When I got to the barn this morning everyone was getting the horses turned out, but my youngest mare was in her stall still. I went to get her out and she was dripping with sweat. It's 40 degrees
They said she was pacing her stall but she has paced before without her getting herself that worked up. She's on Safe Choice and CoolCalories (basically rice bran).
One of the other owners suggested a supplement for mares that have bad heats. But if she's never been like this before, should I not get the vet out?
