Notes: “Large‑breed” recipes typically adjust calcium/phosphorus, energy, protein and joint‑support nutrients (glucosamine/chondroitin) and use larger kibble sizes. Availability and exact formulations vary by country and retailer, so check the product label or the brand’s local site for the specific life stage and size target before buying.
