Breathing, fatigue episode
I had a situation this morning that I have not seen before. Brought this horse in to feed, and when I went to let them all out (she had eaten all her feed and hay and pooped) I noticed this girl breathing fast, like she just galloped a marathon. Rediculously fast breathing. I led her out of the stall and she swaggered and was acting sedated. She went and laid down and the breathing issue continued. Called the vet. Horse was down about an hour, when the vet got there she jumped up and her breathing had calmed considerably and vitals were almost back to normal.
This was not characteristic at all of colic or choke. No biting of the flanks, no rolling, good gut sounds and she had just passed manure, no extended neck, gurgling sounds, difficulty swallowing, etc. I wondered if it may be a weed she ate, but the vet said it shouldn't have resolved that fast if it were toxicity. The vet gave her banamine and we'll run some blood work on her - she seems okay now, alert, eating and drinking as though nothing had happened.
Anyone run into something similar? I asked about HYPP as she does have some QH in her, but again the vet didn't really seem to think so.
They all get the same feed - Enrich 32 and hay. Everyone else was fine, alert, and curious about what was going on with their friend. So it seems like we can rule quite a few things out, but can't figure out what the culprit was just yet. Any ideas of things to look into?
