Like your weird little cousin got pushed to 5th grade because his teacher would rather die than deal with him for another 10 months, Petunia graduated from puppy middle school
She did not try very hard at all, and spent most of her time in class making eyes at the teacher's husband, who she would willingly die for if he asked
JK she actually learned real cool stuff like how to actually take a break and settle down in one spot instead of losing her friggin mind on the daily
She got a pupcake for being so smart and beautiful and strong
The Hound says that the training "didn't do shit, Susan" but he's just a curmudgeon who didn't get a pupcup and a new celebrity crush
She has been given at least 14 new nicknames, including Tood The Dood, The Great Toodly-Doodly, Looney Toon, Tunafish, Tuna, Fish, and my personal favorite, "THE THING"
She proved that she is actually very good at the learning part of training - she just expects fair and reasonable compensation before applying those skills in the real world. As the Joker once said, "Have you ever danced with the devil in the pale moonli--"
WAIT NO THAT'S NICHOLSON
goddamn it
GET OUT OF HERE
"If you're good at something, never do it for free~"
