What does boxer mean?
A boxer is, most commonly, a person who fights competitively in the sport of boxing — an athlete trained to strike with gloved fists within a roped ring. The word carries connotations of toughness, discipline, and courage, and appears frequently in both sports journalism and everyday speech ('a former heavyweight boxer'). A second well-established sense denotes the Boxer, a popular breed of medium-sized German dog known for its muscular build, short coat, and playful, loyal temperament; the name reportedly reflects the breed's tendency to spar or 'box' with its front paws during play. The noun derives from the verb 'to box,' which itself likely comes from the notion of striking with a closed fist. Because both senses are common and clearly distinguished by context — one human, one canine — the word is easy to use correctly, though writers should capitalize it when naming the dog breed in formal prose.
A person who fights professionally or as a competitor in the sport of boxing.
"The champion defended her title against a younger, hungrier boxer."
A breed of medium-sized, powerfully built dog of German origin, having a short coat, a broad blunt muzzle, and a lively temperament.
"Our Boxer greets every visitor with exuberant leaps."
Usually capitalized when referring to the breed in formal writing.
Standard plural for both the athlete sense and the dog sense. Note that 'boxers' alone commonly means 'boxer shorts' (men's underwear), so context matters.
"Two boxers entered the ring to thunderous applause."
Both senses of 'boxer' — the fighter and the dog — trace back to the same idea: something that 'boxes,' whether with its fists or by playfully sparring with its front paws.

Etymology of boxer
The noun 'boxer' derives from the English verb 'to box,' meaning to fight with the fists, which dates back several centuries and likely originated as a colloquial term for striking with a closed hand. The agent-noun suffix '-er' was added to denote one who boxes, first appearing in the context of prizefighting in the eighteenth century as bare-knuckle boxing grew into an organized sport. The dog breed takes its name from the same verb, alluding to the animal's habit of standing on its hind legs and batting at opponents with its forepaws. Related words sharing deeper roots include 'pugilist' and 'pugnacious,' which derive from Latin 'pugil' and 'pugnare' rather than from the Germanic root behind 'box.'
How boxer is actually used
In reference to the dog breed, 'Boxer' is usually capitalized in formal writing, though lowercase is common informally. The sporting sense is neutral in register. 'Boxer' can also appear attributively ('boxer shorts', 'boxer rebellion'), though these compound uses have distinct histories.
