Why we score Optimum Adult Large/Giant Breed Dry Dog Food with Chicken, Rice & Vegetables 15kg 6.2/10
Optimum's Large/Giant Breed formula tailors the everyday recipe to the needs of bigger dogs, with a larger kibble that encourages chewing and high levels of chicken as a natural source of glucosamine for joint support. Prebiotics and antioxidants round it out for digestion and skin-and-coat condition. Worth noting that grains lead the ingredient list ahead of the meat content, which keeps it firmly in the value tier rather than a meat-first premium diet. Still, for owners of larger adult dogs who want a breed-appropriate food without a boutique price, it is a reasonable, Australian-made pick that is easy to find and easy on the budget.
Best for: Adult large and giant breed dogs needing joint-friendly everyday nutrition.
