I was flipping through The Hanyu Da Cidian when I came across an entry for the word:
the definition is as follows:
and they provide the reference:
﹝毓生﹞却回到屋裏, 拍桌大駡道：‘ 中國 的官這般没信實, 還不如外國的道搿哩。’一個夥計嘴快, 搶着説道：‘掌櫃的, 這話錯了。難道你認得外國的道搿麽？’
Chinese obviously has a word for dog & it's clearly written in Hanyu Da Cidian's definition above: 狗. 道搿 doesn't seem to add anything to the word that isn't already there. The fact that 道搿 exists at all though does show that there must have been some sort of need for a word as such.
What purpose did "道搿" serve?
