1. Introduction
The Body Condition Score (BCS) is a standardized tool used in veterinary medicine
to assess the body fat and overall health of dogs and cats. It provides a visual and
palpation-based method for evaluating whether an animal is underweight, ideal
weight, overweight, or obese. The concept of BCS has evolved over decades,
becoming an essential aspect of preventive veterinary care, nutritional planning,
and disease risk management (Laflamme, 1997; German, 2006).
Obesity in companion animals has become a major health concern worldwide.
According to the World Small Animal Veterinary Association (WSAVA, 2021),
approximately 40–60% of dogs and cats in developed countries are overweight or
obese. Overweight animals are at higher risk for diabetes mellitus, cardiovascular
disorders, osteoarthritis, and decreased lifespan. Conversely, underweight animals
may suffer from malnutrition, immunodeficiency, and impaired growth.
