The scorecard
WSAVA-aligned criteria
The World Small Animal Veterinary Association's nutrition guidelines suggest questions to ask any pet food maker before you buy. Here are this brand's answers, each with its source, or marked undisclosed when we could not confirm one.
2 of 5 criteria confirmed yes · 0 confirmed no · 3 undisclosed. Undisclosed is common, especially for smaller brands — it means we couldn't confirm an answer from a public source, not that the answer is unfavorable.
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.

No feeding-trial AAFCO statement found on the 25 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.

The cost
What Diamond Naturals costs, against everything else we have priced
The median Diamond Naturals dry food we have priced works out at $1.14 per 1,000 kcal, against $2.17 for the median dry food we have priced — so it sits about 1.9x below the market. Cost per 1,000 kcal is the only basis that survives different bag sizes and moisture levels; per pound this comparison would mean nothing. On composition the gap is usually smaller than the price gap implies: 27.8% dry-matter protein against a median of 32.2%.
