Additional information (Wiki): Developed in Germany, the Boxer is a breed of stocky, medium-sized, short-haired dog. The coat is smooth and fawn or brindled, with or without white markings. Boxers are brachycephalic (they have broad, short skulls), and have a square muzzle, mandibular prognathism (an underbite), very strong jaws and a powerful bite ideal for hanging on to large prey. The Boxer was bred from the English Bulldog and the now extinct Bullenbeisser and is part of the Molosser group.

Boxers are known particularly for their solitary nature, which can lead them to not being trustful of strangers and other dogs. They get along well with children and the individuals they're habituated with, and trusting of, but can be quite suspicious or uncomfortable surrounded by any animals or humans they don't know.

Boxers are a bright, energetic and playful breed and tend to be very good with children. They are active dogs and require adequate exercise to prevent boredom-associated behaviors such as chewing or digging. Boxers have earned a slight reputation of being "headstrong," which can be related to inappropriate obedience training. Owing to their intelligence and working breed characteristics, training based on corrections often has limited usefulness. Boxers, like other animals, typically respond better to positive reinforcement techniques such as clicker training, an approach based on operant conditioning and behaviorism, which affords the dog an opportunity to think independently and to problem-solve. Because of their resistance to repetitive and punishment-based training, Stanley Coren's survey of obedience trainers, summarized in his book, The Intelligence of Dogs, ranked Boxers at #48 - average working/obedience intelligence. Many who have actually worked with Boxers disagree quite strongly with Coren's survey results, and maintain that a skilled trainer who utilizes reward-based methods will find Boxers have far above-average intelligence and working ability.

The Boxer by nature is not an aggressive or vicious breed, but, like all dogs, requires socialization. Boxers are generally patient with smaller dogs and puppies, but issues with larger adult dogs, especially those of the same sex, may occur. Boxers are generally more comfortable with companionship, in either human or canine form.
