Six English Bull dogs from the same dog training camp were referred with main complaints of stridor, gagging and coughing. Diagnostic imaging studies on these dogs revealed hypoplastic trachea with/without bronchopneumonia. The mean age of affected dogs was $4.83{\pm}2.63$ months, while the mean body weight was $9.03{\pm}5.30$ kg. The mean ratio of the tracheal diameter to the thoracic inlet distance (TD/TI) was $0.085{\pm}0.022$ (normally 0.16 or greater), whereas the mean ratio tracheal diameter to the width of the third rib (TD/W3R) was $1.36{\pm}0.36$ (normally 2 or greater). All dogs had marked inspiratory dyspnea with variable degree of coughing. Of 6 dogs, 4 dogs had either bronchitis or bronchopneumonia. Treatment with antibiotics and bronchodilators made improvement on clinical signs on these dogs. Although some dogs still had mild inspiratory dyspnea (especially after exercise or excitement), most dogs live normally.
