No, I love all dogs equally (except pugs a little more ).
I owned a pit bull mix when I was in high school and although she was a spaz, she was as sweet as sugar.
I don't care for smooshed faced dogs, they are ugly bless their hearts. I like most dogs, A guy I know has a rat terrier and another guy has one that looks like a rat terrier, but he said it isn't. They are yappy, bitey and unfriendly and look like rats.
