Google Translate says his name in Little Milk Dog. I can absolutely understand why he took / was given that name!

It's not a name per se but more of a slang term or concept, like "little wolfhound". It was mostly born from TV dramas. You can google '小奶狗' or 'xiǎo nǎi gǒu' to find out a little more if you wish but in brief, think of a younger handsome, loyal/obedient guy with a sweet disposition.
