Frequently asked questions

Who makes Diamond pet food?

Where is Diamond made?

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?

We haven't matched any Diamond products to current FDA recall records. Note that absence of matches isn't a guarantee of no recall history — older recalls may not be in the current feed.
