The word “Doge” actually existed before the Kabosu meme.
It comes from Homestar Runner, an early internet comedy/animation series. In June 2005, in a puppet episode called “Biz Cas Fri 1,” Homestar talks to Strong Bad and jokingly spells “dog” wrong:
“That’s why you’re my D-O-G-E.”
Strong Bad responds confused, basically: “Your doge? What are you talking about?”
