Homemade food isn't automatically better than kibble — it's only as good as the recipe, and most recipes fall short.

Checklist: what actually decides this, before you pick a side

• Does the recipe meet AAFCO’s nutrient profiles for adult maintenance or growth? If not, it isn’t complete, no matter how fresh the ingredients are.
• Who wrote the recipe — a board-certified veterinary nutritionist, or a blog, a cookbook, or a well-meaning friend?
• Can you weigh and measure ingredients consistently, or will portions drift week to week?
• Does your dog have a diagnosed condition — kidney disease, pancreatitis, exocrine pancreatic insufficiency — that changes what “balanced” even means for them?
• How much time and money can you actually commit, long-term, not just for the first excited month?

I ask owners to walk through that list before we talk ingredients, because the ingredient conversation is the one that gets all the attention and the completeness conversation is the one that actually determines whether a dog thrives or slowly develops a deficiency nobody notices until bloodwork flags it.

A twelve-year-old dachshund named Biscuit is the dog I still think about when this question comes up. His owner had switched him to a home-cooked diet of ground turkey, rice, and green beans after reading that kibble was “processed” and therefore bad. Biscuit did fine for about eight months — coat looked normal, energy was fine, stool was fine. Then he started losing muscle over his spine and hips, subtle enough that his owner chalked it up to age. The recipe had no calcium source at all. Once we added a properly dosed calcium supplement and rebalanced the recipe against a veterinary nutritionist’s formulation, his muscle condition stabilized over the following months. Nothing about that recipe looked wrong on paper to a non-specialist. That’s the trap.

The nutrient-completeness problem is bigger than most owners expect

This is the part of the debate that gets skipped in favor of talking about “fillers” and “byproducts,” and it shouldn’t be. Commercial kibble that carries an AAFCO adequacy statement has been formulated — and often feeding-trial tested — to hit specific minimums and maximums for every essential nutrient. Home-cooked diets, unless they’re built by or with a veterinary nutritionist, usually aren’t checked against that standard at all.

UC Davis research examining 200 homemade dog food recipes pulled from cookbooks, websites, and pet stores found that 95 percent of them lacked at least one essential nutrient, and the large majority had multiple deficiencies. Only four of those 200 recipes had been written by board-certified veterinary nutritionists — and those four were the ones that came out nutritionally acceptable. That’s a strong signal about where the risk actually sits: not in “homemade” as a concept, but in who designs the recipe.

The FDA is specific about what “complete and balanced” legally means on a label: the food has to pass an AAFCO-recognized feeding trial, meet the AAFCO nutrient profiles for the dog’s life stage, or match a food from the same product family that already has. Kibble that carries that statement has cleared one of those bars. A home-cooked recipe, by default, has cleared none of them — the burden is entirely on the person doing the cooking to hit the same targets, usually without lab access to verify it.

Where homemade genuinely earns its place

I don’t think this settles the argument in kibble’s favor across the board, and I’d be misrepresenting my own practice if I said otherwise. Homemade diets matter clinically for dogs with food allergies where you need to control every single ingredient, for picky eaters who won’t tolerate commercial texture or smell, and for dogs managing chronic conditions where a formulated home diet lets you titrate protein, fat, or fiber more precisely than most retail bags allow. Owners also generally have more control over ingredient sourcing and can avoid a specific allergen entirely, which is harder to guarantee with a mass-produced kibble that may share manufacturing lines.

The tradeoff is real, though. If you switch a senior dog onto a new diet, plan the transition slowly — mixing old and new food over one to two weeks — and read up on how to change food for a senior dog before you start, since older dogs tend to have less digestive margin for error than younger ones. A fast switch, homemade or commercial, is a common reason owners see loose stool and assume the new diet “didn’t agree” with their dog when the real issue was pace.

There’s also a kitchen-safety layer that gets overlooked once someone is committed to cooking for their dog. Home cooks reach for ingredients that are completely normal in a human kitchen and dangerous in a dog bowl — I’ve had two separate calls in the same month from owners who added onions to a homemade batch for flavor, not realizing the risk, and another owner who tossed grapes into a dog’s bowl as a “healthy” mix-in. A commercial diet removes that decision from the owner’s hands entirely; a homemade diet puts it back, which is exactly the point for some owners and exactly the risk for others.

Digestive tolerance doesn’t split neatly along homemade-versus-kibble lines

Owners often assume homemade food is automatically gentler on digestion because it’s “simpler,” and commercial food is automatically harder because it’s processed. In my experience that’s not how digestive tolerance actually sorts. It tracks fiber type, fat content, and how gradually a diet is introduced — not the homemade-versus-commercial label.

For dogs with exocrine pancreatic insufficiency, diet is one part of a three-part management plan. Per a review published in JAVMA, “EPI is treated by pancreatic enzyme replacement therapy, nutritional management (low-residue diets with moderate fat content), and supplementation of cobalamin” — and that same review notes that “future studies are needed to further understand the causes of persistent dysbiosis in animals with EPI following initiation of pancreatic enzyme replacement therapy and assess the efficacy of treatments to ameliorate these abnormalities.” That’s a condition where the diet has to be engineered around a specific deficit, and it’s genuinely easier to control precisely in a home-cooked, veterinarian-guided plan than in most off-the-shelf bags.

Gut microbiome response to diet change is also more individual than owners expect. A peer-reviewed trial in Frontiers in Veterinary Science looking at probiotic response found that “diversity metrics did not distinguish non-responders from responders” — meaning even measurable shifts in gut bacteria didn’t reliably predict which dogs improved. I bring this up because it’s a useful reality check: don’t expect a diet change, homemade or commercial, to produce a uniform digestive result across dogs. Watch your own dog’s stool, coat, and energy over weeks, not days.

The verdict, and what I actually tell clients

I’ve sat across the table from enough owners on both sides of this to know the honest answer isn’t a clean win for either format. A dog eating a properly formulated homemade diet — one checked against AAFCO’s nutrient profiles by a veterinary nutritionist — can do just as well as a dog on a reputable, feeding-trial-tested kibble. A dog eating an unchecked homemade recipe pulled from a blog is at real, measurable risk of a deficiency that won’t show up for months. That’s the actual fork in the road, not “homemade versus kibble” in the abstract.

If you’re set on cooking, don’t wing it: work with a board-certified veterinary nutritionist to formulate or verify the recipe, weigh ingredients on a kitchen scale rather than eyeballing them, and recheck the formulation if your dog’s life stage or health status changes. If a well-formulated commercial diet with an AAFCO adequacy statement fits your dog’s needs and your schedule, it’s a defensible, evidence-backed choice — not a lesser one. Either path can serve a dog well. Neither one does, on autopilot.
