Overview
Aimed at dogs entering their senior years, this Hill's formula combines chicken meal with barley and rice and is built around the specific nutritional shifts that come with aging, including support for energy levels, heart function, skin and coat, and lean muscle mass.
Hill's also notes it includes added antioxidants intended to support the immune system in older dogs, a common addition to senior-specific formulas. It ships in a 33-pound bag at just under $87, matching the pricing of Hill's other large-format senior lines.

Performance notes
The chicken meal, barley, and rice base is a fairly traditional senior-formula combination, and the added antioxidants are positioned to support immune function rather than address any specific existing condition. As with any senior formula, the value here is in matching the recipe to a dog's actual life stage rather than switching too early or too late.
What buyers say
With 6,889 reviews averaging 4.7 stars and roughly 6,000 bags bought in the past month, this is one of Hill's better-reviewed senior formulas, suggesting consistent results across a large number of households.
When should I switch my dog to a 7+ senior formula?
Most dogs are considered senior starting around 7 years old, though this can vary by breed size. It's worth discussing the right timing with your vet, especially for larger breeds that age faster.
Is this a grain-free formula?
No, it contains barley and rice as part of the recipe. If you need a grain-free senior option, look at Hill's grain-free senior lines instead.
Does this support joint health?
This particular formula is focused more on energy, heart health, and lean muscle support rather than joint-specific care. If joint support is the priority, check Hill's joint-focused senior or large-breed formulas.
