Boxers were developed in late-1800s Germany from the Bullenbeisser, a hunting dog used to catch and hold boar and deer, 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 broad, blunt muzzle.
Many Boxers are clownish and affectionate, and they stay puppyish for years. Expect a dog that wants to be part of every family routine, plus patient reward-based training and supervision around small children who could be bowled over. Their short faces and thin coats make them sensitive to heat and cold, and the breed carries real heart and cancer risks. Many dogs labeled Boxers are mixes, so a veterinarian visit can help you understand a particular dog's needs.
