Hill's Science Diet Adult Light is a super-premium dry dog food designed for less active adult dogs that need a lower-calorie diet to reach or maintain a healthy weight. It's an everyday maintenance formula rather than a short-term weight-loss program, and sits in the Science Diet adult range as the lighter alternative to the standard Adult kibble.

The recipe is chicken-based and uses L-carnitine to help support a leaner body condition while quality protein maintains muscle mass. It's calorie-controlled compared to the standard Adult formula and includes omega-6 fatty acids and vitamin E for coat and skin condition, along with the balanced minerals Hill's builds into its adult range. Chicken flavour and quality ingredients are chosen to keep the food palatable even at a reduced calorie density.

Adult Light is often chosen when a dog has started to put on weight with age or reduced activity but doesn't need a prescription therapeutic diet. Because it's formulated for long-term feeding, owners can stay on it past the weight-loss phase to help maintain rather than switching again to something heavier.
