Question: where does the name boxer dog come from

title: Boxer (dog)
text: Meta von der Passage played the most important role of the five original ancestors . Our great line of sires all trace directly back to this female . She was a substantially built , low to the ground , brindle and white parti - color , lacking in underjaw and exceedingly lippy . As a producing female few in any breed can match her record . She consistently whelped puppies of marvelous type and rare quality . Those of her offspring sired by Flock St. Salvator and Wotan dominate all present - day pedigrees . Combined with Wotan and Mirzl children , they made the Boxer .
