History
From ancient Germany precisely around the 19th century had the now extinct mastiff breed Bullenbeisser and bulldogs brought in from England. At the time of their arrival, they served as hunting dogs for bears, deer, and other ferocious beasts, it would capture the prey with the help of its awesome teeth and detain it until the hunter arrives.
Sometime later these dogs were crossbred to produce what we have today as the resilient “Boxer” and in 1894, some Germans began to test its popularity in dog shows which gave place for the first boxer club (the Deutscher) in 1896. And in 1904 the first boxer standard club was launched with a comprehensive document that is still in use today.
Shortly after, the breed made its way into other European countries and got into the U.S in the late 19th century with the American Kennel Club taking registration of its first boxer around 1904.
During the first world war, boxers played the role of a military dog as a pack-carrier, a guard dog, and an attack dog, later they were taken home by the soldiers and got introduced into the domestic world as a show dog, best companion, and a reliable guard.
