Horse is spooky "from behind"..any suggestions on ground exercises?
We have a young mare who is just a joy, very sweet horse. However her pet peeve is that she HATES to be in the back on trails or even walking across the yard to the arena. She is a wonderful leader but boy, once she's in the back she's on high alert and spooks easily, always worried about that predator (plastic bag, etc) behind her. I'd like some suggestions as to what ground exercises I could do to desensitize her in that area and then slowly work that up to the saddle. She's going to be seven, but still a little bit of a green bean, has some natural horsemanship basics (mostly Parelli but I'm open to ANY suggestions). Thanks!!
