Schutzhund (/'ʃʊtshʊnt/, German for "protection dog"), currently known competitively as IGP and previously as IPO, is a dog sport that tests a dog's tracking, obedience, and protection skills, and evaluates if a dog has the appropriate traits and characteristics of a good working dog. It was developed in Germany in the early 1900s as a suitability test for German Shepherds, but soon became the model for training and evaluating all five of the German protection breeds, which included Boxer, Dobermann, Riesenschnauzer, and Rottweiler. Though any breed of dog can participate, today the sport is dominated by German Shepherds and the Belgian Malinois breed. Dog owners and handlers participate in Schutzhund clubs as a group activity for training the dogs, and clubs sponsor trials to test the dog
