An animal artificial limb includes a hollow sleeve, a cushion mat, a non-slip pad and a fixing unit. The hollow sleeve includes a hollow part and a solid part. An accommodation space is formed in the hollow part for accommodating an animal truncated limb. The accommodation space corresponds to an outer diameter of the animal truncated limb. A plurality of openings are formed on a lateral surface of the hollow part. The solid part is connected to the hollow part. A length of the solid part corresponds to a truncation length of the animal truncated limb. The cushion mat is arranged in the accommodation space. The non-slip pad is arranged on a bottom surface of the solid part. The fixing unit is connected to the hollow sleeve for fixing the animal artificial limb to the animal truncated limb.動物義肢包含一中空套筒、一緩衝墊、一防滑墊以及一固定單元。該中空套筒包含一中空部以及一實心部。該中空部內形成有一容置空間用以容置一動物斷肢,該容置空間對應於該動物斷肢的外徑,該中空部之側面上形成有複數個開孔。該實心部連接於該中空部,該實心部之長度對應於該動物斷肢的被截斷長度。該緩衝墊設置於該容置空間內。該防滑墊設置於該實心部之底面。該固定單元連接於該中空套筒,用以將該動物義肢固定於該動物斷肢上。100‧‧‧動物義肢110‧‧‧中空套筒112‧‧‧中空部113‧‧‧開孔114‧‧‧實心部120‧‧‧緩衝墊130‧‧‧防滑墊140‧‧‧固定單元
