Death of our Two year old PWD

In May of 2001 we purchased our PWD. He was such a great addition to our family. Sadly he passed away suddenly for unknown reasons. On a Monday he was treated for an ear infection. We were given an ontiment and an oral antibiotic(Trimethoprim Sulfa 960mg). The vet also gave him a six month heart worm shot. By Thursday he was ill and had gotten very weak. We called the vet and they said to stop the medicine and bring him in if he was not feeling better by Friday. After only three pills he died. An autopsy was done at Cornell University and as of today they have not determined a cause of death. They are still waiting for the pathology test results. The report did indicate that his heart had no problem signs(they did note that it seemed small), there were no blood clots, and no problems with his stomach, no cancer . I am wondering if anyone has experienced a problem with this antibiotic. The vet mentioned that she thought he could have had an arrhythmia. I would appreciate any information or thought anyone might have. We are so very sad for our great pal Max. Thank you. bjk
