"Git Along, Little Dogies" https://en.wikipedia.org/wiki/Git_Along,_Little_Dogies
We had to suffer through this song repeatedly in my third grade music class, and it surfaces in my memory occasionally like PTSD. Dogies does not sound like doggies; the first syllable do rhymes with the word so (and the Klingon syllable Do).
Whoopee ti yi yo, git along little dogies!
It's your misfortune and none of my own.
Whoopie ti yi yo, git along little dogies!
You know that Wyoming will be your new home.
Since this is the only context in which anyone remembers the word
dogies nowadays, I have no doubt that Okrand was thinking
about this song when he invented the word.
