Abstract: A dog train & track system for tracking a pet using a GPS. The system is housed inside a collar made of waterproof material to house all of the components necessary to use and power the system. The software accompanying the collar permits the owner to set boundaries and send a notification to the owner through the software on a computer or smart device in the event the pet leaves the boundary. Furthermore, the system notifies the owner and others in cases were the pet may become distressed. The system may also communicate with a pet door allowing entry into the owner's home using proximity detection within the collar.
