My horse has become the barn grump. She has started pinning her ears at everyone and trying to bite some of them too. I didn't believe it as she has never done any of those things to me, but I finally saw it the other day when she tried to bite a passing rider. She has also started fence fighting. What could have sparked this change of personality? I should say I am leaving the current barn I am at because the food is horrid and the barn mngr did not even tell me about the fence fighting. I just kept finding ouchies on her and wondered how she got them as they are not turned out together. I have to wonder what else they are not telling me, but I will be outta there soon anyway. I plan on spending Fall and Winter working on all her ground basics again, but she hasn't had the biting problem with me. How do I keep her from trying to eat the other people? Thanks in advance!!!
