What is boxer? How to use in English

The origin of the word "boxer" dates back to the late 19th century. The term refers to a breed of dog, specifically the German Boxer, which was developed in Germany in the 1890s. The breed was originally called the "Deutsche Boxl" or "German Boxer", with the "boxer" name coming from the dog's distinctive boxing-like stance and movement. When the breed was first introduced to the United States, the name was shortened to simply "Boxer" and was officially recognized as a separate breed by the American Kennel Club (AKC) in 1904. Today, the Boxer is a popular breed worldwide, known for its friendly, energetic, and playful nature. The term "boxer" has also been used as a verb, meaning to engage in a spirited and argumentative conversation or debate, likely due to the dog's feisty and lively personality.
