The boxer originated in Germany. These dogs are very strong and agile, and can weigh between 50-70 lbs.
Their energetic and playful behavior gives them a label of being headstrong and difficult to train.
Though they are highly energetic, they are not aggressive or violent by nature. They can also appear aloof and unfriendly to strangers.
However, do not make the mistake of messing around with them as it may land you in serious trouble.
The dog may attack you anytime and anywhere, but only in certain circumstances. One of the reasons that makes the dog dangerous is lack of socializing.
One must be extremely cautious when breeding a boxer.
