I think it goes into the reputation of the dog/what people EXPECT the dog to be like. The pitbull has a more intimidating reputation therefore men are more drawn to it for appearance alone. On the opposite end, the chihuahua is more small and cutsie, therefore women are more drawn to it for its appearance alone. But when men go for chihuahuas or women go for pitbulls, it feels like it’s more than just for aesthetic reasons.
