The common claim
What most answers say — and what the evidence supports
Pages that answer 'who makes Kirkland Nature's Domain' consistently say Diamond Pet Foods, and for the dry food that consensus holds up: the 2012 FDA recall named 'Kirkland Signature Nature's Domain Salmon Meal & Sweet Potato Formula for Dogs' among Diamond's recalled dry products, and Costco's own pet FAQ discusses the Nature's Domain grain-free line and states that all of its dry pet foods are made by Diamond Pet Foods. This page covers the dry Nature's Domain food; the Nature's Domain canned/wet products are a separate supply question with their own maker.
Evidence & sources
Every source is graded on the six-tier rubric and archived, so the citation holds even if the original moves or paywalls. The tier badge grades the source; the status grades our confidence in the maker.
Tier 2
FDA recall notice (headed 'Expands Voluntary Recall of Dry Pet Food') lists 'Kirkland Signature Nature's Domain Salmon Meal & Sweet Potato Formula for Dogs' by name among the Diamond Pet Foods dry formulas recalled from its Gaston, S.C. plant — direct co-packer naming for the Nature's Domain dry dog food; it evidences 2012, not the present. Snapshot grepped and verified to contain the Nature's Domain line.
Tier 4
Costco's own FAQ names the 'Nature's Domain Grain Free Dog Foods' line (a dedicated Q&A on their calcium/phosphorus levels) and answers 'Where are the Kirkland Signature Pet Foods made?' with 'All of the dry foods are made by Diamond Pet Foods in five company owned manufacturing facilities, all in the United States.' — the statement covers the Nature's Domain dry foods; verified from the 2025-02-28 snapshot because the live page blocks automated fetches, recheck live at next verification.
