This morning one of my alpacas was acting pretty ill. She was grinding her teeth, drooling, and groaning. She normally doesn't let anyone near her, but today I could just walk up and pet/put a halter on her. She was rolling a little bit, not much. She was mostly in a kush this entire morning. I took her temp and it was a little low: 98° When we tried to lead her to take her to the vet, she refused to walk. We ended up sliding her onto a board and carrying her up (she's a big girl, too: 192 lbs!) The vet drew blood and it seemed normal other than she was stressed out from the car ride(higher glucose levels). She was dehydrated from not drinking and drooling and therefore her electrolytes were off. The vet examined the fecal pellets and they weren't uniform in shape. They also had some mucous in them. She's not eating/drinking and not pooing/urinating. I did notice at the vet that she occasionally jerks her head back, like she's trying to regurgitate or "hiccup." The vet felt her throat for a blockage, found nothing, and gave her a pain killer. They decided to keep her overnight and give her an IV with fluids, etc. 1. Does anyone know what this could be? She was absolutely fine yesterday. 2. What would you do in my situation? I'm new to this and I don't really know what procedures or medications there are for various illnesses.
