The maker
Who makes this — and how they back it up
The four questions the WSAVA nutrition guidelines tell you to ask a pet-food company. Every answer is sourced or marked as an undisclosed gap — never guessed. This is the "is it made competently?" axis that star-rating sites skip.
Diamond Pet Foods owns and operates its own U.S. plants (Meta MO; Lathrop CA 1999; Gaston SC 2003; Ripon CA 2012; Dumas AR 2016; Frontenac KS 2021), where Diamond Naturals is produced.
source →The source refers to disciplines/experts (veterinary medicine, companion animal nutrition) but does NOT name any specific board-certified veterinary nutritionist (ACVN/ECVCN Diplomate) or PhD nutritionist on staff. Per rules, null.
source →No feeding-trial AAFCO statement found on the 31 labels we’ve verified for this brand, and no company-wide claim was found either. Most pet foods are only "formulated to meet" AAFCO profiles (a paper calculation) rather than fed to real animals in trials — this is common, not necessarily a red flag.
A reproducible PubMed search (author-affiliation field, animal/pet-domain filtered) returns zero indexed papers for this brand name. Not proof no research exists — only that none is PubMed-indexed under this exact name.
