#1 Boxers are intelligent and respond very well to rigorous yet cheerful training.
They also have an independent streak and don't like being bossed around or being treated roughly. You will have the greatest possible training success if you make the lesson a game for him.
#2 Some boxers take their guard duty a little too seriously, while others show no guard instincts at all.
#3 To get a healthy dog, never buy from an irresponsible breeder, a mass breeder, or a pet store.
Look for a reputable breeder who tests their breeding dogs to make sure they don't have any genetic diseases that could be passed on to the puppies and that they have a solid temperament.
