Hill's Prescription Diet Oncology Care is a dry dog food for dogs undergoing or recovering from cancer treatment. The formula is designed to maintain body weight, lean muscle and appetite during chemotherapy, radiation or post-surgical recovery — periods when many dogs lose interest in food.

High calorie density per cup means dogs can maintain weight on smaller portions when appetite is reduced. Increased protein supports lean muscle preservation against cancer-related muscle wasting (cachexia), and omega-3 fatty acids help modulate the inflammatory response. The recipe is highly palatable to encourage intake during treatment, and antioxidants support overall cellular health.

Vets often prescribe Oncology Care alongside chemotherapy or after major cancer surgery. Owners report improved energy and willingness to eat — small wins that matter enormously when navigating a difficult diagnosis.
