Methods, systems, and devices for acquiring data from and communicating with a wearable device (e.g., a collar) affixed to animal are described. A wearable device affixed to a dog, for example, may acquire data and transmit the data to mobile devices or servers using one or several wireless technologies. The wearable device may also receive signaling, which may be indicative of commands to or feedback for the animal wearing the wearable device. The data acquired from the wireless device may be used for monitoring and communicating with an animal by, for example, generating reports, developing training or feeding schedules, or conveying relevant information to animal owners. Likewise, signaling sent to the device may facilitate interaction between an animal and the animal's owner, between the animal and its surroundings, or between multiple animals.
