I once lease a horse that refused to lift her feet, you had to drag that sucker from the ground. So what we would do was once we took her out, we picked up all her feet, then we'd brush her, and pick up all her feet, then we'd groom her mane and tail then pick up all her feet, then we'd lunge and work her and then, you guessed it, pick up her feet. Then we'd ride or whatever and then after the first week or horrendously struggling the by the time the third week came and by that time if you started up by her shoulder and ran down, by the time you touched her knee, her leg would be up and waiting for you. It was wonderful. Plus she was tall, so I barely had to bend down.
