    The ability of the dog to find people and indicate their location is biologically efficient; however, this work suggested that it is possible to increase dog performance by associating it with technology resources. Dogs are trained to search and rescue, working under the supervision of their handlers efficiently. In addition, the handler can identify signs of animal stress or fatigue that may compromise the animal's integrity and thus act to avoid such situations. The goal of this project is to create a wearable device that allows sensing, geolocation, and communication to the search and rescue dog, allowing monitoring the state of health of the animal and increasing its efficiency in rescue operations. This equipment was implemented in a vest designed for dogs, thus characterizing a wearable device (WD). For the design of this equipment a bibliographic survey was done, to detect what is most efficient and modern in terms of commercial modules available in the market, which present appropriate performance to the project objectives. These modules were tested in laboratories to survey the most appropriate configuration parameters. After these surveys, we developed a hardware and software for the integration of these commercial modules and develop devices for the use of the modules in the vest itself, equipped with a camera and sensors, so that the trainer can identify the animal's stress signals through biometric sensors such as electrocardiogram (ECG) and body temperature, allowing the sending of commands to the dog. This vest was attached to the dog in the second phase of this project. Complementing this system, a GPS installed sends location data and digital gas sensors (fuel gas and carbon monoxide) that send danger signals from a certain concentration of them. Therefore, the development of an initial prototype is evaluated and prove the technical feasibility of the system. The animal used for testing does not need to be a trained search and rescue dog; once we did in this first step, the feasibility validation of the systems. This validation was done through tests that was verified in a controlled environment if the developed prototype meets the project requirements, which are the capture of sensors information, geographical location, and online video transmission, besides the ability to receive signals to activate devices of command in the animal vest. In these trials, each of these features was tested quantitatively and qualitatively in a controlled scenario.
