Went out to feed the horses and apparently Annalie broke through the big sliding door and somehow managed to get into the grain room (which was shut and locked, she's known to break things). She got a hold of about 1/4 of a bag of pellets and half a bail of hay. Arabella could have gotten some but I doubt it because Annalie doesn't share well. I called the local vet and didn't get answer but left a message (surprise surprise) so I called the next vet and he is already on an emergency call. She's in her stall with water and hay....What do I do?
Edit: I might add that this is the Haflinger who is already overweight.
