Boxers trace back to 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 dog with a short, shiny coat in fawn or brindle, often with white markings and a black mask. Boxers have worked as messenger, guard and police dogs.
Many Boxers are clownish, affectionate and physical, and they tend to stay puppyish for years. In Saginaw, that means planning for daily exercise, patient reward-based training and supervision around small children who could get bowled over. Not every dog fits the description, and many shelter "Boxers" are mixes. The breed's short face and thin coat make it sensitive to heat and cold, and heart and cancer risks are real.
