Hi guys! I'm writing to see if anyone can offer me some training advice for my mare who seems to have separation anxiety. She's generally a well behaved horse, but she goes wild when her neighbors leave her or if I walk away from her while she's in the cross ties. When her neighbors leave, she screams and paces in her stall. If I leave her alone in the cross ties, she starts freaking out, to the point of rearing. It can be somewhat embarrassing and annoying but I'm not sure how to help her or how to stop it. Any advice? Thanks in advance!
