Who makes it
Who makes Ol' Roy dog food?
The maker
Walmart private label, MULTI-MAKER. Canned/wet: Simmons (Ol' Roy canned in the 2008 Simmons can-lining withdrawal). Dry: historically multiple co-packers; some Ol' Roy was in the 2018 Big Heart/Smucker pentobarbital recall (now Post lineage), current dry maker not resolved. Do not assume a single maker.
Confidence in this attribution: partial. A co-packer's recall history and quality record belong to every brand it makes, so Ol' Roy's safety profile is Simmons Pet Food's.
