Thanks, Sarah...I appreciate your kind words.
Maureen...I didn't ask enough questions, I'm afraid. I should have asked and asked and asked... BEFORE the operation...but I trusted my vet...I have learned a huge lesson.
I think that vets, like other medical professionals, don't want to "condemn" one of their own by saying that they did something wrong...they just list possibilities...and one possibility was liver malfunction, because her liver test showed damage...but after she passed away, the neurologist called me. I was so worried about my breeding program and possible liver disorders that he did an autopsy (without charge) and called to say that her liver was normal...so he said, "We CAN'T SAY what caused this..." I personally believe that my vet over dosed the anesethics...but I have no proof...only circumstances that point to it.
I am relieved that she tested normal, genetically, however. That is a big load off of my mind.
