Boxers have earned a slight reputation of being headstrong, which can be related to inappropriate obedience training. Owing to their intelligence and working breed characteristics, training based on corrections often has limited usefulness.
Boxers, like other animals, respond much better to positive reinforcement techniques such as clicker training, which affords the dog an opportunity to think independently and to problem-solve.
Boxers were originally a docked and cropped breed, and this tradition is still maintained in some countries. However, due to pressure from veterinary associations, animal rights groups and the general public, both cropping of the ears and docking of the tail have been prohibited in many countries around the world.
