Well, it wasn't my horse, but a barn mates that gave me heart failure a few days ago. I was cleaning my stalls and kept hearing this long drawn out moan coming from one of the stalls down the aisle. I wander down and look in the stall to find a horse flat out on her side, lips pulled back, teeth clenched, eyes rolled up. She would take in a huge breath, hold it and then let it out with a long low moan.
I thumped on the wall of her stall, no reaction, no change. So I talk to her, yell at her...still nothing. So I grab my cell phone and get ready to call her owner as I start to go into her stall to check vitals to give to the vet...I thought for sure she was in full blown colic.
The INSTANT my hand rattled the snap to her stall door, she rolled up onto her chest and yawned and looked at me like "what the heck did you wake me up for, woman??"
Her owner got a chuckle out of it when I told him later that day.
