Hi, I am sorry that you aren't in the best situation with your filly. I don't know what your schedule is like and if you see your horse everyday. If you do, I would suggest working on her feet, give her a good brush, then work on her picking up her legs for you, clean her feet out with a hoof pick, and like someone suggested to bang her foot to simulate when the farrier is banging the nails in. As far as your clipping problem, next time you go to clip her most likely she will be problematic as she will remember it not being a good experience. So what I would do is, introduce her to the clipper while they are off, let her see it, smell it, then rub it on her neck a little bit. Take a couple steps back and turn them on to see her reaction. If she bugs out, shut them off and let her see it and smell it again, rub her neck too, try again the next day. Once she is comfortable with them being on and near her, rub it on her neck, moving towards the bridle path. I wouldn't try messing with her ears until she is comfortable having them around her ears. It will take time and she will get used to it. In the mean time with her ears, when your brushing her head, just touch her ears with your hands, rub on them, get her used to having her ears touched. I don't know what you have been doing, I am just trying to be helpful and good luck, I have trained many babies to be handled and this was my approach. We only used the twitch for the vet to inject horses joints and what not. Seriously good luck with her, hope you get into a better environment, for her and yourself!
