Hill’s Pet Nutrition presented its latest research on microbiome science and new pet nutrition products at the 2025 Veterinary Meeting & Expo (VMX). The company showcased updates to its Prescription Diet and Science Diet lines, emphasizing the role of gut health in overall pet wellness.

“For more than a decade, Hill’s has been at the forefront of microbiome research, recognizing that a healthy gut is foundational to overall pet health,” said Dr. Karen Shenoy, U.S. chief veterinary officer at Hill’s. “Our understanding of the microbiome’s positive impact on everything from immune function to organ health continues to grow, and we are committed to translating our scientific discoveries into nutritional innovations that support veterinarians’ daily clinical practice.”

Advancing gut health through nutrition

Hill’s said its research has led to the development of ActivBiome+ technology, a proprietary blend of prebiotics designed to support digestion, kidney health and overall wellness. The company has upgraded several of its Prescription Diet products to include this technology, including:

• Prescription Diet z/d for dogs and cats, reformulated to help reduce food-related skin and digestive issues.
• Prescription Diet i/d for cats, designed to support digestive health.
• New Prescription Diet i/d for puppies and kittens, formulated for young pets with digestive sensitivities.
• New Prescription Diet Multi-Organ for dogs and cats, developed for pets with multiple health conditions.
• New Prescription Diet Brain Care + j/d, supporting cognitive function and mobility.

Hill’s has also updated its Science Diet dry dog and cat foods with ActivBiome+ Multi-Benefit technology to promote digestion, immune health and overall vitality.

“Every meal is an opportunity to enhance the health and well-being of pets,” said Dr. Shenoy. “At Hill’s, veterinary professionals are at the heart of all we do, and we stand as their partners in pioneering new and improved, innovative nutrition that helps them best meet their patients’ evolving needs. Our newest advancements in microbiome science, support for pets with concurrent conditions, and lifestage nutrition are extensions of our commitment to enriching pets’ health, every step of the way.”
