Without knowing if the cough is because of the collapsed trachea or CHF it is hard to treat. I don't know why a chest x-ray would be taxing for a dog. It would be helpful to see how enlarged the heart is and if there is fluid in the lungs. I see she is already on a diuretic furosemide which will help pull fluid from the lungs. Maybe an increase of that med would help. If cough is a result of compression of the airways by the enlarged heart, and not from pulmonary edema (fluid in the lungs) then prescriptions Hydrocodone or Butorphanol may be helpful. If the coughing is due to collapsed trachea then it would not be wise to give a cough suppressant because the coughing is what opens up the airway so they can breathe. Try to keep her weight down and not let her get hot. |
