The Boxweiler is a hybrid brought about in the 1980s as the result of deliberately crossing Boxers with Rottweilers. Little is known about this cross-breed. What is known, however, is that the parent breeds have long and rich histories.
The Boxer is a Mastiff that comes from Germany. In his 1939 book, The Boxer, John Wagner discusses the history of the Boxer and how it goes back to approximately 2000 B.C. In later millennia, the Boxer's more recent ancestor, the Bullenbeisser (which means "bull-biter" in English) has a significant history as both a bloodsport and a hunting dog. During World Wars I and II, the Boxer was used to carry supplies; British and American soldiers took some of the dogs to their home countries after the wars.
Rottweilers are said to have been around since the first century A.D. and that they came from Roman cattle dogs, eventually making their way into Southern Germany with Roman armies. Several centuries later, in the Medieval period, the Rottweiler became a bear hunter alongside its task as cattle dog. The need for it to be an all-around guard dog — against people, wolves, bears and bulls — has lent to its potent ferocity.
The Boxer was recognized by the American Kennel Club (AKC) in 1904; the Rottweiler was by the AKC recognized a few decades later in 1931.
