Our take
If your vet hasn't already recommended this, they probably will. Hill's Science Diet Large Breed is the closest thing to a universal vet consensus pick — it's formulated by nutritionists, tested in feeding trials, and built specifically for the joint and weight needs of large dogs.
Purina Pro Plan is what serious dog owners and vets actually feed their own dogs. The large breed formula has glucosamine for joints, real chicken as the first ingredient, and Purina's extensive feeding trial history behind it — hard to beat at this price point.
