The Boxer is also very athletic, making him a great breed for an active person or family. The Boxer also makes a excellent guard because he can be tenacious like a Bulldog. Highly intelligent, the Boxer makes a strong show dog and is perfect for competitive obedience as well. Boxers are considered working dogs. They were one of the first breeds employed as a police dog, and they have been used as seeing-eye dogs. But they are also bred to be companion and guard dogs, perhaps best known for being loyal family pets that are especially fond of children.
