I have a 17-month-old Nigerian dwarf doe experiencing some neurological symptoms. Two weeks ago I noticed a large patch of fur missing from her neck. We’ve had some issues with mites over the summer so I begin treatment with permethrin. She developed more patches on her face and around her ears. Two evenings ago I noticed she was wobbly in her hind quarters. The following morning the wobbling was worse and she seemed to have lost her vision. She could see my fingers moving in front of her face, but not much more. Her head tilts sideways and she finds me by following my voice. She’s eating and drinking and doesn’t seem to be in distress. I let my goat herd graze in our old horse pasture over the summer. The pasture is heavily deer infested, so my thought is possibly meningeal worms. The vet also thinks possibly thiamin deficiency. That wouldn’t account for the patches of missing fur though. I suppose it could be mites plus thiamin deficiency? The rest of my herd seems fine, with no symptoms whatsoever. I’m currently treating with fenbendazole and banamine. My husband is out picking up thiamin right now. any thoughts or ideas would be greatly appreciated. Thank you!
