Some of the most important tips when training a boxer are socialization and assertion that the owner is the alpha of the pack. Ensuring a boxer is properly socialized helps puppies grow into more responsible adults and assertion of one's leadership gives them a leader to follow, much like how a wolf pack operates in the wild.
Boxer owners should also start training their dogs from an early age. Boxers are naturally very intelligent, strong-willed and energetic dogs. Starting their training when they are a puppy not only helps strengthen the bond between owner and dog but also gives them a positive outlet for them to expend all of their energy, both mentally and physically. Additionally, this prevents many of the negative traits associated with boxers from ever developing in the first place.
Many owners have taken to using a reward-based training system when training their boxers. This is also sometimes known as positive reinforcement. Boxers do not require a very harsh correction or forceful methods. Instead, whenever a boxer performs in a way the owner approves of, it should be rewarded right at that moment. Praise, in the form of saying "good dog," treats or a special toy are all excellent ways to reward a boxer. Additionally, just spending time with a boxer outside of training helps strengthen the bond between owner and canine, ensuring that the animal feels loved and develops into a responsible adult.
