Flat-faced dogs including Bulldogs, Pugs, and French Bulldogs face lifelong breathing difficulties and other serious health problems from extreme conformation breeding.
Brachycephalic dogs are among the most welfare-compromised of all companion animals because their health problems are structural and lifelong. Many cannot sleep without partially obstructing airways, exercise only minimally without respiratory distress, and face potentially fatal heat stroke from normal activities. The popularity of these breeds despite widely publicized welfare concerns illustrates how appearance preferences can override welfare considerations. Breeding reform, buyer education, and veterinary guidance discouraging purchase of severely affected animals are essential welfare interventions.
