Is Purina ONE WSAVA-Approved?
WSAVA does not approve, certify, or endorse any dog food brand. No such list exists. What "WSAVA-approved" actually refers to is whether a manufacturer satisfies the five questions the WSAVA Global Nutrition Committee tells owners to ask. Purina ONE meets all 5, which puts it in the small group of brands that satisfy the full rubric. It substantiates its diets through AAFCO feeding trials, and typically costs $30 – $35 per month for a 50 lb adult dog.

Strengths
- Cheapest brand here that meets all 5 of WSAVA's manufacturer questions
- The current Chicken & Rice label states AAFCO animal feeding tests
- Made in Purina's own US factories, each with an on-site quality assurance lab
- Same Nestlé Purina nutrition staff as Pro Plan, including a board-certified veterinary nutritionist
Watch-outs
- No individual formulator is named for the line
- An older Chicken & Rice label said "formulated to meet" AAFCO profiles, so read the statement on the bag you buy
- Easy to confuse with other Purina lines on the shelf, which differ in formulas and price
Who Purina ONE suits
