Longtime member, not active. Had a basenji with the same diagnosis back in 2004. He took a tremendous amount of bicarb each day, his Fanconi was being well managed, but he started having seizures at night. Our vet gave us something to stop the seizure that we'd administer rectally. We kept track of the number of seizures and they started becoming more frequent, to about twice a week, if I recall. The final seizure he had he went temporarily blind and howled and howled and we knew that was it was time. I just sat on the floor with him and cried. A couple months later we looked at photos we had taken of him right before and he looked very, very tired. Very much the hardest thing we had ever done was to let him go across the Bridge, but after looking at those photos, we had done the right thing. Our vet had told us that it was possible he would have a seizure and not come out of it, and we certainly didn't want that.
