Which dog breed is known to have congenital tracheal hypoplasia?

Congenital tracheal hypoplasia is a condition characterized by the underdevelopment or narrowing of the trachea, which can lead to respiratory difficulties. The English bulldog is notably associated with this congenital condition due to its brachycephalic facial structure, which predisposes it to various airway abnormalities, including tracheal hypoplasia.

This breed's unique anatomy can result in a flattened trachea and other associated respiratory problems, making them particularly vulnerable to this condition. In addition to tracheal hypoplasia, English bulldogs may experience other respiratory issues linked to their conformation, such as brachycephalic obstructive airway syndrome.

While other breeds may have respiratory issues as well, the English bulldog has a specifically recognized predisposition to congenital tracheal hypoplasia, distinguishing it from the other breeds listed.
