Why are pugs face pushed in?

Pugs have a brachycephalic (short-nosed) facial structure due to selective breeding for specific physical traits, which emphasize a flat, round face and short snout. This design is often favored in dog shows and by pet owners for its distinctive appearance. However, this trait can lead to health issues, such as breathing difficulties, because their shortened airways can restrict airflow. As a result, while their appearance is popular, it can come with significant health considerations.
