I'm glad you said this - EEK! Was my first thought too.
Good luck with the foal
No worries it's just a rope halter underneath plus she's making an awkward face! LOL. I leave them on if just a quick ride around the barn lot and if one of my kids is riding so I can attach a lead rope.
Well this evening's check showed a lot of progress! She is jelly soft in the croup, her bag is much bigger and nipples have changed, and the foal is way back in her flank! This are huge changes from yesterday evening.
