As written on the American Boxer Club site:

Other breeds have pronounced specialized talents . . . . hunting, herding, trailing, and so on . . . but for a combination of the outstanding virtues of many with the faults of a few, our Boxer is the most gifted of canines. For the man, woman or child who wants an all-round dog, he has no equal. No other dog is more individual in appearance, more keenly intelligent or sanely even-tempered. These virtues alone are priceless if the dog is to become part of his master's family, which he should for the well-being of all concerned. The Boxer has a faculty of worming his way into the good graces and the hearts of an entire household. He seems to offer something special to each person he meets. It's astonishing, but true . . .

The Fascinating Boxer Breed

The Boxer's official classification is the Working Class breed. His keen sense of hearing makes him an instinctive guard dog, always alert. Although always vigilant, the Boxer is not a nervous breed and will not bark without cause. He has an uncanny ability to distinguish between friend and intruder. One of the delightful qualities that sets the Boxer apart is his human-like attempts to "converse," which make his replacement by another breed difficult for one who has owned a Boxer. He mimics the mood of his master and can spend hours quietly lying at his feet.

The Boxer's most notable characteristic is his desire for human affection. Though his spirited bearing, square jaw, and cleanly muscled body suggest the well-conditioned middleweight athlete of dogdom, the Boxer is happiest when he is with people--especially children, watching protectively over their play. His short smooth coat, handsome chiseled head, and striking silhouette never fail to excite comments from passersby as he trots jauntily by your side with neck arched and tail held erect. He is truly a "dog for all seasons," suiting the need for household guardian, attractive companion, and children's playmate and loyal friend.

The Boxer requires very little grooming, and it can easily be done by the owner. An occasional currycombing and/or bath should suffice---the Boxer has a natural tendency to keep himself clean. His neat and tidy coat does not unduly attract dirt.
