Boxers began in late nineteenth-century Germany, where hunting dogs once used to hold boar and deer were crossed with English Bulldogs. The result is a square, muscular dog with a short, shiny coat in fawn or brindle, often with white markings and a black mask. Many shelter dogs labeled Boxers are mixes, so looks alone won't tell you what a dog is.
Most Boxers are affectionate, goofy and physical, greeting people with wiggles and leaps. They stay puppyish for years, so plan on daily exercise and patient, reward-based training. In Killeen, where summers run long and hot, the thin coat and short muzzle matter as much as the energy: a Boxer lives indoors with you, and heart and cancer screening with a veterinarian is part of caring for the breed.
