Frequently asked questions

Who makes Diamond pet food?

Diamond is manufactured by Diamond Pet Foods.

Where is Diamond made?

Diamond pet food is made in US.

When was Diamond founded?

Diamond was founded in 1970.

Is Diamond WSAVA-aligned?

Diamond is not on our WSAVA-aligned shortlist. That doesn't automatically mean the food is poor quality — many strong brands haven't pursued WSAVA recognition — but it means we lack independent confirmation of feeding-trial validation and on-staff veterinary nutritionist staffing.

Has Diamond ever been recalled?

No Diamond recall appears in FDA's pet food recall list for the last five years. A recall filed under a parent company's or co-packer's name may not be linked here; FDA's recall list is the definitive source.

How does Diamond score in our analysis?

Diamond averages 54/100 across 31 products in our catalog. Individual product scores combine ingredient quality, AAFCO compliance, and controversial-additive severity. See the methodology page for the full algorithm.
