Hi. Well after almost $300. Em had an x-ray that showed a really tiny collapsted trachea. How she gets enough oxygen in I don't know. The heart is to be evaluated by a radiologist and I will get the reading hopefully by Saturday. The regular vet thought there might be some fluid around the heart, but she is not really sure. After seeing the collapsted trachea, I'm am really so sad, because I know she is having trouble breathing. Her cough is pretty well controlled by turbutrol, but that doesn't do anything for the trachea. There was an inhaler, but the set up and the medication came to over $100 a month. Maybe it would work, but then again???? This poor pup is 11 years old, and gets really upset when she is sick. So far she doesn't know how sick she is!
