I posted on my little boer doeling a few weeks ago. She was shivering, off her feed, and feverish. We did a round of penicillin and she seemed ok for a few days, and then a relapse. The vet came out and checked her. He couldn't find anything obviously wrong. Her lungs, heart and rumen sounded fine. He said he didn't think she was carrying a high worm load. He gave us 3 shots of a stronger antibiotic. I haven't noticed her shivering since then, but she still isn't quite right. She is eating and drinking, but something is going on with her. She doesn't seem to want to keep her back feet both on the ground. She moves them restlessly. She is also noticeably smaller than her twin and just isn't quite as bright as her twin. Whatever it is, is internal and I have no idea how to find it or fix it.
