We have a mare that is just wasting away. She will NOT eat most of the time. This started about 2 years ago. We would feed her and she would refuse to eat. We keep her stalled so we can see if she eats her food or not. One day she will eat Strategy, the next, she won't. We have taken her to the vet, had blood drawn. The vets can't find anything wrong with her. He bloodwork shows to be that of a healthy, younger horse (she's 16). We've had 2 vets check her out, she's had her teeth checked out. We keep food in front of her at all times - sometimes she eats sometimes she don't. We have tried everything we know to try. Any suggestions would sure be appreciated.
