I just recently got my first horse/pony, a yearling paint filly named Legacy. I went out to check on her around 1am and she was perfectly fine, came to the gate as soon as she heard me. But about 5 minutes ago I went out again, and she didn't come when I called so I went into her run-in shelter she was laying down, and didn't get up when I went to her, however I nudged her probably 2 or 3 times, and she got up no problem. But she was stretching her her neck out and opening her mouth (not sure how to describe it. Kinda like she was trying to clear her throat?). I also then thought I felt a lump under her jaw. But when I left the shelter she followed me the whole way to the gate like she always does, and stayed watching till I went in the house.
It's been raining off and on all of yesterday, and for the last couple mornings its been chilly enough I wore a light jacket.
I know I'm bound to start noticing things I never would have before, and I'll probably worry over things I needn't but this really has me worried. I'm going back to check on her in a few minutes.
