A computer program product comprising one or more computer readable storage media and program instructions collectively stored on the one or more computer readable storage media, the stored program instructions executable by one or more computer processors, the stored program instructions comprising:

• program instructions to activate a controller device associated with a first object and a secondary device associated with a second object;
• program instructions to establish a first virtual fence for the controller device and the secondary device, wherein the first virtual fence surrounds the secondary device and the controller device is positioned within the first virtual fence;
• program instructions to receive, from the controller device, a ping with location information for the controller device and the secondary device;
• and
• program instructions to, responsive to determining an adjustment to the first virtual fence is required, adjust the first virtual fence based on a movement of the secondary device from a first location to a second location.
