It really sucks waiting so long(almost a year at this point from her first breeding exam) only to loose it.
The vet thinks it might have been stress, this winter has had a lot of snow and ice, as well as abnormal temperature swings. It keeps going from above freezing to extremely cold and back again, almost weekly. Average daily high for this time of year is -2, forecast for tomorrow is -35. Its been really hard on the animals trying to adapt. The vet just had a late term abortion in one of his best brood mares for no logical reason.
just goes to show, breeding isn't all joy and adorable foals
