Abstract: The invention provides a real-time method and computer-implemented system of monitoring animal health comprising sensing at least one physical characteristic by means of an active physical sensor attached to the animal, and sensing at least one activity of the animal by means of an activity sensor attached to the animal; positioning an active activity signal generator in the environment, such that the activity signal generator is associated with an activity, gathering physical characteristic data and activity data, and wirelessly transmitting all such data to a network receiver/converter, in real-time; converting all such data if necessary, and transmitting all such data over a computer network to one or more users, in real-time.
