My 13-year old male toy poodle had symptoms of lethargy, anorexia, panting, hind legs weakness, gastrointestinal problems, vomiting, hair thinning, poor eye sight, enarged heart, and other symptoms suggestive of thyroid problems as I found out after his death. The vets in Alabama were unable to diagnose and they referred me to an internist for an ultrasound. The internist suggested that there was a intestinal obstruction which he said was life-threatening, and he recommended exploratory surgery. The surgeon found NO OBSTRUCTION--the internist had misinterpreted the ultrasound. The surgery was on Feb 14, and my pet died on Feb 21 due to complications. The surgeon kept my pet for 4 days and he released my pet to me while he still had diarrhea and anorexia. The surgeon gave me no prognosis or possible complications to watch for, but he only asked me to take my pet back in 2 weeks for suture removal and recommended a normal diet. I believed that my pet was recuperating slowly due to his age. I tried to feed him a liquid diet but he refused to take it. A day before he died, he had a seizure and rushed him to the emergency clinic. The vet there did not perform any diagnostic tests; he only put my pet in an oxygen cage and asked me to pick him up the following morning. Later that morning my pet was lifeless and rushed him again to a veterinary hospital. The vet there told us that he was in a coma and although she tried hard to revive him, he passed away at 1545 of Feb 21. To feel a closure for my dearest pet's who was like my lost child, I need to find out if all these symptoms were suggestive of Cushing's disease, why the internist misdiagnosed the ultrasound, and why he died 6 days after surgery although the surgeon never mentioned the possibility of this outcome. Why the seizure?
