Who makes Kirkland Signature Canned (Wet) Dog Food?
No reliable public evidence identifies the manufacturer of Kirkland Signature Canned (Wet) Dog Food as of September 14, 2026.
The common claim
What’s commonly claimed, and what the evidence supports
Most roundup articles that answer 'who makes Kirkland dog food' name Diamond Pet Foods, but that answer comes from the dry food: Costco's own pet FAQ credits Diamond with 'all of the dry foods' only, and Diamond runs limited canning. The single primary-source naming for the canned dog food is historical — a 2007 FDA melamine recall listed the Kirkland Signature Premium Dog canned variety pack among products manufactured by American Nutrition, Inc. of Ogden, Utah (a company since merged into Alphia in 2020). No public evidence identifies who cans Kirkland dog food today, so we log the 2007 maker in the history table and leave the current attribution open.
Evidence & sources
Costco does not disclose its suppliers, and no tier 1–5 source names the maker of this product. Below are the databases and records we checked, and what each one returned.
FDA / FSIS recall database (Kirkland canned/wet dog food, 2008–2026) July 5, 2026
No post-2007 recall names a co-packer for Kirkland canned dog food. The one primary-source naming is the 2007 American Nutrition melamine recall (logged in history[] below); the 2012 Diamond recall was explicitly a 'Recall of Dry Pet Food' and covers no cans.
Costco own pet FAQ (kirkland-signature-pet-faqs.html, 2025-02-28 snapshot) July 5, 2026
Costco credits Diamond Pet Foods with 'all of the dry foods' only; the FAQ is silent on who cans the wet/canned dog food, so the dry attribution does not extend to it.
Costco's manufacturer field / manufacturer-name filter on Costco.com product pages (Wayback CDX) July 5, 2026
No archived Costco canned-dog-food product page exposing Costco's manufacturer field was found; the only archived Kirkland dog-food manufacturer facet ('DIAMOND FEED') is on the dry-food category page. Live costco.com blocks automated fetches — a live product page read still needs a manual browser check.
Trade press / consumer explainers (Krazy Coupon Lady 2024, ConsumerAffairs 2025 roundup, wagwalking, dogfoodadvisor) July 5, 2026
Every 'who makes Kirkland dog food' explainer attributes only the dry food to Diamond Pet Foods; none names a maker for the canned/wet dog food.
ImportYeti (US customs / bill-of-lading) July 5, 2026
No useful Costco import match; canned dog food for a US private label is domestically packed, and Costco masks shipments via freight forwarders, so customs data yields no reliable current co-packer.
Company corroboration — American Nutrition Inc. / Alphia July 5, 2026
American Nutrition, Inc. of Ogden, Utah (the documented 2007 canner) merged with C.J. Foods in 2020 to form Alphia; no source confirms whether the Ogden cannery still packs Kirkland dog food today.
Manufacturer history
An attribution goes out of date when a supplier changes. We date each change and keep the earlier source.
| Period | Manufacturer | What the record says | Source |
|---|---|---|---|
| Present | Not established | Current attribution (unknown). See the evidence above. | Evidence ↑ |
| … → unknown | American Nutrition, Inc. | A 2007 FDA firm recall documents American Nutrition, Inc. (Ogden, Utah) as the canner of Kirkland Signature canned dog food as of 2007 — the recall list includes the 'Kirkland Signature Premium Dog 2-Flavor Variety Pack' and states 'These products represent a small percentage of those manufactured by American Nutrition.' Neither the start nor the end of this co-packing relationship is publicly documented, and American Nutrition merged into Alphia in 2020; the entry records the last verifiable maker of the cans, not a current attribution. | U.S. Food and Drug Administration ↗ |
