WSAVA frames nutrition as a routine vital sign. Its implementation leaflet Easy as 1-2-3 states the practice standard in one sentence: incorporate a nutritional assessment and specific dietary recommendation in the physical exam for every pet, every time they visit.
The "1-2-3" workflow has two levels. The Screening Evaluation: is done for every patient and rests on a short set of elements — Nutritional history/, activity level, Body condition score, and Muscle Condition Score:. Where the physical exam is normal and no risk factors are present, the screening is sufficient. When abnormal findings or nutritional risk factors exist, the clinician proceeds to the extended evaluation (a fuller diet-history, body/muscle condition, and diagnostic work-up). The companion checklist operationalises this: it records Current body condition score* _____/9 and Muscle Condition Score:, and flags the cutoff Body condition score less than 4 or greater than 5 (on 9-pt scale) as a screening risk factor, alongside Snacks, treats, table food > 10% of total calories and other lifestyle/environment items.
Pet-food relevance: this is the practical bridge between an animal's BCS and a concrete feeding recommendation — the layer that turns nutrient science into a per-patient diet plan. Written in paraphrase mode (WSAVA material is copyrighted); exact step labels, element names, and the 4/5 BCS cutoff are anchored verbatim. See also companion_practical_wsava_bcs_dog / _cat.
