Hill's Science Diet Large Breed Senior with Chicken is a dry kibble formulated for the specific needs of older large-breed dogs. Large dogs age differently to smaller breeds — joints carry more load and metabolism shifts earlier — so the recipe is calibrated for that stage rather than being a general senior food scaled up.

Chicken leads the protein sources, paired with an easy-to-digest ingredient blend aimed at supporting activity levels without overloading an ageing digestive system. Natural glucosamine and chondroitin sources target joint mobility, a balanced mineral profile supports kidney and heart function through the senior years, and omega fatty acids contribute to skin and coat condition. It sits in Hill's Science Diet range, which is formulated with veterinary input.

Owners choose this food when they want a science-led senior diet built specifically around a large dog's frame rather than a one-size-fits-all senior formula. The joint-support component is usually the deciding factor for anyone whose dog is starting to slow down on walks.
