OBJECTIVE
Dogs are a breed of animals that play important roles in security service, companionship, hunting, guard, work and models of research for application in humans. Intelligence is the key factor to success in life, most especially for dogs that are used for security purposes at the airports, seaports, public places, houses, schools and farms. However, it has been reported that there is correlation between intelligence, body weight, height and craniometry in human. In view of this, literatures were searched on body weight, height and body surface areas of ten dogs with intent to determining their comparative level of intelligence using encephalization quotient.
RESULTS
Findings revealed that dogs have relationship of brain allometry with human as proven by encephalization quotient [Formula: see text] and Brain Mass (E) = kpβ, where p is the body weight; k = 0.14 and β = 0.528, respectively. Saganuwa's formula yielded better results as compared with the other formulas. Dogs with body surface area (BSA), weight and height similar to that of human are the most intelligent. Doberman pinscher is the most intelligent followed by German shepherd, Labrador retriever, Golden retriever, respectively.
目的
狗是一种在安全服务、陪伴、狩猎、守卫、工作和研究模型等方面对人类具有重要作用的动物。智力是成功的关键因素，尤其是在机场、海港、公共场所、房屋、学校和农场等场所用于安全目的的狗。然而，据报道，人类的智力与体重、身高和头盖骨测量学之间存在相关性。有鉴于此，本文对十只狗的体重、身高和体表面积进行了文献检索，旨在使用脑化商来确定它们的智力相对水平。
结果
研究结果表明，狗与人类存在大脑比例关系，这一点可以通过脑化商[公式：见正文]和脑质量（E）=kpβ得到证明，其中 p 是体重；k=0.14，β=0.528。与其他公式相比，Saganuwa 公式得出的结果更好。与人类的体表面积（BSA）、体重和身高相似的狗是最聪明的。杜宾犬是最聪明的，其次是德国牧羊犬、拉布拉多猎犬、金毛猎犬。
