The dog, named Kabosu, is in “dangerous condition,” her owner Atsuko Sato, a teacher who lives in Japan, shared in a series of Instagram posts this week.Kabosu was diagnosed with acute cholangiohepatitis, a liver condition, and chronic lymphocytic leukemia, a type of blood cancer, Sato shared in a post on Tuesday.The term “Doge” stems from the Flash cartoon “Homestar Runner.” In a 2005 episode, the titular character Homestar calls another character his “D-O-G-E.”More from NBC News Culture & Trends team- Black creators say they 'have to be perfect' to get promotional products from brands.She explained that she usually takes and posts photos of her camera-loving dog to her blog, but never suspected that particular image would make her pet famous.I was terrified at the thought that just one photo I had casually posted on my blog could spread all over the world to places I didn’t know,” Sato said in a statement."
