A companion animal management apparatus and method. The apparatus includes a monitoring and control unit monitoring a behavior of an animal in real-time, a standard data storage unit storing standard data, an owner treatment data storage unit storing owner treatment data, a data comparison unit retrieving real-time monitoring data and determining whether the behavior of the animal is normal or abnormal by comparing the real-time monitoring data to the standard data, a data matching unit retrieving the real-time monitoring data for the behavior obtained by the monitoring and control unit and the owner treatment data. When the data comparison unit determines that the behavior is abnormal, an application unit retrieves and applies the owner treatment data for the real-time behavior. This companion animal management apparatus allows the current behavior to be obtained in real-time and allows the current behavior to be compared with the standard data.
