Keeping our pets healthy and happy means not only knowing their age, but also understanding how they are aging. Nestlé scientists have developed an algorithm to determine a dog's biological age and predict its overall health trajectory. Biological age is an important indicator of overall health for both people and pets. This refers to how well the body functions and has aged compared to other individuals or pets of the same chronological age, or age based on birthdate. While we cannot reduce chronological age, factors such as diet, lifestyle habits and environmental conditions can help to improve biological age. Even later in life, a reduction in biological age can lower the risk of disease and increase lifespan. |
