The present invention is a system for communicating a voice signal or audio message initiated over potentially great distances and deliverable to an unattended animal, and comprises a base unit and a wireless receiver. Voice signals or e-mail messages incorporating embedded audio files or commands for delivering an audio message are sent over a global communication via computer network to the base unit which includes a transmitter. The transmitter sends via wireless communication the voice signal or an audio message from the transmitter to a local receiver secured to a pet collar or the like. The system transmits live audio signals (converted from the audio files or stored audio messages) in real time over great distances. The receiver is preferably worn on the pet and includes a speaker and wireless receiver for converting the wireless signals sent by the transmitter into audio signals emitted by the speakers.
