The detail

Nulo states it employs two full-time animal nutritionists on staff (nulo.com/our-nutrition). Head of nutrition is Greg Aldrich, Ph.D. (Nutrition, Univ. of Illinois 1995), who established the Kansas State University pet food program and consulted for Nulo for ~14 years before being appointed Chief Operating Officer in Jan 2023 as a 'full-fledged team member' overseeing R&D, product development, food safety and quality control (petfoodprocessing.net; businesswire). The second is Heather Mendoza, Ph.D. (Grain Science & Industry / Pet Food Science, Kansas State). Both hold PhDs relevant to companion-animal/pet-food nutrition, satisfying the WSAVA 'PhD in animal nutrition' bar; hence qualified_nutritionist=staff and who_formulates=credentialed. SUBSTANTIATION: Nulo states its diets meet AAFCO nutrient profiles 'both by formulation and by analysis of the finished product' with no mention of AAFCO feeding trials, so substantiation_policy=formulation-only (the 'by analysis' step is finished-product testing, i.e. QC, not feeding-trial substantiation). QC: Because 100% of production is contract-manufactured by undisclosed co-packers, QC is executed by the co-packer; Nulo CLAIMS 'comprehensive analyses for nutrient content, microbiological integrity, and packaging quality' (nulo.com/our-standards) but does not publish protocols or independent finished-product testing data, so qc=claimed (not documented). PUBLISHES_RESEARCH: set unknown; the head of nutrition has ~90 peer-reviewed academic papers, but these are his KSU/academic output, and there is no evidence Nulo the company funds/publishes peer-reviewed research. TRANSPARENCY: partial. Nulo answers most WSAVA questions publicly (names its nutritionists with credentials, states formulation-based AAFCO substantiation, describes QC intent), but is opaque about its actual manufacturers (declines to name co-packers, citing contracts) and has become LESS transparent over time about where/who makes the food.
