What is a board-certified veterinary nutritionist, and what do DACVN and ECVCN mean?

It is a veterinarian who has completed recognised specialty training in nutrition and passed a specialty college examination. DACVN denotes a diplomate of the US college (ACVN), DipECVCN a diplomate of the European college (ECVCN), each recognised by its respective board (ACVN; ECVCN, EBVS).

What these titles stand for

A board-certified veterinary nutritionist has completed a supervised residency, carried out research and passed a rigorous examination. In the US, the title is DACVN, awarded by the American College of Veterinary Nutrition, part of the ACVIM since 2021 (ACVN). In Europe and the UK, it is DipECVCN, from the European College of Veterinary and Comparative Nutrition, recognised by the EBVS (ECVCN, EBVS). The figure that puts the rarity in context: roughly 100 DACVN diplomates exist in the US and close to 50 ECVCN diplomates in Europe, a tiny pool of specialists for millions of animals.

Why this title makes the difference

These diplomas separate a specialist from a mere formulator or a self-appointed adviser. The WSAVA places the employment of a qualified nutritionist, holding a PhD in animal nutrition or one of these board certifications, at the head of its manufacturer-assessment criteria (WSAVA, 2021). A protected title guarantees a verifiable level of training, unlike unregulated labels such as pet nutritionist, which anyone can adopt.
