Overview
Purina ONE Plus Large Breed Adult is a dry chicken formula in granule form, sold in a single bulk bag. It adds glucosamine and antioxidants and leaves out artificial colors and flavors.
Joint support matters most in big dogs, and the glucosamine and high protein recipe is aimed squarely at that need. The limitation is the chicken base and the adult-only age range, with no calorie figures in the listing.
Who it's for
A home with a big adult dog will get through a bulk bag, and the large breed targeting suits that feeding level. Owners of small breeds, puppies or dogs with chicken allergies should look at a different recipe.
Pros and cons
- Glucosamine for hip and joint support
- High protein formula
- No artificial colors or flavors
- Made for large breeds
- Adult age range only
- Calorie content not listed
Performance notes
Glucosamine is the ingredient the listing ties to hip and joint support, and the high protein content supports muscle. Because the kibble is a granule, feeding amounts have to be set by dog weight and activity, and the listing gives no feeding chart.
