Hill's Prescription Diet ONC Care Dry Dog Food, Chicken - Cancer

Our review of Hill's Prescription Diet ONC Care Dry Dog Food finds it best suited for dogs undergoing cancer treatment or needing targeted clinical nutrition; the single biggest reason to consider it is its formulation to support weight maintenance and immune health through highly digestible protein, added omega-3s, and ActivBiome+ technology. This is a veterinary diet developed by Hill's nutritionists and veterinarians to encourage eating when appetite is fragile, making it a practical choice for pet owners working with a clinician to support a dog living with cancer.

Key Features

• Veterinary formulation: Developed by Hill's nutritionists and veterinarians to provide clinical nutrition tailored for dogs fighting cancer.
• Highly digestible protein: Protein sources are designed to be easily absorbed so dogs can maintain strength and daily activity.
• ActivBiome+ technology: Proprietary ingredient technology shown to rapidly activate beneficial gut bacteria and support a healthy GI microbiome balance.
• Flavor-focused recipe: The chicken dry kibble is made to be highly palatable to encourage eating from the very first bowl.
• Immune and weight support: Flavorful fats and essential omega-3 fatty acids help support the immune system and help dogs maintain weight.

Who It's For

Hill's Prescription Diet ONC Care is for dog owners who have been advised by a veterinarian that their pet would benefit from a targeted clinical diet during cancer treatment or recovery.
