Flat-faced dog breeds such as French bulldogs, pugs, and bulldogs suffer from structural abnormalities causing breathing difficulties, eye problems, and skin infections throughout their lives.
Brachycephalic breeds live with structural health problems as a baseline. Breathing difficulties mean normal activities like playing and walking cause distress. Many cannot sleep lying flat due to airway obstruction. Heat is dangerous because they cannot pant effectively. Skin fold infections require constant maintenance. The popular perception that 'snoring is cute' in flat-faced dogs represents a normalisation of chronic respiratory distress. These conditions are entirely human-created and human-maintained through breeding choices.
