What is Canine Biological Age?
While chronological age simply counts the years since birth, biological age measures the wear and tear on a dog's cellular level, reflecting actual health and physical shape.
In veterinary science, biological age is influenced heavily by body condition score (BCS) and daily physical activity. Overweight and obese dogs have higher systemic inflammation, accelerating cellular breakdown. Similarly, dogs with low exercise levels have poorer muscle tone and cardiorespiratory health, causing them to age at an accelerated rate (up to 117%+ of normal speed).
By optimizing your dog's diet and keeping them active, you can decelerate cell breakdown, aligning or even reducing their biological age relative to chronological years.
