The island of Madeira is home to many dogs — and a sizable portion of these animals have been abandoned, are lost, or have always lived on the street. Stray dogs roam the streets, sometimes in packs, and there is no way to know the history or temperament of each dog. In most places on the island, stray dogs are a common sight. Even the University of Madeira had a pack of stray dogs that would settle in various places around the campus. Some workers at the University reported almost being attacked dog packs.


After identifying the problem space, I clarified design goals. How can the island keep better track of its stray dog population and keep the community safe from hostile dogs and dog packs? How can crowdsourcing be used to get lost dogs back to owners? And, how can animal control officials better control the stray dog population by monitoring which dogs are spayed or neutered?


DogTracker is a mobile application that uses long-range RFID scanning to identify and geotag microchipped stray dogs. Dogs who are not microchipped can be photographed, location-tagged, and entered into a database anyone with the DogTracker application. This way, the general population and animal control officials can track the movements of the island’s dog population, avoid dog packs, help control the stray dog population, and help reunite lost pets with their owners.


  • Long-range RFID scanning to identify microchipped stray dogs
  • Crowd sourced reports of stray dogs
  • Easy photo and text reporting of stray dogs
  • Crowd-sourced maps of stray dogs
  • Database of all reported stray dogs, with matching of reports of unchipped dogs
