A quadruped limb protector comprising a plurality of limb covers, a plurality of support members, and a plurality of elastic units. The limb sleeves are spaced apart from each other along the length of the limb and are wearable to the limb. Each of the limb sleeves has a curved section in which the opening is curved forward, and two extensions extending forwardly from opposite sides of the curved section. Each support member spans two adjacent curved segments to support the curved segments and maintain the spacing of the curved segments. Each of the elastic units is disposed between the adjacent ones of the extending sections, and is spaced back and forth from the supporting member, and is elastically deformable and recoverable, and allows the spacing of the adjacent extending sections along the length direction to be changed and restored. The novel can effectively shorten the recovery time required for the muscle strength after the injured limb is restored, and accelerate the recovery to the state before the injury.一種四足動物肢體護具，包含數個肢套、數個支撐件，以及數個彈性單元。該等肢套沿該肢體的長度方向彼此間隔設置，並能穿戴於該肢體。每一肢套具有一個開口朝前地彎曲的彎曲段，以及兩個由該彎曲段的左右兩相反側往前延伸的延伸段。每一支撐件跨接相鄰的兩個彎曲段，支撐該等彎曲段並維持該等彎曲段的間距。每一彈性單元設置於相鄰的該等延伸段間，並與該支撐件前後間隔，且能彈性變形與復原，而允許相鄰的該等延伸段沿該長度方向的間距變化與復原。本新型能有效縮短傷肢復原後肌力所需的復原時間，加速復原至受傷前的狀態。
