Oh, I am so sorry. I also had goats die of meningeal worm and the vets were of little help, most never even mentioned it as a possibility. It's an awful parasite that takes a large dewormer dose to eradicate. If you have deer, snails, and wet pasture they'll get it every year. I stopped raising goats because they just can't handle our pastures.
If you have other goats watch for itching, especially along the spine and down the legs. They will have hotspots that move farther and farther down their legs. The goats begin to chew on themselves they are so itchy. I had one who chewed a large hole in himself.
