Best Low-Fat Dog Food
15 of 1112 dog foods we've verified come in under 10% fat on a dry-matter basis, ranked cheapest per 1,000 kcal first among the foods we've priced.
"Best" here means "clears every published check below" — not a top-10 pick, not a star rating. 15 of 1112 foods we've verified do (1%). Every one is still ranked by real cost after that.
The rubric
What qualifies a food here
Every threshold below, and its source, published before a single result — the opposite of a star rating. Change a number here and it changes on this food's own product page and the homepage finder too; all three read from the same check.
To qualify, a food must pass:
Fat under 10% (dry-matter basis)
Fat, converted to a dry-matter percentage (removing moisture so kibble and wet food are comparable on one scale), must come in under roughly 10% DM — the ceiling commonly used in veterinary guidance for pancreatitis-prone or fat-restricted dogs.
Source: Computed from the label's guaranteed-analysis fat minimum and moisture maximum — full formula on our methodology page. Unlike the AAFCO growth/calorie thresholds above, this ~10% figure is common clinical practice, not a single official regulatory number.

The results
Foods that qualify, cheapest first
Ranked by cost per 1,000 kcal — priced foods first, then foods we haven't price-matched yet. Cost per day is shown for a reference 40-lb adult dog; use the cost calculator for your own dog's weight.

Why these criteria
What we check, and what we refuse to
A true low-fat prescription diet for pancreatitis is a vet-directed decision, often involving a specific therapeutic formula — this list is a screening tool for the disclosed fat percentage, not a substitute for that conversation, especially for a dog recovering from a pancreatitis episode.
Every check on this site traces to a real, disclosed label field or a computed value with a published formula — never an opinion score. Some common concerns (joint/glucosamine, kidney/renal, heart/DCM-taurine, dental, allergy diagnosis, "holistic" marketing) can't honestly be answered from a label at all, so we never checkmark them — we say so and point you to your vet instead.

Common questions
Best Low-Fat Dog Food, honestly answered
Is 10% dry-matter fat an official AAFCO limit?
No — unlike our weight-management (3,100 kcal/kg) or large-breed-puppy (calcium) checks, which cite specific AAFCO thresholds, the ~10% DM fat ceiling is common veterinary clinical guidance for pancreatitis-prone or fat-sensitive dogs rather than a single regulatory number. We flag that difference on every criteria box.
My dog was just diagnosed with pancreatitis. Is this list enough?
No — talk to your vet first. Dogs recovering from an acute pancreatitis episode are often prescribed a specific therapeutic low-fat diet with tighter fat control than this screening list provides. Use this as a starting point for ongoing management once your vet has weighed in, not as the decision itself.
Why dry-matter basis instead of the label's as-fed percentage?
A wet food's as-fed fat percentage looks much lower than a dry food's simply because wet food is mostly water. Converting both to a dry-matter basis puts every food on the same scale, so this list can fairly include both kibble and canned foods.
