A pet collar is provided with a collar command unit, which may include a stimulator feature for discouraging undesirable behavior and a sensor for detecting the undesirable behavior. A controller in the collar command unit electronically communicates with the stimulator and the sensor. The collar command unit also includes a receiver for receiving an event signal from a remote device, such as a building occupant protection system or cellular telephone, which is indicative of an emergency situation. When the pet exhibits the undesirable behavior, the controller allows the stimulator to deliver a deterrent stimulus. However, when the event signal is received, the controller overrides the stimulator feature, preventing the delivery of the deterrent stimulus to the pet. Additionally or alternately, the collar may include a transmitter for transmitting a response to the remote device and a tracking chip for tracking the location of the pet during or after the event.
