Boxers come from late nineteenth-century Germany, where the Bullenbeisser, a hunting dog used to catch and hold boar and deer, was crossed with English Bulldogs. The result is a square, muscular working dog with a short, shiny coat in fawn or brindle, often with white markings and a black mask. Boxers have served as messenger, guard and police dogs.
Many Boxers are clownish, affectionate and physical, and they often stay puppyish for years. Adopters should plan on daily exercise, patient reward-based training and supervision around small children who could get bowled over. The 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 appearance alone says little about a particular dog.
