Nestlé scientists develop algorithm to determine dogs’ biological age for better health tracking

SWITZERLAND – Nestlé scientists have created an innovative algorithm designed to determine a dog’s biological age, a measure that may offer pet owners and veterinarians a clearer picture of a pet’s health and potential longevity. 

The breakthrough, recently published in the journal GeroScience, taps into a vast repository of health data gathered over the last 12 years and provides insights into a dog’s biological age by analysing specific markers, including fasting glucose and kidney function.

Biological age contrasts with chronological age by assessing the body’s overall functional health compared to average levels in pets of the same age. 

While chronological age counts the number of years since birth, biological age considers how lifestyle, diet, and environment impact an animal’s rate of ageing. 

According to Pascal Steiner, Director of Petcare Nutrition at Nestlé Research, the new algorithm has the potential to reveal health conditions that may go undetected through traditional blood markers alone.

Nestlé’s research shows that biological age may serve as a more accurate indicator of a dog’s overall health status than some routine blood markers typically used in veterinary practice. 

Dogs whose biological age surpasses their chronological age often still have “normal” blood markers, which, without biological age insights, could make it difficult for pet owners and veterinarians to detect underlying issues. 

This new metric could offer a proactive tool for identifying potential health risks, enabling timely interventions to improve a dog’s quality of life.

Philipp Gut, an expert in the biology of ageing at Nestlé Research, describes the holistic approach driving this innovation: “This algorithm can equip pet owners and veterinarians with a unique tool to better manage health through a more accurate understanding of aging.”

Nestlé is expanding its personalised pet health offerings with science-backed products like the Petivity powered by Purina PetCare ecosystem. 

This includes smart devices and analysis kits such as the Petivity Microbiome Analysis Kit, which uses pet microbiome data to guide nutrition and supplement choices, and the Smart Litter Box Monitor, which detects changes in cat health by analysing litter box use patterns through AI.

Nestlé’s commitment to integrating predictive health technology with pet care aims to help pets live longer, healthier lives. 

By continuing to develop innovative tools and products, the company hopes to empower pet owners to support their pets through all life stages, enhancing both health outcomes and quality of life.
