This was a hilarious thread! I was laughing so hard!! I have a 13 lb boy Booboo, a yorkie, that has the teeniest weenie and then I have a 4 lbs chihuahua, Baby that has a big one!! He used to squirt himself in his own mouth when he was young and then he figured out how to do a pelvis tilt so that he doesn't get himself in the face!! When he sits it sticks out farther than his knees!! Luckily, when we got him fixed it did shrink a little bit but it is still bigger than his brothers!!
