They are always keen to work and play. Boxers need lots of human companionship. They can be rather boisterous and even in old age are still extremely athletic. Teach the Boxer not to be boisterous and especially not to jump up at people. This breed is noted for courage and makes great guard dogs.
Boxers have a wide use in military and police work.
Training should start young and be firm and consistent. This breed requires a dominant owner. An excellent watchdog, the Boxer will restrain an intruder in the same way a Bulldog does. Some major concerns are cardiomyopathy, sub-aortic stenosis, and hip dysplasia. Sometimes prone to epilepsy and stiffness of the spine with advanced age.
