Overview
Hill's sizes this 33 lb bag of Science Diet Adult 7+ around one age bracket: dogs seven years and older, with a chicken meal, barley and rice recipe and added antioxidants.
Senior dogs process nutrients differently than younger adults, and Hill's built this formula around that shift with antioxidants aimed at supporting the immune system as dogs age. It sits in Hill's veterinary-style diet line rather than a general all-life-stages formula, and the ingredient list leads with chicken meal rather than fresh chicken.
- 33 lb bag, pellet-form dry kibble
- Formulated for dogs aged 7 and up
- Chicken meal, barley and rice recipe
- Added antioxidants for immune support
Who it's for
Owners of small-breed dogs aged seven and up, looking for a formula tailored to that age bracket. Puppies and younger adults need a different Hill's line.

Performance notes
The pellet-form kibble is built around chicken meal, barley and rice, with antioxidants that Hill's frames as immune support for aging dogs. Hill's also lists benefits around energy, heart health, skin and coat, and lean muscle maintenance, the areas that typically decline first as dogs enter their senior years.
