Boxers trace back to late nineteenth-century Germany, where the Bullenbeisser, a hunting dog that held boar and deer, was crossed with English Bulldogs. The result is a square, muscular dog with a short fawn or brindle coat, often with white markings, a black mask and a blunt muzzle.
A Boxer's clownish, physical affection suits a household that's home often. They stay puppyish for years, so plan on daily exercise, patient reward-based training and supervision around small children who could be bowled over. The short face and thin coat make them sensitive to heat and cold, and the breed carries real heart and cancer risks, so an early vet checkup is wise. Many dogs listed as Boxers are mixes, so size and energy can vary.
