An apparatus (200) for controlling an animal or animal positions by applying one or more form of stimulus is disclosed. The apparatus (200) comprises at least one position sensing device (240) that is configured to detect at least one position of at least part of the animal as at least one position value. At least one controller (210) is operatively connected to at least one position sensing device (140). The controller (210) is programmed to read and compare the at least one position value with at least one predetermined value relating to the at least one position for determining if at least one control action is required. The control action relates to transmitting of at least one control signal to the stimulus device (250) to administer at least one form of stimulus to the animal that is able to be sensed by the animal.
