Just a random question

Just wanted to know why is it such a stereotype to own a small dog only if you're a girl or have a different sexual orientation than most. I feel as though you should pic the breed that fits you based on their personality and your lifestyle not their size or by stereotypes unless of course you live in apartment and own a Great Dane

I love the yorkie breed and sometimes ill be walking my small dog and a woman will come up and say what a cute dog, is that yours and i'm thinking who's else would it be. I've gotten this ALOT!
