So I thought to myself after seeing the monkey banter Hemmingway was known as "Wax Puppy". Of course I had to look it up.
Apparently Hemmingway got Wax Puppy, then a literal puppy, for Hadley when she was pregnant. Wax Puppy had a curly tail and was very sweet, and was Ernest's favorite until the poor dog died.
Hemmingway wasn't ever the same, and developed a tendency to adopt other dogs that reminded him of his Parisian Wax Puppy.
So now I'm all sad.
