, since it’s easy to dismiss as boilerplate: a commercial food labeled “complete and balanced” for a specific life stage has been formulated to meet AAFCO nutrient profiles, either through recipe formulation against those published standards or through actual feeding trials. This doesn’t mean every commercial food is equally well-made — quality and ingredient sourcing still vary considerably between brands and price points — but it does mean the basic nutrient math has been checked against a standard, which is precisely the verification step that’s missing from the vast majority of home recipes in the research above. A homemade diet can absolutely meet or exceed that same bar, but only when it goes through equivalent formulation rigor, not just careful, well-intentioned ingredient selection.

A Middle Path: Commercial Base With Homemade Additions

For owners who want some homemade element without taking on full formulation responsibility, a reasonable middle option is using a complete commercial food as the nutritional base and adding small amounts of homemade “toppers” — a spoonful of plain cooked vegetables, a small portion of lean cooked meat — that stay under roughly 10% of total daily calories. At that proportion, minor imbalances in the homemade portion have limited ability to meaningfully skew the overall diet, since the commercially balanced base is still doing the nutritional heavy lifting. This isn’t the same as a fully homemade diet and doesn’t require the same nutritionist-level precision, making it a lower-risk way to add variety and homemade appeal without recreating the calcium-and-trace-mineral problem the research above keeps turning up.

Homemade doesn’t automatically mean healthier.
It means “as balanced as the recipe behind it” — and most recipes aren’t.

Where to Actually Find a Veterinary Nutritionist

Board-certified veterinary nutritionists are a smaller specialty than many owners expect, and not every general practice has one on staff — the American College of Veterinary Nutrition maintains a public directory of board-certified diplomates, and many offer remote consultations specifically for recipe formulation, which makes this accessible even outside a major metro area. Your regular vet can also facilitate a referral directly, and some veterinary teaching hospitals run dedicated nutrition consultation services worth asking about if a diplomate isn’t available locally.
