肥胖被认为是狗最常见的营养不良形式之一。评估活狗身体成分的实验室方法包括双能x射线吸收法（DEXA）和氧化氘（D2O）稀释法。临床评估方法包括基于视觉观察、触诊和形态测量的身体状况评分（BCS）。本研究采用这四种方法对23只健康的成年客户犬进行了评估。D2O稀释法测定的体脂百分比（% BF）与DEXA扫描之间存在良好的相关性（决定系数[r(2)] = 0.78）。体脂百分比也可以通过BCS（与DEXA比较，r(2) = 0.92）或通过简单计算的形态计量学测量来估计（与DEXA比较，r(2) = 0.92）。
Obesity is considered one of the most common forms of malnutrition occurring in dogs. Laboratory methods of evaluation of body composition in live dogs have included dual-energy X-ray absorptiometry (DEXA) and deuterium oxide (D2O) dilution. Clinical methods of evaluation include assigning a body condition score (BCS) based on visual observation, palpation, and morphometric measurements. This study used these four methods to evaluate 23 healthy, adult, client-owned dogs. Good correlation (coefficient of determination [r(2)] = 0.78) was found between measurements of percent body fat (% BF) determined by the D2O dilution method and the DEXA scan. Percent body fat can also be estimated using BCS (r(2) = 0.92 comparison with DEXA) or by using morphometric measurements with simple calculations (r(2) = 0.92 comparison with DEXA).
