As the owner of a Yorkie, they will never betray you. They basically train themselves. They just get up one day and decide "Today I'm going to learn how to stand on my hind legs and dance," and they'll do it. Amazing, amazing little dogs with the loyalty of labradors.
As someone who has worked in a pet store, small dogs fucking suck. Anything below 25 pounds is an abomination that should be shot on sight.
YEAH, THAT'S RIGHT. YOUR DOG SUCKS. MY DOG IS AWESOME. LET'S INTERNET FIGHT ABOUT THIS. CONAN THE CORGI REIGNS SUPREME. HE LAUGHS AT YOUR YORKIE. HE LAUGHS FROM HIS MOUNTAIN.
