Schutzhund, 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, Giant Schnauzer, and Rottweiler. Though any breed of dog can participate, today the sport is dominated by German Shepherds and the Belgian Shepherd breed. Dog owners and handlers participate in Schutzhund clubs as a group activity for training the dogs, and clubs sponsor trials to test the dogs and award titles. The best dogs can qualify to participate in national and international level championships.

Dog training is a kind of animal training, the application of behavior analysis which uses the environmental events of antecedents and consequences to modify the dog behavior, either for it to assist in specific activities or undertake particular tasks, or for it to participate effectively in contemporary domestic life. While training dogs for specific roles dates back to Roman times at least, the training of dogs to be compatible household pets developed with suburbanization in the 1950s.
