This group is a category of solidly built, large dog breeds that all descend from the same common ancestor, the large shepherd dog known as a Molossus. The Boxer is a member of the Working Group. The name 'Boxer' is supposedly derived from the breed's tendency to play by standing on its hind legs and 'boxing' with its front paws. According to Andrew H. Brace's Pet owner's guide to the Boxer, this theory is the least plausible explanation. He claims 'it's unlikely that a nation so permeated with nationalism would give to one of its most famous breeds a name so obviously anglicised'. Other conditions that are less common but occur more often in Boxers than other breeds are hystiocytic ulcerative colitis (sometimes called Boxer colitis), an invasive E. coli infection, and indolent corneal ulcers, often called Boxer eye ulcers.
