To me Sophie looks like a beautiful girl.
Showpug, Sophie's coat is very white, I saw her in a video Dr2little shared when they got the secret santa gifts.
Some people at training school saw my brothers male puppy squat to pee and so they assumed it must have been a girl and asked why he gave her a boys' name.
Later I learned that male puppies all squat until they learn from other male dogs who lift their leg.
