Reno's been a little off her feed since Sunday night. She's also been sore in her left hind leg. That has been getting progressively worse from a slight limp to not wanting to put it down on the ground, no heat, swelling, or anything. Wednesday morning, her temp had gone up slightly (101.5) and she had a rather large knot on the right side of her throat (just behind her throatlatch). It didn't seem to hurt her to touch it, but she was even more down than she had been and barely nibbling at her food. I had to go to work, so I had Jamie look at it. She had no idea either, so she called the vet to see what she thought. The vet was pretty concerned and wanted to come out and take a look. Over the phone, the vet thought it was strangles. Once she got out there, she could pretty much tell that it wasn't. It was swollen to the other side of her throat by then. Basically could not find anything wrong with her. Her temp had gone up again to 102.5 (pretty high for Reno). Pretty much the only thing the vet could tell us is that it could possibly be a problem with her thyroid. Nothing wrong with her leg, so could only assume that it was somehow related. So she pulled blood on her. And now pretty much all we can do is sit back and wait for the results. Until then, she's on bute and stall rest. If nothing turns up on the blood work, she has no idea what she's going to do. Anyone have any ideas whatsoever? This came on very suddenly. She was fine Sunday day. I rode her and everything, not lame at all. Sunday night she didn't eat all of her hay. Then Monday morning she didn't eat all of her grain. During the day she laid down in the pasture under a tree the entire time. Monday night didn't eat anything, but actually finished all of her grain by the next morning. She is pretty much finishing her food (even her hay), but it literally takes her all night or all day to finish her little bit of grain.
