Kirkland Signature dog food is made for Costco by Diamond Pet Foods , a large U.S.-based pet food manufacturer that produces food for several other well-known brands as well.

Quick Scoop: Who makes Kirkland dog food?

  • Brand owner: Costco’s in-house label, Kirkland Signature.
  • Actual manufacturer: Diamond Pet Foods, a long-established U.S. pet food company headquartered in Missouri.
  • Where it’s made: Diamond facilities in the United States, including plants in Meta (Missouri), Lathrop (California), and Gaston (South Carolina), among others.
  • Product type: Private‑label dog food (Costco controls the brand and recipes, Diamond handles production).

In short, if you’re buying Kirkland dog food at Costco, you’re getting a Costco brand that’s manufactured by Diamond Pet Foods in Diamond’s U.S. plants.

A bit more context (for curious pet parents)

  • Diamond Pet Foods also manufactures other recognizable brands like Taste of the Wild and various “house” or store-label pet foods, which is why you’ll often see Kirkland mentioned in discussions about good value, mid‑to‑premium dog foods.
  • Kirkland’s positioning is “premium‑style nutrition at warehouse pricing,” so a lot of forum and review chatter in the last few years has focused on it being a budget‑friendly alternative to higher‑priced big‑name kibbles.

Recent chatter and “latest news” angle

  • As of late 2025 and into early 2026, online reviews and pet blogs still describe Kirkland dog food as manufactured by Diamond Pet Foods, with no major change in manufacturer reported.
  • Some long‑time pet owners still bring up Diamond’s older recall history in forum threads, while more recent articles highlight improved quality controls and note that there have been no recent Kirkland‑specific recalls in the last few years.

Multi‑viewpoint snapshot (what people tend to say)

  • Pros:
    • Good ingredient lists for the price, with real meat proteins and formulas that meet AAFCO standards.
* Manufactured in established U.S. plants under shared quality systems with Diamond’s own brands.
  • Cons / concerns raised in discussions:
    • Lingering concern from older recalls tied to Diamond facilities, even though those issues are now dated.
