Skin fold infections are a painful, chronic welfare problem linked to selective breeding for extreme physical traits in brachycephalic and other wrinkled dog breeds.
Skin fold infections represent a systemic welfare failure rooted in breeding choices that prioritize appearance over animal health. The extreme wrinkled facial folds of Shar Peis, the nose rope and tail pocket of Bulldogs, and the excessive facial skin of Pugs are aesthetic features that cause measurable, chronic welfare harm. These animals live with ongoing skin pain, odor, and infection as a consequence of their breed standard. Surgery to reduce folds provides relief but treats symptoms rather than the cause. The breeding practices that produce these animals continue because demand for the look persists despite documented welfare harm. Choosing differently-bred or mixed-breed dogs is the most fundamental welfare action available to prospective dog owners.
