Predominantly affected breeds included English Bulldog, Pug and Boston Terrier and the condition usually involves other upper airways diseases such as stenotic nares, elongated soft palate and everted laryngeal saccules.
Clinical signs may vary depending on the degree of tracheal narrowing and affected dogs usually present with upper airways noises such as stridor or stertor, exacerbated while eating or drinking. Aspiration pneumonia can develop in some dogs. The condition appears to be aggravated by obesity.
Although there is no specific treatment indicated for this condition, tracheal hypoplasia in some brachycephalic dogs can partially or completely resolve with growth to mature body size.
