Hi, I Have A Miniature/toy Schnauzer; Weighing 11 Pounds. She

Hi, I have a miniature/toy schnauzer; weighing 11 pounds. She is a 3.5 year old spayed female. She has a dry, hacking cough. But not a deep cough. She triggers a coughing attack if she moves quickly or tries to bark. She coughs, then gags and is done. She is not eating well and drinking minimal. She had a fluid bolus on Tuesday. It was thought it may be pancreatitis; my thought is it is more respiratory than gastric. When listening to her chest (w/a stethoscope) there is slight wheezing and a little rubbing.
