OH.. this is the horse that had the "running into things" problem isnt it?! It took me a while to figure that out
I hope to God he didn't have EPM like I thought (and posted on that thread) It almost sounds like he had a seizure. That's what ended up getting the horse I knew with EPM. She had the same symptoms your horse did... running into things, then when she went down for the last time she was too feeble to get up and had suffered a stroke =/
I'm very dissapointed with your vet for not giving you guys even the slightest opinion on what could be wrong with your horse. Is it the same vet that couldnt tell how old your horse was?
To those who are unfamiliar with her original post on this horse.. here's the link: Running into things.
Im sorry for your loss =/
