Washington Revised Code Title 16. Animals and Livestock § 16.24.230. Moving another's livestock from range

No person shall remove any livestock belonging to another from the range on which they are permitted to run at large, without the prior consent of the owner thereof. The owner of any livestock may move his or her own livestock, together with such other livestock as cannot be separated from his or her own, to the nearest corral, or other facility in order to separate his or her own livestock, if the other livestock are returned to the same location from which they were moved within twenty-four hours.
