Boxers are large, muscular, square-headed dogs who look imposing--that is, until you look into their eyes and see the mischief and joy of life reflected there. Because of their playful nature and boundless energy, they are sometimes called the "Peter Pan" of the dog breeds. Boxers aren't considered fully mature until they are three years old, meaning they have one of the longest puppyhoods in the world of dogs.

The typical Boxer is intelligent, alert, and fearless, yet friendly. He's loyal to his family and loves to play with them, but he's also headstrong, especially if you try to use harsh training methods with him.

With minimal grooming needs and legendary patience and gentleness with children, Boxers are great family companions, as long as you provide them with the physical exercise and mental stimulation they need. If you're willing and able to provide them with adequate exercise in the form of walks or runs, they can even adapt to apartment living, so long as they are able to be close to their beloved people.

Boxers originated in Germany and were brought to the U.S. after World War I. Their short, shiny coats are striking: fawn or brindle with flashy white markings. All white or mostly white Boxers are not desirable because genetically, deafness is associated with white coloring.
