While it is unknown when the Boxspring originated, the breed was developed from the Boxer and the English Springer Spaniel. The Boxer was created in Germany during the late 19th century. It is widely believed that the breed was established by its ancestor – the Bullenbeisser. The Bullenbeisser was a favorite among the Germans due to its effective talents with hunting bear, wild boar, and deer. Unfortunately, the Bullenbeisser was labelled too slow for hunters and they moved on to faster breeds. In 1897, the Boxer Club was created. In 1904, the Boxer breed was first published. In the 20th century, the Boxer was introduced in the United States. The Boxer became a World War I and II staple after the breed proved to be an outstanding messenger and attack dog. The Boxer ended up coming home with soldiers as a companion. Research suggests that the English Springer Spaniel originated from Spain with the Romans where it was then split in the land Spaniel and the water Spaniel. The breed was eventually split by sizes: the smallest Spaniels became the Cocker Spaniel, the medium Spaniels turned into the Springer Spaniels and the largest Spaniels became the Setters. The Springer Spaniel received its name from its ability to “spring” game. In the 1800s, the Duke of Norfolk bred some of the Springer Spaniels at the time and the breed name was officially adopted in 1900. In 1902, the English Kennel Club recognized the Springer as its own breed. In the 1700s, the breed began to pick up popularity in the United States. In 1910, the English Springer Spaniel was registered with the American Kennel Club. The English Springer Spaniel continues to remain an excellent and popular hunting dog.
