PURPOSE: A body fat analysis device for animal is provided to restrict movement of animal, thereby effectively measuring body fat of the animal. CONSTITUTION: A body fat analysis device for animal comprises: a plurality of electrode materials(110) which respectively include at least one of electrodes for current applications which touch with foot of animals and voltage measuring electrodes； a driving part(120) which controls physical exercise of a plurality of electrode materials in order to interrupt with the movement of the animal； a measuring unit(130) which measures voltage applied in a foot of the animal touching with the voltage measuring electric and applies current in a foot of the animal touching with the electrode for the current application while the electrode material exercises or stops by the driving part； and a body-composition analysis part(140) which calculates bioimpedance using voltage measured from a measuring unit and analyzes body-composition of the corresponding animal from the calculated bioimpedence.본 발명은 동물용 체성분 분석 장치에 관한 것으로, 동물의 발과 접촉하는 전극체의 물리적인 운동을 제어하여 동물의 움직임을 저지시키도록 구현함으로써 동물의 체성분 측정시 동물의 움직임을 효과적으로 제한할 수 있어 보다 정확하게 동물의 체성분을 측정할 수 있도록 한 것이다.
