The invention discloses a dog-like quadruped robot. The dog-like quadruped robot comprises leg parts, a front shoulder beam, a back shoulder beam, a front vertebral column, a waist part and a back vertebral column, wherein the front vertebral column, the waist part and the back vertebral column mutually form a vertebral column; one end of the front vertebral column is horizontally fixed at the middle part of the front shoulder beam in the form of a cantilever beam; the other end of the front vertebral column is connected with the front end of the waist part; the back end of the waist part is connected with the back vertebral column; the back vertebral column is fixed on the back shoulder beam; the waist part comprises two inflating rubber rods arranged in parallel; the two ends of the two rubber rods extend to form an integrated sheet-like rubber sheet fixedly connected with the front vertebral column and the back vertebral column; the deformation of the rubber rods at the waist part can provide bending freedom degree of the vertebral column in a vertical direction; one inflating rubber rod is connected with a first hydraulic cylinder which is vertically arranged; the first hydraulic cylinder is used for controlling transverse rolling freedom degree of the vertebral column in real time; the other inflating rubber rod is connected with a second hydraulic cylinder which is horizontally arranged; and the second hydraulic cylinder is used for controlling deflection freedom degree of the vertebral column in a horizontal direction in real time. The dog-like quadruped robot disclosed by the invention is advantaged in that the balance of the robot body is easy to adjust; the motion stability of the robot is good and the impact of the robot is reduced.
