Mugsy

Mugsy is an American English nickname with early 20th-century slang roots, likely derived from 'mug' meaning 'face' (particularly a comically expressive one) or associated with 'mugger,' someone who makes funny faces. It carries a lovable, street-tough, old-school persona.

Mugsy is a name from another era — it sounds like it belongs to a scrappy little dog in a black-and-white film, the one who always steals the scene. It has that gloriously specific vintage quality of a 1930s New York City nickname, equal parts tough and endearing. The 'mug' connection suits dogs with wonderfully expressive faces — bulldogs, Boston Terriers, pugs — where every emotion plays out in exquisite detail. Mugsy is for the pet whose face is genuinely the funniest thing in your house.
