A device for restricting a movement of a four-legged animal may include an animal harness, bands, a cord, and an actuator. The animal harness may include neck straps, chest straps, a tubular guide, a back piece, back straps, and two pulleys. The two pulleys may be arranged at respective ends of an elastic cord means, which may be fastened to the animal harness. The bands may be arranged around hind legs of the four-legged animal. The cord may be arranged from each band to the animal harness via the two pulleys. The actuator may be fastened to a forward part of the animal harness and may tighten the cord. Further, the actuator may include an electric motor that tightens the cord. Furthermore, the actuator may be activated by a receiver unit that receives signals from a transmitter unit.
