Boxers trace back to late nineteenth-century Germany, where the Bullenbeisser, a hunting dog used to hold boar and deer, was crossed with English Bulldogs. The result is a square, muscular dog with a short, shiny coat in fawn or brindle, often with white markings, a black mask and a blunt muzzle. Boxers later served as messenger, guard and police dogs.
Many Boxers are clownish and physical, greeting people with wiggles and leaps, and they often stay puppyish for years. In Bartlett, that means planning for daily exercise, patient reward-based training and supervision around small children who could be bowled over. Their short face and thin coat make them sensitive to heat and cold, and the breed carries real heart and cancer risks. Many shelter Boxers are mixes, so size and energy can vary.
